Question

So for my project, we have some javascript code running as a rule within the Alfresco repository. So whenever a new document comes into a certain space, a new folder is dynamically created and that document is moved into that newly created space. Additionally, whenever a new folder is created, a property is updated like so for the document (expect caseID is actually a dynamically generated value based on a sequence in our database):

//Add caseID as a property of the folder
var props = new Array(1);
props["wf:caseIDNum"] = caseID;
var newAspect = newNewSpaceName.addAspect("wf:caseID",props);

However, now we want to be able to reference that newly created aspect/property during the course of our workflow in our share-workflow-form-config-.xml file so that it can be passed as a parameter to our control template. That is, currently we have:

<field id="wf:submitCode" label-id="workflow.field.outcome" set="actions">
                  <control template="/org/alfresco/components/form/controls/workflow/custom-activiti-transitions.ftl"/>
               </field>

But what we want is something like the below:

<field id="wf:submitCode" label-id="workflow.field.outcome" set="actions">
                  <control template="/org/alfresco/components/form/controls/workflow/custom-activiti-transitions.ftl">
                     <control-param name="caseID">wf:caseIDNum</control-param>
                  </control>
               </field>

So my question is, is that the proper syntax to pass a variable/property from the workflow model to the FTL file via the control param?

Edit (10/25/12) –

So based on the help given here, I tried to modify my ftl page like so…

custom-activiti-transitions.ftl:

<#assign caseID = "">
<#if field.control.params.caseID??>
    <#assign caseID = field.control.params.caseID>
<#else>
    <#assign caseID = null>
</#if>

<style type="text/css">

.button {
border: 1px solid #666;
background: #DCDCDC;
padding: 5px;
color: #333;
text-shadow: 1px 1px #fff;
-moz-border-radius: 5px;
-webkit-border-radius: 5px
border-radius: 5px;
cursor: pointer;
-moz-box-shadow: 1px 1px 2px rgba(0,0,0,0.3);
-webkit-box-shadow: 1px 1px 2px rgba(0,0,0,0.3);
box-shadow: 1px 1px 2px rgba(0,0,0,0.3);
}
a.button:hover {
background: #bbb;
color: #000;
text-shadow: 1px 1px #eee;
}

a.button:active {
position: relative;
top: 1px;
left: 1px;
-moz-box-shadow: none;
-webkit-box-shadow: none;
box-shadow: none;
}

</style>

<a class="button" href="#" onClick="MyWindow=window.open('http://localhost:8080/alfresco/faces/jsp/custom/CodeSelector.jsp?caseID=${caseID}','My Window','toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no,width=600,height=300'); return false;" style="text-decoration:none" target="_blank"><span>Add Codes</span></a>

And in my share-workflow-form-config.xml, I changed any instance of:

<field id="wf:submitCode" label-id="workflow.field.outcome" set="actions">
 <control template="/org/alfresco/components/form/controls/workflow/custom-activiti-transitions.ftl">
 </control>
</field>

to…

<field id="wf:submitCode" label-id="workflow.field.outcome" set="actions">
 <control template="/org/alfresco/components/form/controls/workflow/custom-activiti-transitions.ftl">
  <control-param name="caseID">wf:caseIDNum</control-param>
 </control>
</field>

My problem is that in the share-workflow-form-config.xml where I specify the control-param, I can get it to pass in a hard coded value like “30”. However, when I try to get the value of the workflow property like wf:caseIDNum, it returns the actual string in the parameter like:

http://localhost:8080/alfresco/faces/jsp/custom/CodeSelector.jsp?caseID=wfcaseIDNum

as opposed to the actual value for the property, i.e. “30”.

Any ideas on what I could be doing wrong?

It’s exactly as skuro said and you’re not doing this rightly.

Very simple your config is correct but your ftl lacks some logic.

Why will you first check on <#if field.control.params.caseID??>
And then not assign it?

It should be:

<#if field.control.params.caseID??>
   <#assign caseID = field.control.params.caseID>
<#else>
   <#assign caseID = 1>
</#if>

There is no need of a context or args or something.

Take a look at the default ones like /org/alfresco/components/form/controls/textarea.ftl

—– UPDATE —–

So how can one access another field in this template.
So we’ve got another field “wf:caseIDNum” and we want to access that one.

You could use the following hacky mechanism to get it

${form.fields["prop_" + caseID?replace(":","_")].value}

in the form.fields all the current form properties are stored.

BTW don’t forget to show the “wf:caseIDNum” and the hidden.ftl template or else the property won’t be populated in the fields object ;).
