SecurityError: Error #2123: Security sandbox violation: BitmapData.draw:

[FlashGodThe2nd]

Hi,

I am developing an swf in Flash Builder 4.7 to run in the FlashPlayer_sa.exe (11.5). Inside this application I load another swf from the same folder and inside this one I load a video from a subfolder.

To have an paging effect for my content I use a bitmap copy from the original content. When I have my videos attatched I can make my bitmap copy (copypixels) from the content clip and the video inside it. Now the 'funny' thing is when I set the stream of the video to null I get this sandboy violation error:

SecurityError: Error #2123: Security sandbox violation: BitmapData.draw: file:///P:/_projekte/....

I also add my project folder to trusted locations in global flah settings. It seems that the securety check has a problem with a stream of the value null and acts like this is from a different domain. Any way to workaround this?

if the draw method is applied to something loaded from another domain, that security issue is expected.  to remedy, use a cross-domain permissions file.

if that loaded object is from the same domain, use a relative (not absolute) path in your urlrequest.

The problem is that the video stream is set to null. So there is no domain and no place to put a permission file.

flash is probably looking for a null file.

what's that full error message.

[FlashGodThe2nd]

Yes I guess flash is looking for a permission file of the null stream, does not find it and marking it as permission error. There wasn't much more error text but some code references.

Now I just set my old stream to stop/pause as a workaround.

Edit:

When I use video steams in flash I keep the video added to the destination movieclip to avoid memory loss that occured  using new network connections. So that is why flash is looking for a permission of an empty video stream.
