Re-reading your email Kamath I can see you have already been advised on this approach. Perhaps if the non-primitive properties used for the display class were only initialised to a value by their setters the memory issue would be not relevant, and you would already have the names of the properties for the include/exclude parameter of the grid by taking them from the query.

But i think that will be waste of memory since, I have 50 column names from col1,col2,.. col50. Consider the situation where only one column is select by query, the object created will use the storage for all 50 columns where as only 1 is actually useful. so i wanted to know, if i can use beanmodel to add the columns dynamically at runtime. -- View this message in context: http://tapestry.1045711.n5.nabble.com/Creating-Grid-component-at-runtime-tp2 847820p2854386.html Sent from the Tapestry - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
