[vijayakumar_kb]

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"

vijayakumar_kb - what product are you using, SmartClient or SmartGWT? You posted in the SmartGWT forum, but the version string is not from SmartGWT.
