Hi Christofer,
have a look in the dynamicrepeater.xml example.
Maybe something like the following:
<fd:output id="totalPriceProducts">
<fd:label>Gesamtpreis aller Produkte:</fd:label>
<fd:datatype base="string"/>
</fd:output>
<fd:repeater-action id="addpage" command="add-row" repeater="pages">
<fd:label>Seite hinzuf�gen</fd:label>
<fd:on-action>
<fd:javascript>
// Increment the row creation ID counter (it has been
initialized in
// the flowscript when the form was created).
// This shows how attributes can be used as a communication
means between
// application logic and widget event handlers.
var form = event.source.form;
var count = new
java.lang.Integer(form.getAttribute("counter").intValue() + 1);
var totalPriceCart = form.getChild("totalPriceProducts");
var repeater = form.getChild("pages");
var priceProduct=repeater.getRow(repeater.getSize() -
1).getChild("numberCount").getValue(count);
totalPriceCart=totalPriceCart+priceProduct;
form.setChild("totalPriceProducts");
</fd:javascript>
</fd:on-action>
</fd:repeater-action>
You would need to change pages to your repeater ID. I hope you got the
idea.
