Hi,

I'm facing sporadic EvaluationExecptions in xtend and xpand scripts. It happens at random places and only from time to time.
Here are a few examples (I can provide more logs):

20594 ERROR AbstractExpressionsUsingWorkflowComponent - Error in Component of type org.eclipse.xpand2.Generator:

I'm running my xtend and xpand files from a maven build (it runs mwe workflows from unit tests). I'm using xpand 0.7.2.
You might think it happens due to errors in the xtend files. But I get these errors just by repeating a stable build a few times.
After some runs the exeception will occur at random places (without changing any files).

I would love to create a reproduce-able example, but it happens randomly and only in the context of a larger project.

Do you have any ideas about this issue? What should I do to get more insight into this problem?

Best regards

Christoph

christoph,

same for me.... randomly and only in large complex projects after
executing some runs of worlkflows
the only thing what helps is restarting eclipse

I posted this some time ago

would be really great if someone has an idea

Hi,

is it possible for you to run the workflow in debug mode and add an
exception breakpoint for EvaluationException?

And than of course tell us about the context (i.e. what causes the
exception).

Thanks,
Sven

Sven,

I've connected the eclipse debugger to the maven build. Below you find the callstack, the attached pictures shows the context of the exception.

Any help is highly appreciated.

Thanks

Christoph

Please provide the stack trace of the handled RuntimeException.
Maybe, you want to contact me via skype, so we can hunt that bug down.
Skype name is : svenefftinge

Thanks,
Sven

Hi Sven,

I will provide the requested information of the runtime exception as soon as possible. Thanks for offering your support via skype. Unfortunately I have no access to skype from my office, but I can call you by phone. I will contact you as soon as I can provide more details (tomorrow).

Regards

Christoph

hi sven,

.... its not easy to catch... sometimes I need one hour or more of
different generations and then suddenly it happens
but I'm just implementing some new redview features into my templates
and have to generate and test all projects -
so I'm sure it will happen ;-)

can do it on friday ... today I'm at eclipse democamp in frankfurt

downloaded 0.8.0 N-Builds 2009-12-01 to test it, but couldn't do it,
because I run into the same problems as Miles Parker:
0.8.0 (M3 or latest N-Builds) runs 18x - 40x slower, so there's no
chance to start my big workflow if a small one
needs 1h:24m instead of 2m ;-)

reverted to 0.7.2

Hi,

to get rid of the 0.8 performance issue, I've replaced the WeakCache.class in my local xtend 0.7.2 jar with the fixed version. In this setup the issue still exists and is not fixed.

Regards

Christoph
