Description

I have observed that sometimes hitting the relations tab will return a 404 error from Tomcat. This seems to happen most frequently when it is pressed within 30 seconds of creating/uploading a new file in Nuxeo. The error looks like this:

HTTP Status 404 - /nuxeo/nxdoc/MyRepo/8e5fc580-ddad-4942-b1a7-1b200982bf50/view_documents

type Status report

message /nuxeo/nxdoc/MyRepo/8e5fc580-ddad-4942-b1a7-1b200982bf50/view_documents

description The requested resource (/nuxeo/nxdoc/MyRepo/8e5fc580-ddad-4942-b1a7-1b200982bf50/view_documents) is not available.
Apache Tomcat/5.5.20

Clicking reload when this appears will usually cause the correct thing to be displayed.

I haven't been able to reproduce this problem.
The 404 error is displayed when the error is too grave or happens in a phase where the application cannot display the error page, so it may be useful to get a traceback from the logs.

I'm having some difficulties duplicating this due to ~~NXP-1586~~. I caused the system to generate an exception from the relations tab, but due to that bug I'm not sure if this is the same condition that caused the 404. I am attaching the server.log anyway.

Creating a file without content worked around ~~NXP-1586~~. I did so and got this error when I clicked on Relations:

HTTP Status 404 - /nuxeo/nxdoc/MyRepo/9c14bd9e-128c-4887-ae39-d6fef5e7f150/view_documents

type Status report

The attached exception corresponds. Pressing Reload caused the correct page to be displayed.

Connection was sometimes lost (it was stored in the graph) ; a new one is now created at each call.
Clicking the reload button made it work because connection was destroyed and rebuilt when catching an error.
