CB

Could reproduce issue:

1. edit without closing plugin of line e.g. 5 (keeping it checked out)
2. click the enable of a line after that one (e.g. 12)

The Javascript checks presence of all checkboxes, and of course fails because there is a lock image instead of the checkbox.

This is due to the "break" in here:

function cbListItemTask( cb, task, subtaskName, subtaskValue, fldName, id ) {
var f = cbParentForm(cb);
if (cb) {
for (i = 0; true; i++) {
cbx = f.elements[fldName+i];
if (!cbx) {
break;
}
