<fd:on-action>
<fd:javascript>
var widget = event.source;
var row = widget.parent;
var repeater = row.parent;
// Add the first row

// Get number of extra rows to add

This is for adding rows at the end of the repeater - if you want to insert them at a certain position it would be something like...
<fd:action id="insert_items" command="insert_items">
<fd:on-action>
<fd:javascript>
var widget = event.source;
var row = widget.parent;
var repeater = row.parent;
// Insert the first row
repeater.addRow(repeater.indexOf(row) + 1);
// Get number of extra rows to insert
var num_rows_wid = row.lookupWidget("num_rows");
var num_rows = num_rows_wid.getValue();
// Insert the extra rows
for (var i=0;i < num_rows;i++) {
repeater.addRow(repeater.indexOf(row) + 1);
}
</fd:javascript>
</fd:on-action>
</fd:action>

<x-tad-bigger>Instead of using a fd:row-action why not use a fd:action such as:</x-tad-bigger>
<x-tad-bigger><fd:action id="delete_item" command="delete_item"></x-tad-bigger>
<x-tad-bigger> <fd:on-action></x-tad-bigger>
<x-tad-bigger> <fd:javascript></x-tad-bigger>
<x-tad-bigger> var widget = event.source;</x-tad-bigger>
<x-tad-bigger> var row = widget.parent;</x-tad-bigger>
<x-tad-bigger> var repeater = row.parent;</x-tad-bigger>
<x-tad-bigger> repeater.removeRow(repeater.indexOf(row));</x-tad-bigger>
<x-tad-bigger> // Your extra code here...</x-tad-bigger>
<x-tad-bigger> </fd:javascript></x-tad-bigger>
<x-tad-bigger> </fd:on-action></x-tad-bigger>
<x-tad-bigger></fd:action></x-tad-bigger>
<x-tad-bigger>Hope this helps...</x-tad-bigger>
