Can a jBPM condition expression contain input parameters?

[hwt]

Hi,

The jBPM userguide points to the JEE expression language for its condition expressions:

http://java.sun.com/j2ee/1.4/docs/tutorial/doc/JSPIntro7.html

I read the JEE page concerned, but am not able to figure out if it is possible to have a condition expression like:

workflowState.xmlUtil ("/RootElement/SomeElement['someAttribute']") == 5

This allows condition expressions in a workflow process definition to be modified whenever the data supplied to the workflow has undergone a structural change, for example, when the XML document supplied has a new attribute in a new node, without having to write a bean class containing bean.getSomeAttribute().

Does anyone know if such condition expressions are accepted by jBPM? If they are, where can the syntax information be found?

Thanks in advance.
