## Hi After Deleting a Library Symbol I get Error 1034 when debugging the FLA. \*“TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::MovieClip@660f5f1 to fl.controls.CheckBox. at flash.display::Sprite/constructChildren()” \*The Library symbol I deleted contained a variety of Components/or Controls , one of which was the checkbox component. So if I now delete the checkbox from the symbol it will continue to the next component. Note : the original checkbox is still in the library.

## Using a backup version I have recreated the error, through simply deleting a symbol. So I think its some form of IDE persistance issue.

Any quick way to reinstiute the components without making the issue worse ?
