I've got a patch. All tests passed. But I think we need a new test for circular referencing regression.

It seems that the test "CircularRelationshipTests" could not catch this bug.

I'm not sure the patch is correct. Surely isBidirectional() should not be returning true in this case? I'm sure it's a uni-directional relationship. I'll have a look at why Grails considers the relationship to be bidirectional.

Hi, I'm new to grails and patching, but I need this patch in order to get the example Grails code from Groovy in Action to run.

I'n order to apply this patch, do I need to have the source code checked out from subversion? WHere can I read more about patching from Jira? My search came up empty. Also, how can I check out from the grails repos?

Thanks

You have two options:

Get a 1.0.3-SNAPSHOT from the build server, or check out the latest code from subversion
Download the 1.0.2 source code from the Grails website and apply the patch (for example: patch -p0 < grails_2689.patch )

Information on checking the source code out of subversion can be found here.

The snapshots page is empty at http://snapshots.dist.codehaus.org/grails/

Any idea when 1.0.3 is coming out? I'm not too comfortable using code I've patched and build myself.

No, sorry. The main developers are really tied up at the moment, unfortunately. I would seriously consider getting hold of one of the 1.0.3 snapshots. Just follow the instructions here:

http://www.grails.org/Download

under "Grails 1.1 Development Build".
