This is all the logs have and what it looks like is that the nodes that are my custom content type are note a standard noderef object. I would not have expected this.

I also can get similar behavior by clicking on the Information on the node in the Alfresco web client. The exception that it reports is as follows:

Re: Custom Content Model Causes

rdifrango — Wed, 07 Jan 2009 19:16:24 GMT

I finally figured it out, I wanted to allow for an aspect that had multiple values so I did the following:


            <property name="hhmi:departmentName">
               <type>d:text</type>
               [color=#FF0000][b]<multiple>true</multiple>[/b][/color]
               <constraints>
                  <constraint ref="hhmi:departmentList" />
               </constraints>
            </property>
‍‍‍‍‍‍‍‍‍

Well, we decided that we no longer needed multiple values, I just changed the highlighted line to false and it worked.
