I'm new to flex, actually I'm reading a simple tutorial about Flex 4 (I'm using flash builder 4.5) this is the tutorial.
I added a RichEditableText and then I should specify the property selectionColor, but when I add it to the source code, the IDE give me an error like this property do not exist.
<s:RichEditableText x="179" y="95" text="hello" fontSize="24" fontWeight="bold" color="#E52222" selectionColor="#000000" />
