How can the message from Seam.AddInfoMessage be displayed?
If I use the operations
Seam.AddErrorMessage in a chain then the message is not displayed. Do I have to signal a state or is there another missing configuration?
This is a bug in the user interface of Nuxeo. The message is displayed in the left bottom corner of the browser window. If you use Google Chrome and your mouse pointer is over a link (e.g. an action button from Nuxeo) then this is the place where Google Chrome shows the address/target of the link information. The address information always overlaps the message shown by Nuxeo.
So the operations work but the web interface has a small usability bug.
Do you need more informations? I can provide the complete configuration if necessary (e.g. -type.xml, -ui-type.xml, *-actions.xml).
