Cascading dropdown - setValue of child

[Steve Workings]

Here's a puzzle - I have a dropdown of Countries, and a dependent child dropdown of States/Provinces.

So, I need to setValue for both, but can't get the child dropdown to populate.

This, for instance, assigns correctly for Ret_Country, but leaves the Ret_State control blank:

function one() {
    {dialog.object}.setValue('Ret_Country', 'US');
}

function two() {
    {dialog.object}.setValue('Ret_State', 'NY');
}

A5.executeThisThenThat(one,two);

I suppose I could do a bunch more work with event triggers, callbacks and populating the list choices with callbacks and populate accordingly, but it sure would be nice if I could make this or a version of it work. Any ideas?

Ok let me guess it is not working because the state field is not populated yet.
Work around.
Fill another , non bound, field with the value of the state field and in the on change of that field you fill the state field.

Steve, I think it's a timing issue.

If you set a timeout around the second call, it should populate for you.

{dialog.object}.setValue('Ret_Country', 'US');

setTimeout(function(){ {dialog.object}.setValue('Ret_State', 'NY'); }, 500);

Not a timing issue Nate. I've tried putting a button on the UX and delivering a value straight to the control, but it won't do it. It's a "conflict" issue with the cascading dropdown.

And Pieter's suggestion is interesting, but I'm going to have to spend some time seeing if I can make anything out of it. This needs to be able to be changed by the user, but before they get to it, if I have it, I need to fill it with their existing value.

this is on a list control? or just dropdown controls in an ux/dialog?

Re: Cascading dropdown - setValue of child

Just a followup on this. I never found a way to do this with the built-in cascading dropdown in place. So I just revised it, initially populating both dropdowns with e.rtc lists, then using the onChange event and populateDropdownBox() on the Country control to repopulate the State/province dropdown.

Re: Cascading dropdown - setValue of child

since I do not have access to list, I won't know how this is done.
usually the cascading dropdown needs the data feed to be the same for the parent and the dependent child so they can relate to each other. is this true in the list also?

Re: Cascading dropdown - setValue of child

Gandhi - It goes like this:

You just make a callback on the parent dropdown onChange event. That callback queries the correct data to fill the child dropdown -- using the submitted parent value for the filter. Then use the populateDropdownBox() method to repopulate the child. Vides D53, D59 and D60 are all pertinent here.
