ValueError: can only parse strings

How can i resolve this bug??

Probably the file of the XML view does not exist (or it is empty).

Either the filename in the “name” field of the view, or the filename in view/xxxx.xml is wrong.

This post was flagged by the community and is temporarily hidden.

As the message is not clear enough, I filled Issue 9940: Better error message when XML is missing for a view - Tryton issue tracker
