Hey people,

i found the Cascading Constraints from Jean Barmash (http://blogs.alfresco.com/wp/jbarmash/2008/08/08/dynamic-data-driven-drop-downs-for-list-properties/)and need them for my current project. What i wanna do is to generate the List of values out of spaces that are in my customer folder. My problem is now to set the Lucene query for the constraint.

<constraint name=”my:customConstraint”
type=”org.alfresco.sample.constraints.LuceneSearchBasedListConstraint” >
<parameter name=”query”>
<value> TYPE:”{http://www.alfresco.org/model/content/1.0}folder” AND@\http://www.alfresco.org/model/content/1.0\}name:'Customer"
</value>
</parameter>
</constraint>

I get following error in the log file:

I think it is related to my Lucene query not working. Can some1 please help me.

Does the query work in the Node Browser?  Make sure it returns what you need before putting it into the config - from the snippet you provided it looks like you need a space after AND. 

TYPE:”{http://www.alfresco.org/model/content/1.0}folder” AND@\http://www.alfresco.org/model/content/1.0\}name:'Customer"
