    Default error when opening a Library

    A global handle map entry is simultaneously being assigned to 2 objects.

    Has anyone experienced this error?
    This happen when the user opens the custom library. It does not appear to be affecting the nodes running. Just errors when opening the graph.

    It says the following for each node that it has an issue with. And they all seem to be DBQuery or JDBCQuery nodes of some kind.

    There appears to be a problem.
    A global handle map entry is simultaneously being assigned to 2 objects.
    Handle is 5303d89648164c52
    Old object is node wdm_prod_clob
    Old object in file C:\Users\CDC060376.000\Documents\_lavastorm\wholes ale\brg\MyLibrary.brg
    New object is node wdm_prod_clob
    New object in file C:\Users\CDC060376.000\Documents\_lavastorm\wholes ale\brg\MyLibrary.brg
    BugCheck in method AssignHandle

    Default

    One of the main times when I see this happen is if you have your own graph set as a library to itself.
    Close BRE and do not save the file.
    Edit the BRG with some text editor such as notepad and look at the top few lines.. you don't want any of the "baselib:" lines to reference the same BRG that you have open. If they do, just delete the reference.

    ===
    The other time this happens is if you have two nodes with with the identical HANDLEs in separate libraries. This can easily happen if you copy/paste a library node from one library graph to another, and then have a graph which opens both of the libraries at once.

    If you ever want to duplicate a library node into a different library, you should use the keystroke sequence:
    Copy / Paste / Cut / switch BRGs / Paste

    If you already have this situation in a library and can identify which node it is, then use Copy/Paste to generate a clone of the offending node (which gives you a new Handle) and then DELETE the original copy.
