Apply template is not getting highligthed

Hi,

I am a fresher to Web DynPro Java. I have an issue. Consider i right click a button in the Layout and when I try to apply template for the button, it is not highlighted. Is there any settings regarding it. We have reinstalled the SAP Netweaver Studio. But there is no change. Please give an appropraite solution for this

Regards,

Praveen
