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 of problem:

Subscription Manager GUI displays the following error dialogue when Date field is being set to blank.

'Invalid date format. Please re-enter a valid date. Example: 03/17/2011'

This error dialogue comes up on every operations excluding Close and setting 'data' manually into the date field. Even the dialogue shows up periodically without any operations.

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

subscription-manager-0.95.4-1.el6.i686
subscription-manager-gnome-0.95.4-1.el6.i686
subscription-manager-firstboot-0.95.4-1.el6.i686


How reproducible:
1000%

Steps to Reproduce:
1. System -> Administration -> Red Hat Subscription Manager
2. Register the system and go to All Available Subscriptions tab
3. Delete date from the field and then click somewhere such as Calendar icon or 'Update' button.
  
Actual results:
An error dialogue keeps coming up.

Expected results:
You can click Calendar to set new date.

Additional info:

Proposed fix is to on error, reset the date picker's date field to the last valid date that was entered. Since the date is valid again, the user can now click the calendar button to select a valid date.


Patch is ready, if this solution is reasonable.

Fixed in:

master 57a82070e778b8b8eba71bc87fd8be5673134f9c
