C. Fed commented on RF-6839:
----------------------------
I needed to have the lists maintain their order on add/remove, so I ended up
modifying ListShuttle.js in richfaces-ui-3.2.2.SR1jar. This will make every
listShuttle sort this way, which is fine in my case. Ideally a
maintainOrder="true" (or split into maintainSourceOrder and
maintainTargetOrder) would be a nice attribute on listShuttle, but I didn't
have time to put together an example.
Using the regex in there worked since each row had the initial order index as
part of the ID, which I was able to strip out. I'm not sure if that's a good
way to get the index though, since that could change in a future release.
I added the following code to the bottom of the moveItem function:
var regex = /^\w*(\d+):.*$/;
for (var x = 0; x < targetComponent.shuttleTbody.rows.length -
1; x++) {
for (var y = x + 1; y <
targetComponent.shuttleTbody.rows.length; y++) {
var itemX =
targetComponent.getSelectItemByNode(targetComponent.shuttleTbody.rows[x]);
var itemY =
targetComponent.getSelectItemByNode(targetComponent.shuttleTbody.rows[y]);
var orderNumX =
itemX.input.value.replace(regex, '$1');
var orderNumY =
itemY.input.value.replace(regex, '$1');
if (orderNumX > orderNumY) {
var parentItemNode =
itemY._node.parentNode;
var tmpNode = itemX._node.nextSibling;
if (itemY._node != tmpNode) {
// Nodes are more than a
position apart. Move each to the other's position
parentItemNode.insertBefore(itemX._node, itemY._node);
parentItemNode.insertBefore(itemY._node, tmpNode);
} else {
// nodes are next to each
other. just move 2nd in front of 1st
parentItemNode.insertBefore(itemY._node, itemX._node);
}
}
}
}
