ActionScript WARNING: Text field variable names are not supported in ActionScript 3.0. The variable 'btnName' used for an unnamed text field will not be exported.
ActionScript Warning Description:
So I was going back to restructure a project that I had done in AS2 and a previous version of Flash. I thought I had converted all of the old AS2 code, and components, and naming conventions, etc... when this error popped up. The error made a lot of sense until I went to fix it. The image below is what I saw when I went to the place that I thought be the resolution to this error.
Flex / Flash Text Field Variable Warning Fix:
I searched around at other buttons and tried to find something else that might have been it even though I knew that this was the correct text field. The way to solve this is to revert back to AS2 in your publish settings ( FILE >> PUBLISH SETTINGS >> SCRIPT drop down) and then go back to the text field in question and you will be able to delete the variable name. Don't forge to return to ActionScript 3.0 after you delete the variable name.
and with this option selected you can then delete the variable name as shown below.
This should help you resolve Flex / Flash Text Field Variable Warning
Thanks and as always Happy Flashing
