get an argument value from grand parent ux in grand child ux

[frankbicknell]

Is that possible? Any tips?

usually window objects transcend generations, if you can get hold of the argument, then i think pass it on to a window object and access it in the child and/or grand child.
just a thought.

Thanks for jogging my memory gandhi, I think I can make it work.

From a child UX, get a pointer to it's parent. Once you have that pointer, you get use it to get a pointer to it's parent... and so on. You can use these...

{dialog.Object}.getTopParentObject();
{dialog.Object}.getParentObject();

Re: get an argument value from grand parent ux in grand child ux

Thanks David, I have been away from the computer for a while and I get rusty real quick these days. After I started experimenting it started coming back to me.
What I needed to accomplish is set a default value of a field in a grandchild ux with the value from a grandparent ux field. I have done this many times. I just had a senior moment I guess.
anyhow this is what I did on the onRenderComplete event of the grandchild ux.

var po = {dialog.Object}.getParentObject();
var gpo = po.getParentObject();
var nCID = gpo.getValue('CID');
var cFileAs = gpo.getValue('FILEAS');

{dialog.Object}.setValue('CID',nCID);
{dialog.Object}.setValue('FILEAS',cFileAs);

Re: get an argument value from grand parent ux in grand child ux

I would like to go back to my original question. Can I access an argument in a grandparent ux from a grandchild ux? The grand parent ux exists so the arguments that were set in that ux exist somewhere.

I am using arguments to pass values from parent to child, which is very robust and works well. I would like to continue using arguments throughout my application if possible.

Another issue I tried is as was discussed in this thread;
http://www.alphasoftware.com/alphafo...iables-in-a-UX

I have the pointer to the grandparent ux but I can't find the variable. I get an error indication that it does not exist. Are those items protected in the ux in which they are created?

gpo.argumentValue('argument_name'); // nice for UX's, but don't know easy way for Grid's

Thanks Rich. I thought I had tried that.

Re: get an argument value from grand parent ux in grand child ux

Is this an argument, set in the Child, and passed in via the argument bindings of an embedded UX? If so, I believe the argument lives in the child, not in the parent. It's established in the child and referenced... set... by the parent. Try {dialog.object}.argumentValue('argName'); in the child ux.

Do you want this argument client-side or server-side? If server-side have a look at e.arguments as well.

Further, how is the argument set? If the argument references a control on the parent, you can use a setting to the parent object with a .getValue() method client-side.

Re: get an argument value from grand parent ux in grand child ux

What I am mainly concerned about is making sure that when I have many tabs with the same ux open, for example the customer edit with different customers in each tab, so that when I open related uxes (child and grand child) I get the correct id's.

One reason I am doing this is so that I can dynamically filter lookups in the grand child uxes. Here is a simple example
customer
-Jobs
-Work orders
--Purchases
-Invoices
-etc

I have a customer ux that has many related child uxes. In the work order child ux I have many related child uxes. In the purchases child to the work order ux, grandchild to the customer ux I need to filter a lookup for the proper job. I want the lookup to contain only the jobs for that particular customer.


I had it working by opening the same uxes with different customers in a new browser tab. Then at some point not sure of what changed the id's started getting messed up. The child and grandchild ids were set to the last opened parent id no matter which browser tab was selected. I was using session variables which was a mistake.

This all was working well for grids. But as I was switching over to uxes I was having trouble getting the ids in the same manner. I couldn't seem to find the right event. Mostly due to my lack of understanding all of the features of the ux.

Now I am starting to better understand the uxes I can see that there are several ways to get the grandparents id. I would like to know the best method to be sure that I get the correct grandparent id's in the related grandchild ux when there are many grandparent uxes open in different tabs. Is it by accessing arguments set in the child or by getting a pointer to the grandparent and getting the value from a control?

Re: get an argument value from grand parent ux in grand child ux

Frank,
I don't know what the "best" way is for doing this type of thing, but what I do is pass arguments through all the levels of my components even if intermediate components do not need them.

Re: get an argument value from grand parent ux in grand child ux

That is interesting Rich. Do you just pass them to an unbound control?

Re: get an argument value from grand parent ux in grand child ux

again i would like to bring up the point i did in post #2, if you assign window objects, say window["something"] = "abc" and window["something2"] = "fgh" they are all available in all the components and the singularity is maintained thru out.
as long as you have access to the one want to save then window objects are very good till the window is closed. if you need to keep them longer then session variables will be good till the session expires, if you need it longer than session then local storage will be good. with all of these you can skip a generation.

Re: get an argument value from grand parent ux in grand child ux

Thank you gandhi. Maybe I am missing something but if I use window variables how will I keep them private? If I open the customer edit ux in a tab pane and set a window variable say window['cusID'] with the value of the records id field. Then I open another customer edit ux in another tab pane and set window['cusID'] to the id of that records id field isn't window['cusID'] going to equal the value from the last opened customer edit ux? Isn't the scope of the window variable the browser window?

Re: get an argument value from grand parent ux in grand child ux

you are correct, i think. opening same component twice was not possible in version 11, may be true in version 12. in that case you are correct. window objects of same lineage will overwrite the last ones. you may have to add additional data to make them private. that i do not know how.
