authorityContainer Properties in Alfresco 3c

mark_smithson

I have found a potential problem with 3c.

I created a new user and group in Alfresco and added the new user to the new group.

Given this webscript:

// locate person for username
var person = people.getPerson(url.extension);
model.groups = people.getContainerGroups(person);
‍‍‍‍‍

and this template

<?xml version="1.0" encoding="UTF-8"?>
<groups>
      <#list 0..groups?size - 1 as x>
        <group>${groups[x].properties.name}</group>
      </#list>
 </groups>

‍‍‍‍‍‍‍‍‍

I get this error:

org.alfresco.service.cmr.repository.TemplateException - Error during processing of the template 'get(properties) failed on instance of org.alfresco.repo.template.TemplateNode'. Please contact your system administrator.

It seems to happen when accessing properties. If the user is only a member of the built in EMAIL_CONTRIBUTORS group this error does not occur.

This was not a problem on Labs 3b. Is this a bug, or have I missed something obvious?

Thanks

I have managed to work around this issue by accessing the properties I needed in the javascript and putting them into the model.

So it seems there is only a problem when trying to access the properties via Freemarker and seems to be caused by the PropertyConverter trying to update a read only list. There seem to be no changes in the code for these classes in SVN, but perhaps the collection has been made read only in a labs 3c change?

If someone can confirm if this a bug, rather than me being daft, I will log a JIRA case.

I'm sorry for possible missunderstanding. I'm new to Alfresco…
But it seems i have similar problem using Labs 3 (last distrib available)

Me defined a property as follows:

<property name="oid:extLinkList">
               <type>d:text</type>
               <multiple>true</multiple>
               <index enabled="true">
                  <atomic>true</atomic>
                  <stored>true</stored>
                  <tokenised>true</tokenised>
               </index>
            </property>
‍‍‍‍‍‍‍‍‍‍

And trying to access it in template

<#if space?exists>

   <#if space.properties[oid:extLinkList]?exists>  <table>
        
      <#list space.properties[oid:extLinkList] as links> 
              <#assign url=   links?substring( links?index_of("=")  )?trim   >
               <#assign des=   links?substring(0, links?index_of("=")  )?trim   >    
               <tr><td> <a target="new" href=" ${url}l">${des}</a> </td> </tr>
         </#list>
         </table>
   </#if>

 <#else> No ext links:
 </#if>‍‍‍‍‍‍‍‍‍‍‍‍‍‍

That's what i get in Tomcat log
get(properties) failed on instance of org.alfresco.repo.template.TemplateNode

Even an attempt to get a list of properties of space gives the same result.

Is it a bug or something else?
