I guess you should try changing your Data Model such that your input to the table is only the data that you want to see on the page and other details to be obtained only for the selected rows.

Because once a row is selected, I need the cell value in some columns (poeColumn, distanceColumn, and directionColumn). But those columns have to be hidden in the web page according to client's requirement. For I need the cell values of the hidden columns, I cannot use the rendered="false" attribute. What I tried was <h:dataTable .... columnClasses="codeColumn, descriptionColumn, poeColumn, distanceColumn, directionColumn" ....> and render all columns. In my CSS, I have .poeColumn{ display:none;} .distanceColumn{ display:none;} .directionColumn{ display:none;} although the 'values' in those columns are hidden, I cannot get rid of the 'heading' of those columns (I did not even specify the 'header'). What is wrong? What should I do? ________________________________________________________________________ ____________ Take the Internet to Go: Yahoo!Go puts the Internet in your pocket: mail, news, photos & more. http://mobile.yahoo.com/go?refer=1GNXIC
