Java Development Tools

Hi,

I am using jdev 11.1.1.6 version

I am opening a popup on click of a link where programmatically in the first line of the method i am executing #{bindings.createinsert.execute}

now in the popup if the user clicks on cancel popup closes.. now again user clicks on the link popup opens.. like this if he does 3 times.. this createinsert is getting executed 3 times and 3 null rows are getting commited to db on click of save.

On click of the link i want to clear these empty rows in the vo and then perform this create insert.

I have tried

        viewObject.reset();

        viewObject.clearCache();

viewObject.cancelQuery();

viewObject.executeemptyrowset();

viewObject.executequery();

but nothing from the above seem to work.. can someone tell me how to exactly reset or clear these empty rows before performing createinsert.

Thanks,

Vinay
