How do I to access data from objects created with addElement ?
So I have a very simple cutome component with two textInputs
I create these as needed dynamically using
siFormItem = new FormItem(); // Add formItem
siFormAttrbt = new lpSiComp(); // Custom Component
siFormItem.addElement(siFormAttrbt); // Add Custom component to formItem
siForm.addElement(siFormItem); // Add FormItem To form
Greate this works but now how do I get to the textinput data within the
CustomComponents
I get as far as
for (var i:int = 0; i < siForm.numElements; i++)
{
var stringName:String = siForm.getElementAt(i) + "";
var currentElement:IVisualElement = siForm.getElementAt(i);
trace(currentElement);
if (currentElement as FormItem)
{
trace ('Is a formItem');
}
}

Assign it an ID and reference it through that?

This is an excelent approach. Especially given that I have to reference the
same structure for different events.

Just to spit ball an idea. Maybe build up an Array/Vector with the refs to
the items you built out? If you want to reference them by name directly
than maybe build out an object with properties that match the generated ids.
Example of array with items that you built
var arrItems:Array = [];
var siFormAttrbt:lpSiComp // Custom Component
for (var i:int = 0; i < numElementsToCreate; i++){
//form item creation code
siFormAttrbt = new lpSiComp();
arrItems.push(siFormAttrbt);
//code to add siFormAttrbt to form item
}
reference by:
var referenceIndex:int = 5 //to grab the 5th item in the form
var refAttr:lpSiComp = arrItems[referenceIndex] as lpSiComp;
var textInputData:String = refAttr.txtInput.text;
Here's the example with using IDs and an object
var objItems:Object = {};
var siFormAttrbt:lpSiComp // Custom Component
for (var i:int = 0; i < numElementsToCreate; i++){
//form item creation code
siFormAttrbt = new lpSiComp();
siFormAttrbt.id = "formItem" + i;
objItems[siFormAttrbt.id] = siFormAttrbt.id;
//code to add siFormAttrbt to form item
}
reference by:
var referenceIndex:int = 5 //to grab the 5th item in the form
var refAttr:lpSiComp = objItems["formItem" + referenceIndex] as lpSiComp;
var textInputData:String = refAttr.txtInput.text;
I think the array option may be more straight forward when you look back at
the code later on. Hope that helps,
Chris
