[EMF Forms] Tree Master Detail Recursion [message #1745700]

Hi Everyone,

Im having a problem with using a Tree Master Detail View to display properly and would greatly appreciate any help you could offer.

The TL;DR version of my problem:

The tree master detail view recursively opens nested versions of itself for branch nodes, despite me defining two view models for the branch type (as per the tutorial) and including the the following in my plugin.xml:

<file filePath="model/TestCaseGroupDetail.view">
	<filter key="root" value="true">
   	</filter>
</file>

<file filePath="model/TestCaseGroupTreeMaster.view">

In mode detail:

I have a tree data structure defined in my model. Each node implements TestCase. Branches are instances of TestCaseGroup; leafs are ExampleTestCase.

I have one view model defined for ExampleTestCase

I have two defined for TestCase Group (TestCaseGroupDetail.view and TestCaseGroupTreeMaster.view)

TestCaseGroupDetail.view contains:

<org.eclipse.emf.ecp.view.model:View xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" xmlns:org.eclipse.emf.ecp.view.model="http://org/eclipse/emf/ecp/view/model/170" xmi:id="_B-60kJIdEeaEPv13gebBNw" name="TestCaseGroup" ecorePath="/com.dnvgl.csec.jtf.core.model/model/model.ecore">

    </domainModelReference>
  </children>
</org.eclipse.emf.ecp.view.model:View>

TestCaseGroupTreeMaster.view: contains:

<?xml version="1.0" encoding="ASCII"?>
<org.eclipse.emf.ecp.view.model:View xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:org.eclipse.emf.ecp.view.model="http://org/eclipse/emf/ecp/view/model/170" xmlns:org.eclipse.emf.ecp.view.treemasterview.model="http://org/eclipse/emf/ecp/view/treemasterview/model" xmi:id="_3w2eEJIcEeaEPv13gebBNw" name="TestCaseGroup" ecorePath="/com.dnvgl.csec.jtf.core.model/model/model.ecore">
  <rootEClass href="http://www.example.org/model#//TestCaseGroup"/>
  <children xsi:type="org.eclipse.emf.ecp.view.treemasterview.model:TreeMasterDetail" xmi:id="_MDYjIJIdEeaEPv13gebBNw" name="Test Tree"/>
</org.eclipse.emf.ecp.view.model:View>

The view of the initial TestGroup is displayed as desired. However, clicking on child TestGroup's opens a whole nested TreeMasterDetail view in the details panel (i.e recursion). I thought this was what the <filter ..> stuff in the extension point was meant to prevent?

I'm relatively new to EMF and EMF forms and so may be doing something stupid. Am i missing something?

Thanks in advance for your help!

Hi Bob,
Your setup looks correct.
Could you share your model and view model so I can take a look at this?

Cheers,
Eugen

Hi Bob,
I created two projects out of your provided files. (see attached zip)
For me everything works as expected.
index.php/fa/27390/0/

Can you please check your view registration?

Hi Eugen,

Thanks again for the reply.

I have copied the copied and pasted the extension point info from your exmple view project without change.

Unfortunatly the problem still occurs. The top Group in the tree displays as expected, but nested sub groups cause nested/recursive views. As per this screenshot:

Hi Bob,

I think you found an error in the docu.
You are using root = true as filter. It must be detail = true.

I hope this will fix the behavior.
If so please let me know, so that we can fix the docu asap.

Cheers,
Eugen

Hi Eugen,

Fixed!

As you suggested i changed "root = true" to "detail = true" and it now works perfectly Smile

Thanks for your help in figuring this out!
