Re: Creating Grid component at runtime
As advised in the previous reply, i can create a class which contains all the column display only those column names which are present in 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-tp2847820p2854386.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

RE: Creating Grid component at runtime
Can you use a helper class that contains getters for all the possible fields you require, and them dynamically build a comman delimited include (or exclude) string, that you pass to your grid using include/exclude via a page property?

RE: Creating Grid component at runtime
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.

It's only possible to redirect when a request is made. So i was asking, how to redirect to start page from sessionDestroyed method. It's not possible. Instead, create a RequestFilter that checks if the session exists and the user is logged in, then use Redirect.sendRequest() if needed.
