CustomLayouts make application UI work slow / buggy

[Jani Laakso]

Inspect if this affects upgrading => tell Marko (documentation) if so

Try UpgradingSample? layout issues after login Reproduce

• login ISSUE: this takes too much time
• click menu items multiple times ISSUE: "production" layout flashes ISSUE: sometimes two elements of menu seem to be selected (rendered blue)
• now logout ISSUE: this also takes too much time

Tested with FF2.0.0.9 (mac)

Same with CustomLayoutDemo?

• click menus ISSUE: header is updated but body area is not (requires hitting "refresh" button) ISSUE: sometimes two elements of menu seem to be selected (rendered blue)

At leas some of these issues are IPanel related...

[Matti Tahvonen]

CustomLayout? body updating issues resolved in [2764]. Menus selection is most likely a bug in tree.

[Matti Tahvonen]

in [2766] fixed tree selection indication problems

[Matti Tahvonen]

in [2767] some small changes to CustomLayoutDemo?

[Matti Tahvonen]

after ITree refactoring everything seems to work fine in this demo.
