I figured this out ... put a 1/4 second sleep in each of the get data cfcs - works like a charm. Using this code before I retrieve a query in my CFC: <cfscript>       thread = CreateObject("java", "java.lang.Thread");       thread.sleep(250); </cfscript> ...that way the CFC retrieving data waits for the updating CFC to finish. > I am using flash remoting to update data and refresh a grid in a flash > cfform.  My goal is to have the user update data in the form (creating > a call to a CFC that that performs a SQL update), then to update the > data in a grid. > > Problem is that when I try to make the two events (update, display) > happen in sequence, they seem to happen at the same time such that the > data in the grid usually does not reflect the change the user just > made to the database.  If I make the grid data load function > independent of the update function (forcing the user to click a > button), the grid refreshes fine. > > I'm sure I am missing something simple ... any help? > > Simplified examples: > > I have tried multiple function calls tied to the button: > onclick="updatethedata('test1','test2'); refreshthegrid();" > > and I have tried putting that stuff in the scripts in my cfform as > well: > > function updatethedata(param1:String, param2:String){      > var responseHandler = {};      > var testresult:String;      > responseHandler.onResult = function( results: Object ):Void {          > //when results are back, populate the grid -- the function is being > called, but it pulls data before the database is updated with data          > refreshthegrid();      > }      > responseHandler.onStatus  = function( stat: Object ):Void {          > //if there is any error, show an alert          > alert("Error while calling cfc:" + stat.description);      > } >      > // do the update      > myService = connection.getService("flashRemotingResponder", > responseHandler );      > <cfoutput>      > var connection:mx.remoting.Connection = mx.remoting.NetServices. > createGatewayConnection("http://#cgi. > HTTP_HOST#/flashservices/gateway/");      > var myService:mx.remoting.NetServiceProxy;      > myService = connection.getService("flashRemotingResponder", > responseHandler);    > myService.updateRegistrant(param1,param2);    > </cfoutput> > }
