******EDIT********** I found out that I just made a mistake. I ended the popupbutton tag with /> instead of >. ******EDIT**********
I know this is not the forum for this question, but I also know that the people that read this forum are superior to all others. After buttering you all up, here is my issue. I have come across a sample that adds controls to a popupbutton, such as a datagrid or tree. In the mxml there is a component popUp, I am getting an error message on the this component. �??could not resolve <mx:popUp> to a component implementation", I am using Flex Builder 3 and sdk 3.5.
