[xTend] GLOBALVAR causes exception [message #519125]

Hello.

After migrating from Openarchitectureware to MWE I can't define a
globalVarDef anymore.

My workflow looks like this:

My workflow looks like this:

<component class="org.eclipse.xpand2.Generator">
<fileEncoding value="UTF-8"/>
<metaModel idRef="mm.framework"/>
<expand value="com::lm::visage::m2t::framework::Pojo::main FOR
frameworkModel"/>
<globalVarDef name="javaPackage" value="com.test.something" />
</component>

I access this global var in an Xtension file by this simple function:

String packageName() : GLOBALVAR javaPackage;

As soon as that function is called, I get the following Exception:

Mar 6, 2010 9:29:45 PM
org.eclipse.xtend.expression.AbstractExpressionsUsingWorkflo wComponent
invokeInternal
SEVERE: Error in Component of type org.eclipse.xpand2.Generator:
EvaluationException : Couldn't find type or property 'com'
nofile[0,3] on line 1 'com'

I'm not sure to proceed.
Of course I don't have to define this global, I but I would prefer to.
Can anybody tell me what I did wrong?

Thanks!

The text in value is interpreted as an expression an id evaluated
against the workflow context.
If you want to pass a string, you need to set the value in quotes:

<globalVarDef name="javaPackage" value="'com.test.something'" />
