Problem creating tickets with xml-rpc: 'weakly-referenced object no longer exists' while executing 'ticket.create()'

[anonymous]

I've been trying to fix this for a couple of days and I do not know why it may be happening.

Eclipse throws this error

org.apache.xmlrpc.XmlRpcException: 'weakly-referenced object no longer exists' while executing 'ticket.create()'

Are you really using Trac 0.11? We recommend to upgrade to Trac 1.0.x, at least.

Please post trac.log when the error is raised after enabling TracLogging with DEBUG level.

the version 0.11.4 exactly. It is not feasible in the short term to change the version :( I will try to put the log that Trac offers.

It's also not feasible for us to provide support for 0.11.7. The last 0.11.x release was in 2010.

Now it works. I put all the fields of the ticket and .. magic. I don't understand anything, but it works.
