Subject: [flexcoders] Problem refreshing a datagrid after adding items to
Database
Hi everyone,
I've been playing around with this code for a few hours now and I just
can't figure out how to get the datagrid to refresh after I have sent
a new item to the database.
I've seen many posts about using an arraycollection as a dataprovider
for the datagrid, which is what I'm doing.
Essentially, the httpsrv service gets the data from the server, and
then the addtoarray function populates the arraycollection.
when the data entered in the very basic form gets sent back, the
function also calls the httpsrv again to re-populate the
arraycollection. This is where things don't seem to work as they
should. Perhaps my logic is wrong ;-) but I know that the httpsrv
runs everytime because I added a quick alert pop-up to tell me it's
running.
any pointers will be appreciated!
