Flex case file nu 261.. “The mysterious case of disapearing type”

This example is taken straight from Flex 4 Cookbook. It demonstrates how you can search inside of data grid.

Works fine, that not the problem.

The problem is , once you select any cell in data grid an return the the textfield.. you are unable to type anything! Tried different flex 4 sdks tried testing in IE, FF, Chrome .. no luck.

I had it happening in a different project, where I am working with much more complex data grid with custom item renderers and editors, so I chose Flex 4 cookbook example to test if it’s happening in a very simple scenario as well. Also that book was written by Flex experts, so I wanted to confirm it’s not me using the Flex  in the wrong way..

 EDIT: It seems it’s not happening on all computers? On my colleague’s machine this works fine it seems.Does anybody have the same problem as me ?

EDIT2: Solution found!This weird behaviour was down to the flash plugin/active X..

it wasn’t working correctly in version 10,1,50,426 .. but when I upgraded to 10,1,53,64  all works as expected! Must have been some glitch in the plugin.

anyway, I’ll leave this post here, in case somebody will have similar problem.
