The Flex UI does not display actions correctly, when using either the original 6.5.0 SDK or later Flings. Specifically, categories don't seem to work at all, and if a large number of actions are present, they are repeated on cascaded menus. This severely impacts the usability of our plugin with the Flex UI.
This issue seems to occur with all versions of the Flex client (6.5.0 RTM, 6.5.0d and 6.5U1). I noticed that the ActionMenuItemSpec in the samples has changed in the latest Fling (to remove the label and icon fields), but applying this change to our plugin has made no difference to the issue.
Is this a known issue? Is there any workaround for this, or way to improve the display of the menus in the Flex client? If not, is it possible to show a different action menu in Flex mode that might at least allow us to reorder/remove entries to try to improve usability whilst maintaining full functionality for HTML client?
I've attached a modified "plugin.xml" for the "chassis-b" sample in the "6.5.0-6094542" Fling SDK which demonstrates the issue, and screenshots of how it appears with the HTML and Flex clients. Note that in the Flex client, no categories are used, and the first actions (Edit, Remove, and Other Actions to "4A" appear twice, and a third-level cascading menu appears called "More Uncategorized Actions" which consumes more screen space unnecessarily). In the HTML client, it appears correctly (Other Actions/Other Actions2 in a category, then Other Actions 3, 4, 5 grouped in their own categories, then Other Action 6 at the top level).
