I am currently creating a page that is accessed via the custom url functionality. Whenever my page does a post-back to the server I lose the window.dialogArguments property therefore losing the ability to access getFields(), container.deleteField() etc.
Is there any way around this?
My first thought was to do all communication with the server via XMLHttpRequest calls, that would get rid of the post-back issue but the problem is the code (from Tridion 5.3) relies heavily on server side logic and its going to be a big job to change it. (5.3 seems to use window.returnValue rather than dialogArguments.
My second thought was maybe I could use some value in window.opener, but I am unable to find the property/function that I need.
You could do the post-back in a separate iframe. That will keep the main window alive and thus keep the window.dialogArguments accessible to your code.
From what I know the window.opener should survive any post-back. So I'm not sure what you are looking for there.
