Ok, thanks for making this point clear.

Yes, that was one solution we already came up with, but i thought there
would be a better way to do this stuff.
Just for the archives, here is my solution:
---snip---
<fd:action id="myid" repeater="myrepeater" select="select">
<fd:label>Remove selected</fd:label>
<fd:on-action>
<fd:javascript>
var form = event.source.form;
var repeater = form.lookupWidget("myrepeater");
var row;
var message;
for (var i=repeater.size-1; i >= 0; i--) {
row = repeater.getRow(i);
if (row.lookupWidget("select").getValue().equals(true))
{
if (CERTAIN_CONDITION) {
// print ("Not deleting!");
message = i18n("MyCatalogue","You
cannot delete sth that is still
referenced.");
form.lookupWidget("message").setValue(message);
} else {
// print ("Deleting!");
repeater.removeRow(i);
}
}
}
</fd:javascript>
</fd:on-action>
</fd:action>
---snap---
Thanks for your help!
