I have table with 2 generated columns and Bean Item container as its container. I added header click event to the table based on which I perform some action like selecting all records or repopulating the data in to the table. Coming to the issue, When ever I keep on clicking on header, say 5-10 times with in a short span of time, its giving a communication error and some UIDL values in the notification area.
To disable this, So what I am planning to do is there a way where we can disable header click event once the header click event is triggered.
Whats happening is that when ever I click on sort it takes some amount of time(10-20sec) to fetch and populate the data in to the Container. For one request - one sort. So when ever I do a multiple clicks on the column header it throws me a communication error with Some UIDL data - related to the data populated in to the table. Is there a way where I can restrict the user on doing an header click after he clicks once?
Can you anyone pls help or give me some pointers?
