I would use an array of objects to hold different entries. Send the
array to backend for processing in one shot...
public class BasicInformation
{
public var eventDate:String;
//similarly other fields.
public function BasicInformation(eventDate:String //, similarly
other fields)
{
this.eventDate = eventDate;
}
}
So whenever someone adds another row, you push the data in model to an
array:
private var basicInformation:Array = new Array();
function addBasicInformation()
{
basicInformation.push( new BasicInformation(
basicInformationModel.eventDate,
basicInformationModel.facilityDate,
basicInformationModel.sacActual,
basicInformationModel.sacPotential
);
}
You can also create custom component to hold the form-fields:
<mx:HBox height="100%" width="100%">
<mx:TextInput id="txtRCAParticipants1" width="150" text="" />
<mx:TextInput id="txtTitle1" width="150" text="" />
<mx:ComboBox id="cmbTeamRole1" width="100">
<mx:dataProvider>
<mx:Array>
<mx:String></mx:String>
<mx:String>Leader</mx:String>
<mx:String>Member</mx:String>
<mx:String>Advisor</mx:String>
</mx:Array>
</mx:dataProvider>
</mx:ComboBox>
<mx:TextInput id="txtPhoneNumber1" width="150" text="" />
<mx:Spacer width="20" />
<mx:Button label="Delete" click="" />
</mx:HBox>
Then you can reuse it, right now you have hardcoded first set.
There could be better approach, above is just quick idea...

Subject: [flexcoders] Multiple values in a data model
I have an application I am working on where the user can input
information into various text input fields layed out in a HBOX. If
the user needs to add another person for the input they click on an
add event that dynamically creates another row.
My question is what is the best way to tie multiple entries to the
data model? If there is only a one line entry it would be no problem,
but what do you do when you want a data model to hold mulitple
entries from dynamically created input fields to be re-used
throughout the app or sent back to the database?
Any suggestions would be appreciated.
Thanks,
