Dynamic configuration for ActionHandler

[greeneagle]

Hello,

is ist possible to configure an ActionHandler dynamically? More precisely I want to do something like this:

.
.
.
<node>
 <event type='node-enter'>
 <script>
 <expression>
 myVar="I am a variable";
 </expression>
 <variable name='myVar' access='write' />
 </script>
 <action class='MyAction'>
 <text>#{myVar}</text>
 </action>
 </event>
 <transition to='end'/>
</node>
.
.
.

Means I want to configure the parameter 'text' of my ActionHandler-object with the value of the variable I set before in the script-tag.
Unfortunately this approach does not work - the synthax is not valid in this context.
Is there any possibility to get the desired behaviour?

Thanks in advance,

Michael

Hi,
most likely the scope of the script variables is destroyed after the script is terminated, i guess you have to store the variables in the process instance somehow and then access them in the execute() method of the action with something like (not tested):

public void execute(ExecutionContext executionContext) throws Exception {
 ContextInstance contextInstance = executionContext.getContextInstance();
 Token token = executionContext.getToken();
 Object element = contextInstance.getVariable("myVar", token);
 [...]

there is also a nice proxy class for having spring configured actions in jBPM at:

I'm not even sure the script and action run in a pre-determined order.... might be that they do now 'by accident' but without promoting this to 'by design' it might be lost in a new release
