[JELLY] - Jelly/Jexl question

It may be that I'm being impatient (please ignore | forgive me if you think 
this is the case), but I'm wondering if all of my problems with Jelly/SWT 
relate to Jexl behavior:

(reference: my message with subject: how to enable logging? (SWT specific))

My simple question is this:

<scrolledComposite var="scrolled" parent="${sash}" type="V_SCROLL, BORDER"  
background="132,251,232">
			 	<fillLayout/>
			 	<composite var="grid">
				 	<fillLayout/>
			 		<label text="yay" background="12,12,12"/>
			 	</composite>
		 		<onEvent type="Resize" var="resizeEvent">
		 			${grid.computeSize(scrolled.getBounds().width, SWT.DEFAULT) }
		 		</onEvent>
		 		${grid.setSize(10, 10) }
			</scrolledComposite>

Will Jexl be able to parse and evaluate 
"${grid.computeSize(scrolled.getBounds().width, SWT.DEFAULT) }"

?

Am I doing "non-jexl-nice" things here?

OK.  Yes, that's the unqualified name of the class. Using a FQN does not seem 
to work either... 

However; if I change to using:

"${grid.computeSize(scrolled.getBounds().width, scrolled.getBounds().height) 
}"

still I get no joy :-(.

The jelly debug output shows:
1346 [main] DEBUG  - findVariable: grid value: Composite {}
1430 [main] DEBUG  - Evaluating EL: 
grid.computeSize(scrolled.getBounds().width, scrolled.getBounds().height) 
1431 [main] DEBUG  - findVariable: grid value: Composite {}
1431 [main] DEBUG  - findVariable: scrolled value: null
1431 [main] DEBUG  - findVariable: scrolled value: null
1431 [main] DEBUG  - findVariable: scrolled value: null
1431 [main] DEBUG  - findVariable: scrolled value: null
1431 [main] DEBUG  - value of expression: null

I tried also using "scrolled.bounds.width" with the same result.

Is there a reference for what Jexl supports?

Neil,

If SWT.DEFAULT is a static member of SWT class than I think the answer 
is: jexl doesn't know how to handle constants... (a bug should be filed, 
I think this was discussed recently on the list about DISPOSE_ON_CLOSE).

Oh, plus you were'nt providing the full-classname of SWT, or ?
