    [CLOSED] Error when binding KeyMap to not active Panel in TabPanel

    I get an error with the following code. The problem seems to be that you can't bind a KeyMap to a not active Panel in a TabPanel.

    By default, non active tabs are not rendered. They are rendered when first time activated.

    To change this behavior you can set up
    for the TabPanel.

    Though it will cause all tabs to be rendered initially - it can decrease the application performance. So, I would suggest to create KeyMaps on the fly via JavaScript within tabs AfterRender listener.

    Also, please read the following related thread:

    DeferedRender="false" will work for me.
