If you run /examples/components/grid_example.lzx?lzr=swf9&debug=true

and click the mouse on the row with "Emily Dickinson", then click again, you get this runtime error in swf9

TypeError: Error #1010: A term is undefined and has no properties.

Now, apply this patch to get you past that error and to print a message to the debugger when the focus changes:

Then, there will be another runtime error when you try to edit the text field. That can be worked around by making this patch

But there is still an error when trying to edit a text field in the row.

If you compare the debugger messages when running the app in swf8 vs swf9, you see this difference; in swf9, an extra
focus event is sent when you lift the mouse button up, that does not happen in swf8

swf9:


who = [object $lzc$class__internalinputtext_$lz$2Fedittext$2Elzx_160_48]

who = [object $lzc$class_grid]

whereas in swf8 you only see this on mouse down, and nothing printed on mouseup:

who = «lz._internalinputtext_$lz$2Fedittext$2Elzx_160_48#31| .field»
