Generic Web named expressions ({Id}.+?) - are these supported? [message #55555]

Documentation for Generic Connector at
http://wiki.eclipse.org/index.php/Mylyn_User_Guide#Generic_W eb_Repository_Connector
indicates that I can define expressions like this:

Note: Query Pattern field should be a regexp with 1st matching group on
Issue ID and 2nd on Issue Description. Alternatively, you could use named
matching groups: ({Id}.+?), ({Description}.+?), ({Status}.+?), ({Owner}.+?)
and ({Type}.+?), then they can appear in query regexp in an arbitrary order.
The second option requires build 2.0.0v20070717 or later.

I tried to build pattern using the alternat form ... ({Id}.+?) ... but I get
expression errors.

I'm using Ganymede, and all mylyn related plugin jars have version numbers
of 3. something with build dates 2008...

The generic web plugin is
org.eclipse.mylyn.web.tasks_3.0.1.v20080721-2100-e3x.jar.

Question: Is this feature for naming the patterns supported, or possibly the
documentation is wrong?

The error you are seeing may be caused by a regression in Mylyn 3.0 that has
been reported here:

243131: [web connector] named regex groups don't work with 3.4
https://bugs.eclipse.org/bugs/show_bug.cgi?id=243131

Please comment on the bug report with the expression that is failing for
you.

Thanks.

I have added a comment to the bug.

What I find is that {Id} causes the parsing error: null pointer. Any of the
other keywords cause a message that taskId and summary must be specified
(see bug for exact message).

Also, I believe that if using named matching groups that it is necessary for
all matching groups to be named. If this is a rule, the NOTE regarding the
alternate form using named matching groups should be updated.

Steffen,
Have installed the weekly build and the named expressions are working just
fine.

Thanks
Michael
