Association control and startLocation

orichaud

Hi,
In my form, I have a field which refers to an association. When using the picker, I I need to select documents in a specific space and for this I need to change the parentNodeRef parameter.
I read the wiki (see http://wiki.alfresco.com/wiki/Forms#association.ftl and found that I can define the startLocation parameter. I passed an XPath expression. But it had no effect. Unfortunately, looking at association.ftl, this is hardcoded to "alfreco://company/home".

Finally, I have started to provide a custom form as described here: http://wiki.alfresco.com/wiki/Forms_Examples#Providing_A_Custom_Form_Template. I copied association.ftl and tried to change the parentNodeRef. But I was not successful and an Xpath expression like

/app:company_home/st:sites/cm:acme‍

led to an error.
It seems that workspace://<ANY NODE REF> works, but I cannot hard code the reference and must rely on a logical name, thus an expression. I wonder which service I could invoke to convert the xpath expression into a valid node reference.

Any help would be appreciated.

Regards.

Olivier

…led to an error.

It would perhaps be useful if you described the error in more detail.

Thanks,

In my share-config-custom.xml, I define the appearance of the field:

   <config evaluator="node-type" condition="ahp:photo">
      <forms>
         <form>
…
            <appearance>
…
               <field id="ahp:copyrightDocument" set="copyright-set">
                  <control template="/org/alfresco/components/form/controls/ahp_association.ftl">
                     <control-param name="showTargetLink">true</control-param>
                     <!–<control-param name="startLocation">alfresco://company/home/sites</control-param>–>
                     <control-param name="startLocation">/app:company_home/st:sites/cm:acme</control-param>
                  </control>
               </field>

The ahp_association?ftl control is a simple modification of association.ftl where I modified the parentNodeRef paramaters:

parentNodeRef: "${field.control.params.startLocation}",
‍‍‍

Now, when I choose the edition mode and want to edit the association, I can see in the selector:

org.alfresco.error.AlfrescoRuntimeException: 10150001 Failed to execute search: ID:app\:company_home\://st\:sites/cm\:acme
‍‍‍

With firebug, I can see that

http://localhost:8080/share/proxy/alfresco/api/forms/picker/node//app:company_home/st:sites/cm:acme/children?selectableType=cm:content&searchTerm=&size=100

got the following response:

    "code" : 500,
    "name" : "Internal Error",

  },  
  
  "message" : "org.alfresco.error.AlfrescoRuntimeException: 10150001 Failed to execute search: ID:app\\:company_home\\:\/\/st\\:sites\/cm\\:acme",
