[XTEND] [MWE] Error when running ProfilerComponent in 0.8.0M4 sample project [message #507636]

I just updated my Eclipse 3.5.1 to new version 0.8.0.M4 of Xtext, Xpand/Xtend/Check and MWE. All seems to run fine, I'm able to use the Xpand project Wizard to create the sample project, edit the DSL etc.

However, inside this sample project, when I call the generatorWithProfiler.mwe workflow to create and render a profiling model, I'm getting this exception:

2218 INFO  CompositeComponent - Generator: generating 'org::eclipse::xtend::profiler::templates::Html::Main FOR profilingResult' => profiling
2281 ERROR AbstractExpressionsUsingWorkflowComponent - Error in Component  of type org.eclipse.xpand2.Generator: 
	EvaluationException : No Definition 'org::eclipse::xtend::profiler::templates::Html::Main for profilermodel::ProfilingResult' found!
	[23,79] on line 1 'EXPAND org::eclipse::xtend::profiler::templates::Html::Main FOR profilingResult'

2281 ERROR WorkflowRunner     - Workflow interrupted. Reason: No Definition 'org::eclipse::xtend::profiler::templates::Html::Main for profilermodel::ProfilingResult' found!
2281 ERROR WorkflowRunner     - [ERROR]: No Definition 'org::eclipse::xtend::profiler::templates::Html::Main for profilermodel::ProfilingResult' found!(Element: EXPAND org::eclipse::xtend::profiler::templates::Html::Main FOR profilingResult; Reported by: Generator: generating 'org::eclipse::xtend::profiler::templates::Html::Main FOR profilingResult' => profiling)

Seems the template couldn't be found which is a bit strange given the fact that org.eclipse.xtend.profiler_0.8.0.v200912151404.jar is available in Plug-in Dependencies, and I can locate the Html.xpt in this JAR file.

Any idea? Is the sample project wizard not working correctly, or anything else misconfigured?

Thanks,
Christoph.

This has already been fixed. Will be available in the next milestone.
The problem is that the EPackage for the profiler is not initialized.
Should be enough to add a standalonesertup component where you
initialize that package.

Something like this:

<bean class="StandaloneSetup">
<generateEPackage
class="org.eclipse.xtend.profiler.profilermodel.ModelPackage "/>
</bean>

Cheers,
Sven

Hi Christoph,

there was a bug in the sample project wizard that was fixed after the
0.8.0M4.
A workaround is to register the
org.eclipse.xtend.profiler.profilermodel.ModelPackage in your
StandaloneSetup via registerGeneratedEPackage.

Regards,
Sebastian

Thanks for your prompt answers, but... I can't figure out how to register the model package. This is what I tried:

	<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup" >
		<registerGeneratedEPackage class="org.eclipse.xtend.profiler.profilermodel.ModelPackage"/>
	</bean>

But it gives me another error: Incompatible Classes: 'org.eclipse.xtend.profiler.profilermodel.ModelPackage' is not a subclass of the expected class 'java.lang.String'.(Element: bean registerGeneratedEPackage class='org.eclipse.xtend.profiler.profilermodel.ModelPackage ' in D:/JavaTools/dev/eclipse-ws/test/my.generator.project/src/wo rkflow/generatorWithProfiler.mwe:10; Reported by: -UNKNOWN-)

My StandaloneSetup (from org.eclipse.emf.mwe.utils_0.8.0.v200912151301.jar) doesn't seem to have a registerGeneratedEPackage method...

Wrong version of that JAR? What else?

Hi Christoph,

you'll have to use 'value=".."' instead of 'class=".."'.

<bean class="..StandaloneSetup">
<registerGeneratedEPackage value="org..ModelPackage"/>
</bean>

Sebastian
