Enable the multiple pages diagram feature

[oanalavinia]

Drawio offers the possibility to have multiple pages per diagram, check https://drawio-app.com/blog/multiple-pages-per-diagram/

I propose to support this feature in the Diagram Application as well.

Note that right now, if a diagram containing multiple pages is imported, you do have the UI for navigating through them.

But, upon editing, only the first diagram is displayed and the rest will be deleted on save.

estimation will be done first.

For me, this seems more like a critical bug than an improvement. When migrating content from Confluence to XWiki, all diagrams become uneditable because saving any changes will result in the deletion of all remaining diagrams in other pages.

Hi @mikus-strazdins thank you very much for your message. This is a current limitation of the Diagram Pro application, as it supports only single diagrams. However, we understand that multi-page diagrams are requested and may be especially required for Customers migrating from Confluence to XWiki. Therefore we are currently investigating the work required to provide this improvement. We will be back with an update as soon as possible.

Hi @jkalinovskis thank you for your message. The evaluation will be finalised next week and we will come back with an update regarding the plan for this feature.

Found some issues with this implementation, reopening for fixing it

[oanalavinia]

It looks like there is another bug that I haven't noticed.. #260 . I was trying different ways to fix the previous bug, so I didn't noticed that I broke again another part of the feature.
Doing another release with a fix for it, sorry for that

@mikus-strazdins you can now install the last diagram version for using this feature.
Note that there 2 issues opened (#261 #262 ), but they don't affect the functionality of the feature. Feel free to open other issues if you find them :)
