ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.

Hi All
I am trying to make Video Gallery in AS 3.0. I have placed bunch of containers on my main stage. When user double clicks on any video thumbnail the main videos going to be played on the main stage. XML is loading external videos. The user can also drag the thumbnail and drop(multiple instances of thumbnails) on the main stage to play the main video.
The UILoader component is loading external swfs ( containing external FLVs)on drag and drop on the main stage. Also user would be able to drag and drop the already played videos.
Now my problem is that "When user tries to double clicks on the thumbnial and the video is going to be played on the main stage, when user tries to move that video he will get the run time error 'ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
at flash.display:isplayObjectContainer/getChildIndex()
at MethodInfo-1092()'"
To track which video has been selected i used getChildIndex()method.That only happens when user tried to drag the video played by clicked thumbnail not by the dragged thumbnail.
Sorry for the long mail but I have to explain everything to make things clear.
Anybody knows where I am going wrong and how to fix this problem.
Any help will be highly appreciated.
Regards,
Anuj

I get that message when my method is trying to access an object that isn't there- or think is not there.

How are you supplying the object to the method? How does it know which object to "getCHildIndex()" of?

Hi ultraky
Thanks for reply.
Here's my code for that. I made 'container' of type Sprite and inside the container I have my UILoader component. On Mouse_Down I am allowing myUILoader to start drag and on MOUSE_UP I am allowing it to stop drag and put the container whereever it was left mouse. I am checking if the existed object hits already existed object then it will be replaced.
Please let me know if it is clear and I will appreciate if you will fix this thing for me.
Thanks a lot.
