RES: [flexcoders] ViewHelper and Cairngorm

Title: Mensagem
Hello !
 
My problem is to update a view after an execution of a Command. For example, I would like to update
DataGrid rows after performing a new database query. So, I was taking I look on Cairngorm source
code and I found the following comments for ViewHelper.as:
 
 * In order to carry out their function, Command classes will require
 * to both interrogate and update the view.  Prior to performing any
 * business logic, the Command class may require to fetch values that
 * have been set on the view; following completion of any business logic,
 * the final task often to be performed of a Command class is to update
 * the View (user interface) with any results returned, or perhaps to
 * switch the View entirely (to a different screen).
 
So, I think this pattern can help me to solve this question. Am I right ? Is it the best approuch
for updating my view ?
 
P.S: What about Cairngorm Framework compatibility in Flex 2.0 platform ? Any news ?
 
Thanks to Stanislav for his sample also !
 
Regards,
Michel.

Michel,
 
Why do YOU want to use a view helper ?  What is the business problem you are trying to solve ?  What is the technical challenge ?  Design patterns are solutions to problems.  Do you have the right problem for a ViewHelper to solve ?
 
Tell us what you're trying to do ?  Who knows, maybe the ModelLocator would better suit your task.
 
Steven
