Hi All,
I came across one situation when using dashboard component of primefaces.
Running code bellow gives me following error
Caused by: javax.faces.FacesException: Cannot find dashboard "board" in view
What could be possible solution if I need to have scenario like following?

Code: Select all

<p:growl id="growl" showDetail="true" />
<p:dashboard id="board" model="#{dashboardBean.model}" 
<ui:repeat var="species" value="#{dashboardBean.speciesList}">
			<p:panel id="travel" header="Travel" toggleable="true" closable="true" style="width:200px">
		                <h:outputText value="#{species.name}" />
			<p:draggable for="travel" dashboard="board" helper="clone"/>

Sorry for bothering,
adding full path for board as dashboard=":board" helped me out

Sorry for re-opening this thread,
but I have exactly the same problem, and I've tried with the ":board" id for the draggable's dashboard attribute, but still it does not find the component in the tree.
here the code:

Code: Select all

<ui:define name="centerArea">	
				<p:fieldset legend="Available Widgets" styleClass="hidden startClosed avWidget">
					<p:dataGrid id="availableWidgets" var="widget" value="#{dashboardBean.availableWidgets}" columns="1">
							<p:panel id="pnl" header="#{widget.name}" style="text-align:center">
								<h:panelGrid columns="1" style="width:100%">
									<h:outputText value="#{widget.description}" />
							<!--p:draggable for="pnl" revert="true" helper="clone" handle=".ui-panel-titlebar" stack=".ui-panel" opacity="0.3" scope="w" dashboard="board" /-->
							<p:draggable for="pnl"  helper="clone" dashboard=":board" />

			<p:dashboard id="board" model="#{dashboardBean.dashboardModel}" style="min-height: 400px;">
				<p:panel id="sports">
			              Sports Content
				<p:ajax event="reorder" listener="#{dashboardBean.handleReorder}" />
Strangely the component is not found, even if the whole UIView root is traversed!
Could somebody help me?

Thanks and regards,

I've figured out the correct id to use in order for JSF to find my component.
The problem was that the dashboard component with id 'board' was under a htmlform named 'centerAreaForm'.
Going through the JSF componentBase class, the findComponent method (here below):

Code: Select all

private static UIComponent findComponent(UIComponent base,
                                             String id,
                                             boolean checkId) {
        if (checkId && id.equals(base.getId())) {
            return base;
        // Search through our facets and children
        UIComponent result = null;
        for (Iterator i = base.getFacetsAndChildren(); i.hasNext();) {
            UIComponent kid = (UIComponent) i.next();
            if (!(kid instanceof NamingContainer)) {
                if (checkId && id.equals(kid.getId())) {
                    result = kid;
                result = findComponent(kid, id, true);
                if (result != null) {
            } else if (id.equals(kid.getId())) {
                result = kid;
        return (result);

does not search recursively 'NamingContainer' objects. Since the HTMLForm is a NamingContainer, that part of the tree was skipped.
Changing the id to lookup in ':centerAreaForm:board' in my example above fixed the problem, sinche first is the NamingContainer resolved, and the the board.
