My DynaForm implementation is giving me all sorts of problems on primefaces 6. It seems like a very basic case that just isn't working

One is a stack overflow, the other is null data values in the controller after the form is submitted.

Code: Select all

	at com.sun.faces.facelets.el.TagValueExpression.getValue(TagValueExpression.java:109)
	at javax.faces.component.ComponentStateHelper.eval(ComponentStateHelper.java:194)
	at org.primefaces.extensions.component.base.AbstractDynamicData.getValue(AbstractDynamicData.java:109)
	at org.primefaces.extensions.component.dynaform.DynaForm.invokeOnChildren(DynaForm.java:251)
	at org.primefaces.extensions.component.base.AbstractDynamicData.invokeOnComponent(AbstractDynamicData.java:455)
Another is that I'm only getting null data values back into my controller after the form is submitted.

My code looks something like this:

Code: Select all

    <link type="text/css" rel="stylesheet" href="#{request.contextPath}/themes/bootstrap/skin.css"/>
<h:panelGrid columns="2" style="margin-top: 10px">
    <p:commandButton value="Add Member" icon="ui-icon-arrowthickstop-1-w" onclick="PF('dlgAdd').show();">
        <p:resetInput target="dlgAdd"/>
    <p:dialog header="Add Member" widgetVar="dlgAdd" resizable="false">
            <h:panelGroup id="dynaFormGroup">
                <p:messages id="messages" showSummary="true"/>
                <pe:dynaForm id="dynaForm" value="#{memberViewController.model}" var="data" columnClasses="label-container, field-container">
                    <pe:dynaFormControl type="input" for="txt">
                        <p:inputText id="txt" value="#{data.value}" required="#{data.required}"/>
<h:form id="form">
and my controller looks something like this:

Code: Select all

	public void init() {
		memberView = MemberView.builder().build();
	        model = new DynaFormModel();
        	DynaFormRow row = model.createRegularRow();
	        DynaFormLabel label11 = row.addLabel("Last");
        	DynaFormControl control12 = row.addControl(new FormProperty("Last", false), "input");
my pom dependency is

Code: Select all

How do you get a stack overflow error then if you're able to submit the form?
