Bean-related NoClassDefFoundError

[cybersack]

After I install a bean (by placing aBean.jar into /beans), I create an instance of that bean on a newly created form.

If I save the solution, quit Servoy and re-start....

Then I get this strange error (most times, but not always) when I switch to the form containing the bean. Does anyone have any ideas ?

thanks

that looks like a bean is needing something when it is deserialized what isn't there at the moment
Do you have a reproduceable solution with that bean for me?
