Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

steps to reproduce:
1. Install OS to the boot disk has existing partitions
2. On the 'MANUAL PARTITION' page, select 'RedHat Enterprise Linux Server Linux 7.0 for x86_64 ' has the existing partitions, then click '-' to remove the partitions.
3. A dialog would then appear to prompt to ask the users if will remove all the partitions. Check it, then the error message appears.

Comment 13 Chris Lumens 2012-11-21 16:44:35 UTC 
I am unable to reproduce this using a tree I just built today.  From the looks of your screenshot plus the code involved, I think you would only hit this if everything on the left hand side of the screen were collapsed.  I think that's the case where page is None.

However trying today, with everything collapsed, I do not get the "remove all partitions" checkbox so I think this should be fixed.  Can you test with the next RHEL tree containing something later than anaconda-18.29 and double check?  Thanks.
