Seam + JBPM: Accessing variables via <h:inputText>

[jsvegas2]

Hi,

I'm new to Seam and JBPM and I have a beginner's question about accessing process variables:

When I change e.g. the value of the task.name:
<h:inputText value="#{task.name}" style="width: 300" />

and I klick my update-button:
<h:commandButton value="Update Items" action="update"/>

everthing works fine and the new name is saved.

But when I try the same thing with a Variable:

<h:inputText value="#{task.variables['testVar']}" />

...that was earlier outjected to the process, no changes are saved. That means, the <inputText.../> shows the outjected value, but it can't change the value.

How can I do this?

Thank You!

I assume task.variables is a copy of the variables and changes don't affect the underlying data structure.
