RE: Option transfer select (WORKAROUND FOUND)

[Jon Pearson <Jo...@sixnet.com>]

Well, I think something may be wrong with the Struts2 javascript code.
But I was able to make it work anyway by writing this function:

117 function selectAndSubmit() {
118 var list = document.getElementById("update_chosenColumns");
119 for (var i = 0; i < list.options.length; i++) {
120 list.options[i].selected = true;
121 }
122
123 var form = document.getElementById("update");
124 form.submit();
125 }

Which I call in the onclick="" handler for my form submission.
