Business Rule Task has not got property ScriptLanguage. I think that this property is important for onEntry/onExit action. Its changes is apllied on attribute scriptFormat of elements drools:onEntry-script and drools:onExit-script.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. create process (Start -> Business rule Task -> End)
2. activate Business Task
3. open Extra Property

Actual results:
Properties: Ruleflow Group, On Entry Actions, On Exit Actions

Expected results:
Properties: Ruleflow Group, On Entry Actions, On Exit Actions, ScriptLanguage


Workaround for changing "ScriptLanguage" of onEntry action for Business Rule Task:
switch a "Task Type" to Script Task, change ScriptLanguage, switch back to Business Rule Task.
