    Default Tree Panel throwing InternalId is null error

    Tree Panel throwing InternalId is null error


    Hi ,

    I am using a Tree Grid in extjs 4. Getting the following error 'InternalId is null or not an object ' and the page freezes,when I expand some of the nodes of the tree. This error is occuring only on IE . There is no error thrown on mozilla firefox or chrome.

    The JSON String containing data is valid and is escaped..

    Why could this be happening ? One observation is that this error is seen when the child nodes of the node being expanded have some special characters in their data like '+', ':' etc

    Any help to avoid this is great

    Thanks and Regards,
    Namratha

    I would definitely suggest upgrading to 4.1.1
