[jbpm-dev] Quick question on wiring / EJB3 as process variable

you even managed to find a bug!  so you even found more then you're looking for :-)

an EJB3 matcher and variable type would be great to include.

I've reproduced your problem and fixed it.  Once I've committed it (in the next 
hour or so) then you'll find an example in 
modules\test-cfg\src\test\java\org\jbpm\test\customtype\CustomVariableTypeTest.java

Thanks for reporting it!  Let me know if there is any other problem you 
encounter with adding ejb3 variable support.

regards, tom.
