For my Tapestry / jBPM integration project, I stumble onto this problem:

JbpmContext contextA = JbpmConfiguration.getContext();
JbpmContext contextB = JbpmConfiguration.getContext();

ProcessInstance instance = contextA.createNewProcess(name);

------------> bluhhh...

This happens because I would like to have a context available during all the steps of the render of each page.

When I transfers from page A to page B, page B is created and startes the rendering process (i.e. contextB is created) before I have created the new ProcessInstance. But creating a second context makes the first one behave "funny" and fail the creation (return id=0).

Should I have shorter spanned contexts: one for every component I need to render?
