Why can't I have more writeable variables?

I am using v2.1.

The following syntax throws an exception. It expects an other tag inside <script>.

<action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
&nbsp; <script>
&nbsp;&nbsp;&nbsp; // some alfresco javascript
&nbsp; </script>
</action>‍‍‍‍‍

But the following syntax works.

<action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
&nbsp; <script>
&nbsp;&nbsp;&nbsp;&nbsp; <expression>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // some alfresco javascript
&nbsp;&nbsp;&nbsp;&nbsp; </expression>
&nbsp;&nbsp;&nbsp;&nbsp; <variable name="passedInValue" access="read"/>
&nbsp;&nbsp;&nbsp;&nbsp; <variable name="passedOutValue" access="write"/>
&nbsp; </script>
</action>‍‍‍‍‍‍‍‍‍

But I can have only one writeable variable. Otherwise it throws an exception.

In lot of examples I saw the first syntax and the second one (with multiple writeable variable) were used. But why can't I use that syntax.

adhoc_processdefinition.xml which uses the first syntax works without any problem But my custom process definitions does not work .

Thanks & Regards,

The first form is definitely valid - as you it's used in the out-of-the-box workflows.  What script do you have in your <script> tags?  You may need to wrap it in a CDATA block.

You can only have one writable variable because that's the way it is right now.  We can support more, but it requires a slight change to how we've integrated the javascript engine.
