[jboss-user] [JBoss jBPM] - How to set task instance variables with <h:inputText/> ?

[appendix]

Hi,

I wonder if there is a way to set task instance variables directly from the frontend (build upon JSF/Seam)?

I've tried 
<h:inputText value="#{taskInstance.variables['var1']}"/> 

to set var1 into the context of the current taskInstance.

Using this expression in an <h:outputText /> tag with an already set instance variable works fine, because taskInstance.getVariables() returns a map, which can be indexed like that, but is there a easy way to set the variable? 
The API only shows taskInstance.setVariable(name, value) and this can't be used in JSF expression language.

Thanks for any pointers,

   Kurt
