The problem is, when I right click on the node and select "Rename" the node turns into a text box only for a split second, then it goes back to normal mode.

It seems when I click the rename option, the client side code is firing and the node is turning into a text box. but then somehow a page postback is occurring which is removing the textbox. 

How can I get rid of the issue?
