release_9.2.9

Feature Enhancements

Common-Canvas

• The three methods which were enabled in the previous release (that allow the setting of class names on nodes, comments and links) have been changed.

      setNodesClassName(nodeIds, newClassName, pipelineId)
      setCommentsClassName(commentIds, newClassName, pipelineId)
      setLinksClassName(linkIds, newClassName, pipelineId)

They will now set the provided class name on the group object <g> for the appropriate element in the DOM. Previously they assigned the class name to the background rectangle of the node/comment and for links to the link line and arrow head. This approach allows constituent parts of each group element to be customized based on a single class assigned to the parent group <g>.

• The class names for link lines have been changed. Previously the class that indicates the type of link (for example, d3-data-link) was assigned to both the parent group <g> object of the link and also to the line element <path> within the group. Now it is only assigned to the parent group <g> element. You probably won't see any sign of this change but, for completeness, if you are overriding any of these classes to provide your own line styles for the different types of link:

.d3-data-link
.d3-comment-link
.d3-object-link
.d3-association-link

You should change them to:

.d3-data-link .d3-link-line
.d3-comment-link .d3-link-line
.d3-object-link .d3-link-line
.d3-association-link .d3-link-line

Common-Properties

• Just bug fixes.

#468 Set classname API should set class name on group objects (#469)

release_9.2.8

Feature Enhancements

Common-Canvas

• The Canvas Controller now supports methods that allow the application to add class names to the canvas objects. These methods were present in the API before but not functional. The methods are:

      setNodesClassName(nodeIds, newClassName, pipelineId)
      setCommentsClassName(commentIds, newClassName, pipelineId)
      setLinksClassName(linkIds, newClassName, pipelineId)

  These will add the provided class name (string) to the class name attribute in the DOM for specified object. For nodes and comments the class name will be applied to the background rectangle of the node or comment, for links it will be applied to the link line and arrow head (if there is one).

• The Canvas Controller now has three new methods that retrieve the class name applied to the object specified.

      getNodeClassName(nodeId, pipelineId)
      getCommentClassName(commentId, pipelineId)
      getLinkClassName(linkId, pipelineId)

Common-Properties

• A new option schemaValidation has been introduced in the propertiesConfig object. If set to true, schema validation will be enabled when a parameter definition has been set in CommonProperties. Any errors found will be reported on the browser dev console

• A new UI hint class_name has been introduced for common properties groups and parameters

• A new UI hint custom_value_allowed has been introduced for common properties dropdown controls. If set to true, users may enter a new value for the dropdown.

• A new multiselect dropdown control has been added.

• Numerous accessibility improvements have been made.

release_9.2.6

Feature Enhancements

Common Canvas

• The canvas objects (nodes, comments, links) can now be offset from the origin by a specified x and y amount when the canvas is first opened. This might be useful if you know your canvas always needs to be moved by a fixed amount of space regardless of what canvas objects are displayed. To specify the x and y amount create a canvas config object like this:

  const config = {
      enableCanvasLayout: {
          initialPanX: 100,
          initialPanY: 200
      }
  };

  where the numbers are coordinate positions from the origin which is, by default, the top left corner of the canvas.

  Note: These values will only be used when other saved zoom behaviors are not specified. Examples, of saved zoom behaviors are:

  • A saved zoom object in the browser's Local Storage when the canvas config value enableSaveZoom is set to LocalStorage
  • A saved zoom object in the pipeline flow when the canvas config value enableSaveZoom is set to Pipelineflow
  • When the canvas config value enablePanIntoViewOnOpen is specified as true

Issues resolved

#405 Ability to position nodes on the canvas during componentDidMount (#407)

release_9.2.5

Feature Enhancements

Common-Canvas

• The ghost image displayed when dragging a node from the palette now works correctly when the Chrome or Firefox browser page is zoomed. Note: There is still an issue with this on Safari.
• Zoom amounts are now saved in a valid format in the pipelineFlow document when enableSaveZoom is set to "Pipelineflow"
• Comments that are positioned with either a negative x or y coordinate are now saved to a pipeline flow document that conforms to the pipeline flow UI schema.
• Elbow lines now behave the same way as curved lines when the target node is 'behind' the source node. That is, they loop around the outside of the source and target nodes instead of going underneath them.
• The Paste option does not now appear in the Edit submenu for Nodes, Links and Comments.
• Port circles are now removed if an empty inputs or outputs array is specified for a node in the Canvas Controller API
• The Canvas Controller API now returns copies of objects from the object store instead of a pointer to the actual data in the object store.

release_9.2.2

Feature Enhancements

Common-Properties

• #359 a new “readonlyTable” is introduced. A complex structure can be set to be readonly by specifying “control”: “readonlyTable” in the parameter_info section of the parameter definition. Examples can be found at https://github.com/elyra-ai/canvas/blob/master/canvas_modules/harness/test_resources/parameterDefs/readonlyTable_paramDef.json

Issues resolved

#368 Add dark themed CodeMirror support for Expression Builder (#372)
#359 readonlyTable control (#371)
#349 Display checkbox tooltips next to label in common-properties (#350)

release_9.2.1

Feature Enhancements

Common-Canvas

• #12 The context menu Paste option now pastes objects from the clipboard at the mouse pointer position where the context menu was requested.

