[rules-users] Error in Drools when clicking "Generate Task Form Template"

[Sadiroveski]

Dear helpers,

I designed process in drools with human tasks included, add the variables,
inputsets and bindings.
When I clicked on the "Generate Task Form Templates", to add forms I got the
following:

----------------------------------------------------------------------------------------
