Hi Akhil, The callLater() method queues an operation to be performed for the next screen refresh, rather than in the current update. Without the callLater() method, you might try to access a property of a component that is not yet available. The callLater() method is most commonly used with the creationComplete event to ensure that a component has finished being created before Flex proceeds with a specified method call on that component.
The example in the below link uses a call to the callLater() method to ensure that new data is added to a DataGrid before Flex tries to put focus on the new row. Without the callLater() method, Flex tries to focus on a cell that does not exist and throws an error: Link: http://livedocs.adobe.com/flex/2/docs/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Parts&file=00001438.html Regards, Kalpesh Mahida On Fri, Mar 27, 2009 at 1:14 AM, Shaleen Jain <[email protected]>wrote: > > Akil, > > What is your exact problem? > How you are currently calling that function which need to be in sync > with your result handler? > > > -Shaleen Jain > http://shaleenjain.blogspot.com > > On Mar 26, 7:28 pm, Akhil Agrawal <[email protected]> wrote: > > i have to cause the that part of code on wait until the query result > > is not returned in resultHandler of remoteobject that is after the > > remoteobject call > > how can i do this. how can i synchronize the resulthandler with > > execution of my code > > query result may take several minutest to return > > plzzz help > > > > thanks > > > > regards > > akhil > > > > On Mar 26, 2:21 pm, kalpesh mahida <[email protected]> wrote: > > > > > Hi, > > > > > I think callLater() function might help to do so here is some > description > > > from the adobe doc. > > > > > public function callLater(method:Function, args:Array = null):void > > > <../../specialTypes.html#void> > > > > > Queues a function to be called later. > > > > > Before each update of the screen, the Flash Player calls the set of > > > functions that are scheduled for the update.
