aka: Licensing the AdvancedDataGrid and Flex Chart components
aka: Getting rid of the Flex Data Visualization Trial watermark
If you want to set up an automated build machine to build your Flex projects, you’ll get the Flex Data Visualization Watermark on your AdvancedDataGrid and Chart components unless you properly license them. And no, you don’t have to install Flex Builder. (And it’s not license.properties! That was the first thing that came up in my Googling, but that was for Flex 2.)
Just find your flex-config.xml file, which will be in your SDK directory under “frameworks”. On my build machine, that is c:\FlexSDKs\3.3.0\frameworks\flex-config.xml
At the bottom you will want to add these lines:
flexbuilder3 1377-rest of your serial number here
I learned it all by reading this helpful post.
