Communication between Components

[Pizzadude]

I have a parent UX called Loads

In the loads UX I have an embedded pagelayout named Stops, alias Stops.

In the pagelayout there is a UX named Pickup, alias Pickup. It is the only component in the pagelayout.

I want the parent UX to execute methods on controls in the Pickup UX.

I have not been able to figure out how to get a pointer to the Pickup UX.

I have tried var pickup = {dialog.object}.getChildObject('STOPS_PICKUP');

Any help is appreciated.

Re: Communication between Components

That was a really well structured question... thanks.

I believe I've put together the same structure that you have.

This code... the same as yours... seems to work. What methods do you want to use?

debugger;
var cObj = {dialog.Object}.getChildObject('STOPS_PICKUP');
var name = cObj.getValue('FIRSTNAME');

I have a Firstname control on the UX which is a UX Component inside a Page Layout.
My PageLayout is embedded into a Parent UX

I have a button on the Parent UX executing the code above. Name is set.

Re: Communication between Components

You solved my problem!

This is what I had been trying to test:

var pickup = {dialog.object}.getChildObject('STOPS_PICKUP');
var val = {dialog.object}.getValue('ShipperIndex_PK');
alert(val);

This is what works:

var pickup = {dialog.object}.getChildObject('STOPS_PICKUP');
var val = pickup.getValue('ShipperIndex_PK');
alert(val);

I assumed my pointer was that part that didn't work. I should have posted the whole snippet.

This is a new technique to me. Now that I know how to do it correctly. I can use any number of methods.

Hopefully, others can benefit from this example.

Thanks for your help

Re: Communication between Components

Yes... your original code is pointing to the parent object.
It's interesting that alpha puts the page and embedded object aliases together to id the object... very cool I though.
Glad you got it working.

Re: Communication between Components

Another piece of this puzzle....

From the Pickup UX, how to use methods of controls in the Loads UX?

The parent of the Pickup UX is the pageLayout, so the Loads UX is a grandparent.

How do you pass values to a grandparent?

Re: Communication between Components

I'm trying to make this work using getTopParentObject()

So far, this throws and alert of "false"

var parentObj = {dialog.object}.getTopParentObject({dialog.object}.getValue('FreightBillNum'));
alert(parentObj);


And this gives no alert at all

var parentObj = {dialog.object}.getTopParentObject();
var FBnum = parentObj.getValue('FreightBillNum');
alert(FBnum);


Again, all help is appreciated.

Re: Communication between Components

Just curious. Why involve the PageLayout component?

You have only 1 UX in the PageLayout... anything else?

Re: Communication between Components

The pagelayout will have several components. Pickups and deliveries, up to 10. I am just starting to build it and I want to get the communication script working first.

Re: Communication between Components

I think you'd be better off using a UX instead of the PageLayout. Same idea... way more flexibility... far more current.

The PageLayout is not a true component the way the Grid and UX are. You can't get a parent object of a PageLayout.

You'd have to hard code the object reference which is not a good idea. DLG1_DlgObj would get you the parent in this case... but not advisable.

Re: Communication between Components

You may be right. The pagelayout seems like a good tool because of the built-in ability to show/hide tabs.
