Do you want to show a customised message for the user in Share web application?

I created a new custom content model containing my custom types and associations (type child-associations) and then i created a custom share action that runs a webscript to show this relations in alfresco share.

During the configuration of a node, a user can modify its properties and can associate it with another node that becames its child. Since i have setted the tag duplicate to false, if the user try to associate a duplicate child, the system return an exception message that i want to customize. The exception is of the type "CyclicChildRelationshipException", maybe should i override this type of exception?

A cyclic child relationship has nothing to do with the setting / value of duplicate. It is absolutely forbidden to have a cycle in your data structures. There is no way to override this type of exception without patching / overriding core services or out-of-the-box web scripts. There is also no way to override the exception message since this such a technical error that Alfresco actually embedded the message into the code instead of relying on a translate-able message resource.

Thank you Alex for your reply.
I want to avoid to have cycle in data structure, i want create associations between nodes but i don't want they create a cycle. The only way that i found to do this is to create the child-association as i write above. If there is another way, i appreciate any suggests. Thanks.
