when dealing with CellWidgets that gets their data through RequestFactory
two of the steps are:
1- one requestFactory call to get the count // this is done once
2- requestFactory calls to get the data for new range,
as RangeChangeEvent fires.
these two steps are necessary to set CellWidget's setRowCount and setRowData
my question is, due to Asynchronous nature of RequestFactory,
it could be the case that Step2 gets executed before step 1 completes,
therefore we wouldnt have the count.
and if I use step1 (requestfactory.count) inside step 2, it would get called
for every range change event,
but this would be unnecessary because we only need to count records once,
not after every range change.
Below you can find a link to code snippet of my CellWidget + RequestFactory
CellList+RequestFactory: http://pastebin.com/wY34jiuJ
could you please tell me how I can improve this code ?
mainly the guaranteed and correct order of RequestFactory calls for getting
"Count of Items"
and "List of Data for current Range"
Thank You
