I have detected an issue when I binding a component into a managed bean from a page fragment which is a View of a TaskFlow exposed to JSF as a Region.
This issue happened when I exposed same TaskFlow as region two or more instances in the same JSF. The component which is binding only rendered in last Region.
Jdeveloper 12c (12.1.2.0) ADF12c.
This is the code:
Page Fragment:
<?xml version='1.0' encoding='UTF-8'?>
<ui:composition xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:af="http://xmlns.oracle.com/adf/faces/rich">
<af:panelGroupLayout id="pgl1">
<af:inputText label="Label 1" id="it1" binding="#{bindingComponentBean.inputText}"/>
<af:button text="button 1" id="b1"/>
</af:panelGroupLayout>
</ui:composition>
Managed Bean(in Request Scope)
package com.edisa.test.errors.view.backing;
import oracle.adf.view.rich.component.rich.input.RichInputText;
public class BindingComponentBean {
private RichInputText inputText;
public BindingComponentBean() {
}
public void setInputText(RichInputText inputText) {
this.inputText = inputText;
}
public RichInputText getInputText() {
return inputText;
}
}
