Description

during the execution of batch transformation rules, rule specifications are registered in the ruleBase, the activations are executed and then the specifications are disposed. this dispose step can cause a number of problems. For example if the batch transformation consists of a single rule with a large number of different event filters, the rule calls itself recursively, until the break conditions are met (typically the source model is transformed).

The problem here is the following:\ Rule A1\ calls Rule A2 ...\ calls Rule AN

The execution of Rule AN will be finished first, and when this happens, the batch transformation statements disposes Rule A as a whole. due to this A1..AN-1 instances will be inactive (as their rule specification is disposed) resulting in a faulty transformation behavior.
