I have a scenario, where from a Page link have to render a popup window and on submit of the popup window have to set the drop down selected value of the parent window with the selected values from popup window.
I have created the popup using BookMarkablePageLink and passing page parameters. Have passed the text fileds markupId as parameter and on submit of popup window have used
window.parent.document.getElementById (" + this.parms.get("targetId") + ").value = 'test';
One of the crux in this case is my parent window is in side a tabbed panel, I doubt this might be forcing it to fail to set up.
