OutOfMemoryError in JBPM3.2.1
The following taskform code works in JBPM3.2.GA.
But when running in JBPM 3.2.1, it causes OutOfMemoryError. By testing, I found that if I change <jbpm:dataform columns="2"> to <jbpm:dataform>, it will work well in both JBPM3.2.GA and JBPM3.2.1.
How can this error be fixed?
