YUM groupinstall question

[Eran Ben Natan]

Hi,

I am using RPM to deploy our product to customers, and I want to start using YUM.
I created a test repository with group and it works fine, expect one issue:
Suppose I have the following RPMs, created with attached spec:
foo-1.0-1.x86_64.rpm
foo-2.0-1.x86_64.rpm
bar-1.0-1.x86_64.rpm
bar-2.0-1.x86_64.rpm

And I have the group xml below.
When I run yum groupinstall Test, it installs foo-2.0, bar-2.0, as expected.
But when I run yum groupinstall 'Test 1.0', I get:  No packages in any requested group available to install or update
yum groupinfo 'Test 1.0' shows foo-1.0 and bar-1.0, and if I run yum install foo-1.0 it works.
In  the YUM man page for groupinstall it states:  this works as if you'd taken each of those package names and put them on the command line for a "yum install" command

Does anyone knows what is the reason for this behavior, or what is the best practice to allow group install to specific version?

Thanks, Eran.
