Hi,
After a longtime just lurking i have ran into a mindboggling
situation again.
This is the setup:
- regular cairngorm setup
- a view with two inputs, an input and a slider
- the slider has an snapInterval of 5000
- the text input has no Interval, obvious..
- when the user updates the slider he changes the input of the
textfield
- by pressing a button the user triggers the calculation
- the text-input is bound to the value of the model
- triggering the calculation broadcasts a cairngorm event that
updates the model.
This is a simplified situation to figure out what is happening, in
the normal situation both input changes trigger the calculation.
What I want to happen is:
- user can use the slider to approximate the amount
- user can use the textinput to input an specific amount, this sets
the slider in the (snapintervalled rounded) area, but does not
broadcast the cairngorm event (no change event should occur).
How i tried to implement this (just my script block)
import nl.robecodirect.rdinternet.model.ModelLocator;
private var delegate:Function;
function sliderChange(event){
valueChanged(event.target.value);
}
// called on init
private function handleInitialize(){
delegate = mx.utils.Delegate.create(this, sliderChange);
sliderBrutoJaarInkomen.addEventListener("change", delegate);
}
public function inputChange(event) {
siderBrutoJaarInkomen.removeEventListener("change",
delegate);
sliderBrutoJaarInkomen.value=event.target.text;
//this calls the EventBroadcaster..
valueChanged(event.target.text);
sliderBrutoJaarInkomen.addEventListener("change", delegate);
}
What happens is, checked in long debugging,:
After the complete cairngorm command and inputChange methods are
finished, a new change event is fired from the slider, which sets
the input box to the snapintervalled value...
Why o why, it drives me crazy.
Any insights, pointers, are welcome.
A reborn flex newbie ;)
