Loading classes from WEB-INF/lib

Dear ivyteam

In our project we'd like to have the following structure: Our ivy project contains a jar which has some Java interfaces. Then we'd like the implementations for these interfaces in another external jar that we can deploy independently. Our idea was to put into the WEB-INF/lib folder.

But if we try to load the class from the jar (using ClassLoader#loadClass) we get a NoClassDefFound exception. Is there any way to get such a structure to work? Maybe with some class loader magic?

Best regards Lars

Issue with receiving and sending the same signal in a process

Hi everyone

So I have a process with a User Task that has a signal boundary event that listens to a certain signal X. After the user task is finished I check some values and depending on that I want to send the same signal X. See the image below:

But when that signal is sent I get the following exception:

java.lang.IllegalStateException: State of Task must be one of the following values CREATED, RESUMED but is DESTROYED
  at ch.ivyteam.api.API.checkObjectState(API.java:323)
  at ch.ivyteam.ivy.workflow.internal.Task.end(Task.java:2642)
  at ch.ivyteam.ivy.workflow.internal.Task$49.execute(Task.java:2618)
  at ch.ivyteam.ivy.persistence.base.AbstractPersistencyService.execute(AbstractPersistencyService.java:176)
  at ch.ivyteam.ivy.persistence.base.AbstractPersistencyService.execute(AbstractPersistencyService.java:233)
  at ch.ivyteam.ivy.persistence.base.ClassPersistencyService.execute(ClassPersistencyService.java:660)
[...]

I uploaded a demo project here: https://drive.google.com/file/d/0B3V8Sh7Fl7FXR3dzMFhzVzJlTEk/view?usp=sharing

Thanks in advance
