Hi Louis, Dimitrios,

I'm probably doing something really stupid, but I have a problem using
EGL from an ANT workflow. I have the following task invocation:

<epsilon.egl src="templates/BlockFactory.egl"
target="${dir}/tetris/BlockFactory.java">
<model ref="tetris" as="Tetris" />
</epsilon.egl>

But instead of simply loading the template and generating to the
specified file, I get the following exception:

java.lang.ClassCastException: java.lang.String cannot be cast to org.eclipse.epsilon.egl.EglFileGeneratingTemplate
at org.eclipse.epsilon.workflow.tasks.EglTask.examine(EglTask.j ava:32)
at org.eclipse.epsilon.workflow.tasks.ExecutableModuleTask.exec uteImpl(ExecutableModuleTask.java:118)
at org.eclipse.epsilon.workflow.tasks.EpsilonTask.execute(Epsil onTask.java:41)
at org.apache.tools.ant.UnknownElement.execute(UnknownElement.j ava:288)
...

Now, I know that the whole template and target handling of EglTask has
recently been overhauled quite a bit, so I just wonder whether this
might simply be a regression somewhere? Or is there something I'm missing?

Cheers,

Steffen

That's a regression indeed. Could you please file a bug and post the
link here? This happens only when a target is specified in the
epsilon.egl task so as a workaround you could remove the target and use
another template to call your (now) main one and store its result from
there.

Cheers,
Dimitris

Hi Steffen,

I've fixed this in the SVN and rolled out a new interim version
(v0.8.9.201004211415).

Cheers,
Dimitris
