    export excel + java.lang.String cannot be cast to java.util.Map'

    Hi everyone

    i need to perform export to excel in the listgrid
    but when i do export an error is showing
    "java.lang.String cannot be cast to java.util.Map".

    I am using an arraylist to populate the grid. just inserting
    the bean object to the list and setting the dsresponse..

    also while doing any actions on the page the fetch method is getting called.
    when clicking the export button also the fetch method is gettting called. i am using DMI to perfrom grid fill.

    and using the java call like
    <serverObject lookupStyle="new" className="com.rsw.dibac.bean.MB_LAGINF9"/>

    the version used is "SmartClient_70rc2_Evaluation"

    full stack trace is
    com.isomorphic.servlet.IDACall top-level exception

    There is a workaround, however, this was resolved for 8.0 and you should most likely be evaluating with that version. It's on the download page now.

        I'm interested too. I'm having the same problem using smartgwtpro 2.5 nightly build downloaded 2 days ago

          @sampietrog were you previously working with an older version of SmartClient? If so, then you probably did not correctly install the new product and are still working with parts of the old product. Correct installation instructions are in the SmartClient Reference under "Deploying SmartClient". Be sure to also clear your browser cache.