• #357 Four new API methods have been added to Canvas Controller:

  getNodeInputPorts(nodeId, pipelineId)
  getNodeOutputPorts(nodeId, pipelineId)
  
  setNodeInputPorts(nodeId, inputs, pipelineId)
  setNodeOutputPorts(nodeId, outputs, pipelineId)

  The second two can be used to add new ports to the node; they will cause the canvas to refresh to reflect the ports specified.
  See the canvas controller API documentation for more details.

• Warning: In this release the internal structure of canvas objects in the DOM has changed. Nodes, Links and Comments are now inside their own group (<g>) element. This means, if you have any tests that use selectors to identify objects (nodes, comments, links) like this:

  svg > g > g[data-id=123]
  

  the selector would now be:

  svg > g > g > g[data-id=123] 
  

Common-Properties

• #255 Nested complex structures are now supported in common-properties. Complex structures that can be nested includes: structuretables, structurelisteditors, structureeditor and list controls. Examples are added to the test harness https://github.com/elyra-ai/canvas/tree/master/canvas_modules/harness/test_resources/parameterDefs

Issues resolved

#366 Some toolbar icons not visible with dark theme (#367)
#362 Selectable links disappear under comment when hovering stops (#363)
#167 Paste button is always enabled (#364)
#255 Complex types support complex types sub-controls (#256)
#360 Wide node labels truncated when displayed as part of ghost image (#361)
#357 Port addition/deletion UI render bugs (#358)
#12 Clipboard paste with context menu should add objects at mouse pos… (#353)

release_9.1.9

Feature Enhancements

Common-Canvas

This release contains the two bug fixes mentioned below; one of which is high priority.

Common-Properties

No changes

Issues resolved

#354 Can't delete the node on click of delete button of keyboard for the 1st time (#355)
#351 Link selection highlighting incorrectly displayed when link selection switched off (#352)

release_9.1.8

Feature Enhancements

Common-Canvas

• Two new properties are now supported for decorations:
  • distance - this can be used for positioning a decoration at an offset distance along a straight connecting line between nodes. An example of the usage of this new property can be seen in the detached links sample application in the test harness.
  • temporary - if set to true the decoration will not be written into the pipeline flow document when it is requested using CanvasController.getPipelineFlow()
    See the decoration documentation in the wiki for details.

Common-Properties

• #319 - For accessibility, the landmark role complementary was added for common-properties. This means the right flyout view of common-properties is now wrapped in an <aside /> tag. Earlier this was a <div /> tag. This will change any selectors you might use for common properties if you have included the tag name (div) in the selector. There is no change in the modal view.

Issues resolved

#339 Link decorations improvements (#342)
#347 Translations (#348)
#345 Empty toolbarConfig object produces error messages in developer console (#346)
#343 Fixed dropdown menu border blocked by Close button (#344)
#319 Add landmark role for common-properties (#340)
#325 Fixes expression builder onBlur behavior (#336)
#337 Double click on node causing text areas in properties to be highlighted (#338)
#328 Prevent evt propagation when selecting a dropdown option within a table row (#335)
#333 Properties table performance (#334)

release_9.1.6

Feature Enhancements

Common-Canvas

• A new boolean config variable called enablePositionNodeOnRightFlyoutOpen has been added. When set to true, if the right-side flyout is open the currently selected node will be automatically positioned in the center of the canvas area (viewport). See the wiki section for details: https://github.com/elyra-ai/canvas/wiki/2.1-Config-Objects#enablepositionnodeonrightflyoutopen

• Two new CanvasController API methods have been added to allow the host application to modify the source and target information for a link. These are:

  • setNodeDataLinkSrcInfo(linkId, srcNodeId, srcNodePortId, pipelineId)
  • setNodeDataLinkTrgInfo(linkId, trgNodeId, trgNodePortId, pipelineId) 

• With enableLinkSelection set to Detacahable, a node can now be a attached to either the source-end or the target-end of a fully-detached link.

• Select All actions with the keyboard (Ctrl-A) and the context menu will now select the links on the canvas as well as comments and nodes (when enableLinkSelection is set to LinkOnly, Handles or Detacahable).

• Nodes with empty inputs and/or outputs properties are now correctly written out into PipelineFlow documents returned from CanvasController.getPipelinFlow()

Issues resolved
