index.php/fa/4213/0/Hi,

I followed chapter 19.2.1 Suppressing Model Objects of the 'EMF 2nd Edition' book and all is nice and good but ...

First to show you excerpt from my model instance:

ValueSet
|-Tokens
|-TokenA
|-TokenB
.
.
|-TokenN

Token object instances TokenA to TokenN contain one child object called Reference which I want to have suppressed i.e. not displayed in the object hierarchy view. I have followed steps described in the above mentioned chapter and can see properties view for the child object merged together with the Token properties. The problem is that Reference properties are not refreshed when moving from TokenA ,say, to TokenB.

You can see the attached screenshot - where token T10 doesn't contain any reference value 'COMP'. The reference value 'COMP' is part of the token T1 and T1 was the first token I clicked on before making this snapshot.

Any idea someone?

Thanks,

Otto

I would expect this code in the generated editor to refresh the
properties view whenever a command is executed:<br>
<br>
<small>&nbsp;&nbsp;&nbsp; // Add a listener to set the most recent command's
affected objects to be the selection of the viewer with focus.<br>
&nbsp;&nbsp;&nbsp; //<br>
&nbsp;&nbsp;&nbsp; commandStack.addCommandStackListener<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (new CommandStackListener()<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; public void commandStackChanged(final EventObject event)<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; getContainer().getDisplay().asyncExec<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (new Runnable()<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; public void run()<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; firePropertyChange(IEditorPart.PROP_DIRTY);<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // Try to select the affected objects.<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; //<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Command mostRecentCommand =
((CommandStack)event.getSource()).getMostRecentCommand();<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if (mostRecentCommand != null)<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
setSelectionToViewer(mostRecentCommand.getAffectedObjects());<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if (propertySheetPage != null &amp;&amp;
!propertySheetPage.getControl().isDisposed())<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; propertySheetPage.refresh();<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; });<br>

Hi Ed,

Thanks for your reply. The generated code you mentioned in your reply is present in the generated editor in the 'initializeEditingDomain()' method.

There are two things which could possibly affect behavior of my editor and are different from example described in your book:

1. usage of tabbed property view based on 'AbstractPropertySection'; you can see it on my original snapshot.

2. parent of token objects (displayed as 'Tokens' node on the original snapshot) is non-model intermediary object created as described in the chapter 19.2.3.

I have done some more experimenting and changed underlying token object definition in the model from 'Singleton' to 'Stateful' and it behaves as I need it. I am not sure if this is right approach to solve the problem though.

What do you think?

Thanks,

Otto
