Unable to set the default value

[schaitanya1]

Hey, First of all, thanks a lot for this great component.
The issue I'm facing is when I try to set a default value on the Lookup when we load this, It loads the Id I give but the name is blank.
Can you please let me know where I'm going wrong.

The true above is coming because I set the parameter selectedName="true" if this is not set then I get blank value there.

Below is my code.
<c:lookupField
objectAPIName="Case"
label="Related To"
returnFields="['CaseNumber','Id']"
queryFields="['CaseNumber']"
selectedId="{!v.newTask.WhatId}" showAddNew="false"
showIcon="false"
selectedName="true"
/>

v.newTask.WhatId this value is set in the js controller.
Thanks a lot in advance for all the help.

Cheers,
Sri.
