RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Jan Pazdziora 2010-05-24 11:29:45 UTC 
Description of problem:

While trying to find a way to implement RHN register part of firstboot, I came across a problem that ModuleSet modules did not show the screens of its modules, but started with the Welcome page again.

Version-Release number of selected component (if applicable):

# rpm -q firstboot
firstboot-1.110.3-1.el6.i686

How reproducible:

Deterministic.

Steps to Reproduce:
1. Have firstboot on RHEL 6 (and Fedora 12).
2. Create ModuleSet module.
3. Try to hit Forward to get to it.
  
Actual results:

Once you hit the moduleset, the first module screen is shown again.

Expected results:

Forward should just walk through the screens of modules of that moduleset.

Comment 1 Jan Pazdziora 2010-05-24 11:30:25 UTC 
If we decide to implement RHN Register part of firstboot for RHEL 6 using the ModuleSets, this bugzilla will become a Beta 2 blocker.
Comment 2 Jan Pazdziora 2010-05-24 11:31:06 UTC 
The following patch seems to fix the problem and makes walking through the pages working:

However, this patch breaks that sidebar arrow.

In Fedora 12, the arrow is there just fine, even with this patch.
Comment 4 Jan Pazdziora 2010-05-24 11:33:12 UTC 
Actually, the sidebar arrow brakage seems to be kinda random in RHEL 6, sometimes it works and sometimes it does not.
Comment 5 Jan Pazdziora 2010-05-24 11:35:36 UTC 
Please note that if you set priority = 0 in your moduleset module, running firstboot will still fail, with

firstboot 1.110 exception report
Traceback (most recent call last):

Comment 7 Jan Pazdziora 2010-05-25 11:14:02 UTC 
Another bug in the firstboot code: if the number of modules in your moduleset it greater than the number of the top level modules, stepping to the moduleset shows exception window with

firstboot 1.110.3 exception report

Comment 8 Jan Pazdziora 2010-05-25 11:15:58 UTC 
The following patch is needed to fix the problem:

-        for i in range(len(self.moduleList)):

             (alignment, label) = self.sidebar.get_children()[i].get_children()
             pix = alignment.get_children()[0]
 

In short, the self.moduleList now (correctly, with the patch from comment 2) points to the list of modules in the moduleset, not to the list of top level modules.

That's why we will just loop over the sidebar children because that's what we essentially care about anyway.

Comment 15 releng-rhel@redhat.com 2010-07-02 20:51:11 UTC 
Red Hat Enterprise Linux Beta 2 is now available and should resolve
the problem described in this bug report. This report is therefore being closed
with a resolution of CURRENTRELEASE. You may reopen this bug report if the
solution does not work for you.
