Hello,

Activating an Ajax listener on the datatable of the data.xhtml results in null result when event.GetObject() is invoked.

Code: Select all

<h1>DataTable</h1>
<p:dataTable var="car" value="#{dtSelectionView.cars7}" selectionMode="single" reflow="true"
		selection="#{dtSelectionView.selectedCar}" rowKey="#{car.id}" paginator="true" rows="10">
	<f:facet name="header">
		List of Cars
	</f:facet>

	<f:ajax event="rowSelect" listener="#{dtSelectionView.onRowSelect}" />

Code: Select all

public void onRowSelect(SelectEvent event) {
	Car car = (Car) event.getObject(); // car is null
        FacesMessage msg = new FacesMessage("Car Selected", car.getId()); // NPE on car.getId()
        FacesContext.getCurrentInstance().addMessage(null, msg);
}
To get the object into the event object PrimeFaces uses the clientId + "_instantSelectedRowKey request parameter.

Code: Select all

            if(eventName.equals("rowSelect")||eventName.equals("rowSelectRadio")||eventName.equals("contextMenu")
                    ||eventName.equals("rowSelectCheckbox")||eventName.equals("rowDblselect")) {
                String rowKey = params.get(clientId + "_instantSelectedRowKey");
                wrapperEvent = new SelectEvent(this, behaviorEvent.getBehavior(), this.getRowData(rowKey)); 
            }
But with Harmony this parameter is never send with the Ajax call

Form Data of the Ajax call with Harmony

Code: Select all

form: form
form:j_idt54_reflowDD: 0_0
form:j_idt54_selection: 3d90cc30

Please use <p:ajax instead of <f:ajax.

Many thanks !!

How simple can a solution be? :lol:

And why didn't I noticed it :oops:

Changed to <p:ajax and it works like charm.
