Returning a value back from a PopupPanel OR DialogBox

[Veeren Jote]

I have a small helper popup to enable shortlisting few values out of which user will select after doing a small filter.
This value/object needs to be sent back to the parent window.

Has anyone done something similar before?

In our normal HTML/Javascript environment, we would that easily by doing something like

parent.window.formName.elementName.value = newValue;
and the value would be sent from child window to parent window.

Thanks in advance.

Usually I expose a public method in the parent which the popup can call and pass whatever objects that are required. Does this answer your question or did you mean something else?

[Veeren Jote]

yes, but the child window needs to get an handle on the parent window, then it can access the setter/getter and set the value.
Will try this approach and let you know,
Thanks Maneesh.
