Thanks Wally. It worked. I don't know where I was missing. I started from the
same because with one panel I tested it successfully to populate data in a
DataGrid. When I added multiple modules and menu, I modified DataManage and
might have missed either some sequence or properties.
I am using only one menu which is the starting page. Main Application call this
page(view as this page and Eventmap) then event is dispatched from this module
to get the data for menu. I have added
addEventListener(MenuEvent.ITEM_CLICK,onMenuClick) to call the other
modules(component) attached to menu items. Hope this is appropriate. Now my
concern is every called module(mxml component) as well as menu using the same
webservice and same method with different arguments. Does this need a separate
event handler for each module(component) as it is doing for menu(given below)
and in the SAME eventmap. Do I need to write a separate method in DataManger
for each result handler. One module may have more than one operation (fetch and
save). My worry is it will become huge if I add 150 screens and 100 reports. Is
there any way to make event handler generic and same with DataManger. Please
suggest. I am new to both OOP and Flex.
<EventHandlers type="{GetDataEvent.GET_M}" debug="true">
<WebServiceInvoker wsdl="http://10d/MyApps/App?WSDL";
method="mtExecute"
arguments="{[SessionManager.dbSessionID, event.dbParam]}"
debug="true">
<resultHandlers>
<!-- parse the results -->
<MethodInvoker generator="{DataManager}" method="saveMenuData"
arguments="{resultObject}" />
<EventAnnouncer generator="{GetDataEvent}"
type="{EventSequenceDispatcher.EVENT_FINISHED}" />
</resultHandlers>
</WebServiceInvoker>
</EventHandlers>
