timeout

I had forgotten to document the ‘timeout’ feature of the participant expression. It’s documented for OpenWFEja but not for OpenWFEru. This has been fixed.

Until now, the timeout concept in OpenWFEru was limited to the participant expression and the when expression. For OpenWFEru 0.9.11, I’ve implemented a “timeout” expression :

The sequence of participants bravo and charly will timeout after three days. [Johnny] bravo itself will timeout after twenty hours (timeout attribute of the participant expression).

It wraps its child expression with a timeout behaviour.

Somehow the question is : why didn’t I do that in the first place ? No need thus to have an attribute ‘timeout’ for the participant expression… Well, trial and errors and the ‘timeout’ attribute makes for concise process definitions (and it’s backward compatible).

PS 1 – pastie is nice
PS 2 – I’ve written a bit more documentation on expressions and on patterns.
