So further testing showed the parent SWF can access ordinary variables and functions in the cross-domain child's SWF no problem...
The problems I ran into earlier were due to the fact that I was attempting to have the parent SWF read directly from / write to a dynamic text field in the child SWF so I could make visual observations and was not testing regular vars and functions -- this is what I found: - The parent SWF can obtain the child SWF's textfield itself (i.e. _level0.childLoader.textFieldInstance) - The parent SWF can obtain the text field's _name property. - But the parent SWF cannot obtain the text field's text property....it just always returns undefined. Why this is I have no idea, but at least for this test it's a simple workaround to have a function in the child that can return the text field's text. So the takeaway is that cross domain accessing of variables and functions works (as long as System.security.allowDomain() is in the loadee), but accessing textfields needs wrapper functions. ~Ricky http://codingjourney.blogspot.com On Wed, Dec 10, 2008 at 3:12 PM, Ricky Blaha <ricky.bl...@gmail.com> wrote: > *Background:* > SWF #1 is published for Flash 8 / AS2 on domain name #1 and loads in SWF #2 > (same publish settings) from domain #2.
