Setting the title with metadata extraction

Hi all,I have metadata extraction setup in a WCM project, which amongst other things is taking a title out of the XML on a document and placing it into the cm:title property of the node. However, this doesn't work when content is initially created, and cm:title gets overwritten with the name of the

I have a similar problem.

As for the content extraction, you may want to look into "Overwrite Policies". These allow you define their behaviour when a property has already been set:

There might also be another reason, at least for WebDAV. In

org.alfresco.repo.webdav.PutMethod#executeImpl()‍

, the properties ContentModel.PROP_TITLE and ContentModel.PROP_DESCRIPTION are set, regardless of any previous values that might have been assigned.

The only solution I can think of is to patch that that class in order to prevent the behaviour outlined above. Alfresco should definitely fix this.

Btw., I'm on version 2.1.1.

We're using the EAGER policy, since we need to overwrite the object values if the user changes the form data. On subsequent saves, the cm:title is overwritten correctly - it's just the first time the content is created that causes a problem.

This is on Alfresco 2.2.0.
