Comment 1 Steffen Pingel

Can you try validating the repository from the Task Repositories view?

Comment 2 LI Daobing

2010-04-14 23:41:21 EDT

Yes, I can validate the trac repos, and this bug still happens after I validate it.

Comment 3 Steffen Pingel

2010-04-18 15:28:30 EDT

Can you check what is selected under Additional Settings > Access Type on the Trac repository settings page?

Comment 4 LI Daobing

2010-04-18 22:01:23 EDT

It's "Automatic", After I change it to "XML-RPC", it re-works.

Thanks.

Comment 5 Steffen Pingel

2010-05-19 22:21:03 EDT

I have improved the messaging for displaying verification results and verified that the dialog does not enable finish unless an access mode is selected. The error handling should still be improved in case the repositories file is corrupted and the repository does not have a valid version property.

Comment 6 Steffen Pingel

2011-09-16 12:54:59 EDT

I have committed a change that avoids the exception and falls back to XML-RPC automatically if the information is not available. This should be correct in most cases but can cause failure if the repository only supports the web mode. Users can easily recover through validating the repository.
