"Designer - Mixed up global/input/output variables in imported processes"

Hi,

we are migrating from using the drools eclipse BPMN2 modeler to the designer 
2.4 war. When I import the processes into the guvnor, edit them in the designer 
and save and export them they fail to execute in the drools runtime.

I narrowed the problem down to global variables, data input and output 
variables that have the same name. They will get mixed up leading to missing 
<bpmn2:dataInputAssociation> elements. 

This is visibleĀ  in the editor for data assignments for work items. If I try to 
map e.g.
* the global variable 'acl' to the input parameter 'acl' and
*  the output parameter 'acl' to the global variable 'acl',
they get mixed up. If I open the drop down list again, ist is always the global 
variable that is selected. This occurs in both the "From Object" and "To 
Object" drop down list.

This leads to a missing <bpmn2:dataInputAssociation> for the 'acl' variable in 
the generated BPMN2. The <bpmn2:dataOutputAssociation> for the 'acl' output 
parameter gets generated correctly however.

Is this an error in the designer or is it prohibited to use the same variable 
names, even if it was working fine in the eclipse modeler? Is there a way to 
work around this using the designer?

Thanks
Olaf
