Re: [flexcoders] Code Highlighting Bug?
Brendan,
I am getting the same problem with:
mx:DateField id=dtNeeded disabledRanges={[{rangeEnd: new Date()}]}
selectedDate={detailObject.dtNeeded}
editable=true /
Really Annoying! Adobe, is this a bug and is there a workaround???

[flexcoders] DataGrid Tooltips
With Flex 2, when the user mouses over a row in a datagrid, I would
like to show details of that particular row's object in the tooltip.
The datagrid dataProvider is an ArrayCollection of objects with many
properties. Only a few of the properties are shown in the DataGrid.
I am currently using this to get a custom tool tip...
(mx:script section)
private function createCustomTip(title:String, body:String,
event:ToolTipEvent):void {
var rtt:RequestToolTip = new RequestToolTip();
rtt.title = title
rtt.bodyText = body;
event.toolTip = rtt;
}
mx:DataGrid id=dgRequestList dataProvider={requests} toolTip=
toolTipCreate=createCustomTip('DELETE','Click this button to delete
the report.', event)
mx:columns
mx:DataGridColumn headerText=Id dataField=iRequestId
width=50 / mx:DataGridColumn
headerText=Title
dataField=sRequestTitle width=300/
/mx:columns
/mx:DataGrid
For example, these objects also have sRequestDescription properties
that I would like to show in the tooltip.
Thanks in advance,

OK. I think I have that working.

Steve,
why not use an ArrayCollection? in your result function do something like
this
function result(data:Object):void{
var myModel : ModelLocator : ModelLocator.getInstance();
myModel.myArrayCollection = new ArrayCollection(data.result);
}
You should be able to add Items to your ArrayCollection and see your
datagrid updated.

Using Cairngorm 2
I have a datagrid in my view that is bound to an array in my model
object. My app adds a new item to the array, but the datagrid is not
updated. I see that this may not be possible using arrays and that
arraycollections are recommended. What is the best way to bind
(something) to this array and get the datagrid to update? Any advice?
FYI... The property is an array because it is linked to a ColdFusion
component array property. I tried using Array Collection on my model
object, but it would not convert.

Re: [flexcoders] Re: Cairngorm Newbie Question - Please set me straight
Hank, Thanks for your reply. I am not sure I am explaining this correctly but let me try adding these details and see if this helps. My backend is ColdFusion and I have created Flex remote objects to several CFCs that each correspond to a separate business object (not necessarily one table). For example, I have an employeeGateway.cfc who's methods all pertain to employees (e.g. readEmployeeById(), readEmployeeByUsername(), addEmployeePermission()). From what I understand I have to set up a remote object connection to each CFC that I want to talk to. Although I could create a single CFC to group together lookup table queries I prefer to keep them in their distinct CFCs to allow for future methods related to those objects. Does this clear things up at all or am I still way off? Thanks again for your help!

Re: [flexcoders] Re: Cairngorm Newbie Question - Please set me straight
I do have a service for each CFC.
I have a BusinessDelegate for each as well with a method for each method on
the CFC.
Ex:
public class EmployeeDelegate
{
public function EmployeeDelegate( responder : Responder )
{
this.service = ServiceLocator.getInstance
().getRemoteObject(employeeService);
this.responder = responder;
}
public function readEmployeeByUsername(sUsername:String) : void
{
var call : Object = service.readEmployeeByUsername(sUsername);
call.resultHandler = responder.onResult;
call.faultHandler = responder.onFault;
}
private var responder : Responder;
private var service : Object;
}

OK Thanks for your help. Steve On 12/6/06, hank williams [EMAIL PROTECTED] wrote: Steve, I dont know much about cold fusion, but as a general architectural strategy I think you are mistaken in thinking that combining CFCs to group together lookups. Programming is all about creating simple functions, then creating more complex functions that use the simpler functions and then more complex functions that use those, etc. I dont know what the information you are trying to display is, but I would generally recommend (without knowing the actual specifics here) that you should, as I initially suggested, do this grouping on the server side. This is the kind of work that servers are suposed to do. There is no reason the simpler functions cant also be accessible to the client or to other objects on the server, but if you have a complicated function that builds on a variety of queries that is almost always done on the server side. Of course as I said, I dont know anything about cold fusion, so the mechanics of exactly how you do what I am talking about in CF is beyond me. But If you are doing a ton of massaging of data in the client, it is a sign that you server side code is not delivering high level enough information.
