Github user bhaisaab commented on the pull request: https://github.com/apache/cloudstack/pull/740#issuecomment-134508369 @karuturi the sharedFunctions.js defines a global pagesize (fixed to value 20) See in the screenshot; the listTemplates call does not call the API with a page, pagesize - this causes the infinite scroll to flood the list every time to drag it if the number of zones exceed what could fit in that table view. This patch fixes that.
