Duplicate entries for the same Heat Stack on Horizon

[Visnusaran Murugan]

Created a single sample Wordpress Heat stack through CLI and Horizon show multiple entries of the same stack. Screenshot attached.

Data from heat-api:

{"stacks":[{"description":"Heat WordPress template to support F20, using only Heat OpenStack-native resource types, and without the requirement for heat-cfntools in the image.

Issue with the way calculation is done for pagination in heatclient, . Moving from horizon.

Just hit this in Horizon, pretty shocking at first! Thank you for looking into it.

This looks like a duplicate of bug #1322097.

Can you confirm that you have the latest release of python-heatclient 0.2.9?

Also what version of Horizon and Heat are you running? This may only be an issue with a recent Horizon on a Havana Heat.

Hi Steve,

Yeah its a duplicate. Also the pagination code in heatclient assumes that it gets complete stack-list and used that info to iterate. This works only if --limit parameter is not passed. I have a fix which with does not work on total stack-size. Will mark this as defect duplicate.

I am using a devstack installation. Code is as of 26th June 2014 (master).
