Short answer: use _ instead of . in your variable names.
Jelly is interpreting the j:if and looking for object idl, to have property already which has property generated. Or equivalent to: idl.getAlready().getGenerated(). Changing the . to _ will make it more like a Java variable idl_already_generated.

Hello
In a maven.xml, I have the following code:
<j:set var="idl.already.generated" value="false"/> <u:available file="${idl.generated}"> <j:set var="idl.already.generated" value="true"/> </u:available>
<ant:echo message="${idl.already.generated}"/>
<!-- the following line allways prints true-->
<ant:echo message="${!idl.already.generated}"/> <j:if test="${!idl.already.generated}">
<ant:echo message="generating idl bindings"/>
<!-- idl compiling goes here-->
</j:if>
The second echo always prints true, so maven always compile my idl's. I've tried a lot of severals combinations (ant:available, ${idl.already.generated == null}, ${idl.already.generated != null}, etc) but I can't make it work.
Somebody can help me?
Thanks in advance Nelson Arapé
