Import javascript into workflow

nparry — Fri, 06 Jul 2007 18:20:11 GMT

When writing a workflow, can you import a javascript file from the repository into the workflow instead of actually writing it all in the xml file? I tried something like this, but it did not work:<script> <import resource="/Company Home/Data Dictionary/Scripts/someJS.js"></script&

In theory, yes. I haven't attempted this myself, so can't be sure.

Can you clarify that your code is inside:

<action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
  <script>
      …
  </script>
</action>

What sort of error did you see?

At first I tried this:


<action name="notHiredAction" class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
   <!– This is where the javascript should be imported –>
   <script>
      <import resource="/Company Home/Data Dictionary/Scripts/someJS.js"> 
   </script>
</action> 
‍‍‍‍‍‍‍‍

And I got an error during deployment that said the "import" tag needed an end tag. So, I added a forward slash onto the end of the tag:


<action name="notHiredAction" class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
   <!– This is where the javascript should be imported –>
   <script>
      <import resource="/Company Home/Data Dictionary/Scripts/someJS.js" /> 
   </script>
</action> 
‍‍‍‍‍‍‍‍

I then got the error from graph.def.GraphElement:


action threw exception: Script expression has not been provided.
‍‍‍

It looks like it's just not evaluating the "import" tag. That's why I thought it might just be a syntax problem….

Wrap your script in a CDATA block e.g.

        <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
            <script>
              <expression>
                 <![CDATA[                 
                    <import resource="/Company Home/Data Dictionary/Scripts/test return value.js">
                 ]]>
              </expression>
              <variable name="theresult" access="write" />
            </script>
         </action>‍‍‍‍‍‍‍‍‍‍
