Drag and Drop Error

[carlosrg_]

I used the following script to change the metadata Drag and Drop:

ContentView create

And got the following error:

/ layouts / layout_listing_ajax_template.xhtml 146.59 @ value = "# {value.data ['dc'] ['title']}": Target Unreachable, 'data' returned null on 'java.util.HashMap'

Are you sure you don't override this template in your own project. Because I don't see in Nuxeo source code {value.data ['dc'] ['title']}

in this template (See github)

[Anahide_Tchertc]

This expression is not really in this template, but it's referenced there by the layout system (it's generated from widget configuration)
