Subject RE: RSS actions - possible bug when changing contents of feed
Date Sun, 01 Feb 2009 16:37:10 GMT
Vassil found that the cause looks like it is a known Scala bug:
This is the exception:

Twitter let me know you were working on the actions and also that Richard
had set up a recent build on Stax.  I've been keeping an eye on it for the
last week or so :-)

I don't have an environment set up right now that would let me run trunk, so
the feeds are:

The Pipes feed I'm currently trying to use (the one where I changed the
format of the title after it had been set up as an action) is

The Pipes feed that is the same as the original feed that worked once is

You should be able to access both of them since they are published.

Thanks for looking into this!
