I have a modal popup that appears whenever an editor tries to save a component with some values (a date field in the past in this case).

In this popup I show the editor a few options (very similar to the default "Open Shared Item" dialog) and an OK/Cancel button combo. On Cancel I fire the "cancel" event and the editor goes back to the editing screen, all good here. On "OK" I want to change the value of the field to match whatever the editor selected, then save.

I tried to use an approach with FieldBuilder and the sample Boris mentioned on this other topic but I can't get to the field from my popup dialog.

Any suggestions on how I can go and modify the xml of the item (could be also a page) from a modal popup?

EDIT: Code used in getControlForFieldName

function getControlForFieldName(name) {
    var fieldBuilder = $display.getView().properties.controls.fieldBuilder;
    var fieldsContainer = fieldBuilder.properties.input;
    var fieldsNode = fieldsContainer.getElement();
    var fieldContainer = $dom.getFirstElementChild(fieldsNode);
    while (fieldContainer) {
        var labelNode = $dom.getFirstElementChild(fieldContainer);
        var fieldNode = $dom.getNextElementSibling(labelNode);
        var control = fieldNode.control;
        if (control.getFieldName() == name) {
            return control;
        }
        fieldContainer = $dom.getNextElementSibling(fieldContainer);
    }
}

EDIT #2

After Frank's advice, and some help from Jaime & Frank offline, I got it to work as follows:

  1. The popup is called from a Command Extension (Save & Close in my case)
  2. The command.js specifies an event handler that gets called on "submit" (== OK was pressed)
$evt.addEventHandler(p.dialogPopup, "submit", 
    this.getDelegate(this._onPopupSubmit));

In my popup I am passing the selected item (it's a keyword ID) to the event handler:

this.fireEvent("submit", { id: select.options[select.selectedIndex].value });

and now back in the event handler _onPopupSubmit(e) I just read e.data.id, load this keyword, get properties like ID & Title, and update the metadata of the item using item.setMetadata("new metadata with updated values").

Simple :)

Your code runs in a popup, so any references you make to global variables will be taken from the popup window.

So when you get the fieldBuilder:

var fieldBuilder = $display.getView().properties.controls.fieldBuilder;

$display is a reference to a global variable. So this actually looks for the FieldBuilder in the popup window (which doesn't have one).

To get the FieldBuilder of the Component window, you can get it from the opener:

var fieldBuilder = opener.$display.getView().properties.controls.fieldBuilder;

You might want to consider actually passing the updated value to either a callback function or with a (custom) event though, since that makes your popup less dependent on opener. trick.

  • Thanks Frank, your answer was half of what I needed :) after a short discussion - and based on your insights - I passed the result back to my "submit" event handler, I'll post the correct answer soon, trying to wrap up the code now – Nuno Linhares Jun 26 '12 at 15:45
