Camunda Expression Evaluation

Hi Thorben,

this might work if I want to evaluate the dateTime function, however I need to dynamically evaluate possible method invocations. Is there any possible solution, using the camunda engine, to evaluate such method invocations which are done via expressions?
Can the engine work with custom invocations such as ${doThis().doThat(1)} which might be declared in the delegates?

Cheers,
Sascha
