MyFaces Discussion
I am planning to write a simple component,
My component will take one parameter from the tag through the Tag class.
I am using my tag in the jsp page like this:
<test:testTag jspID="<%=request.getParameter("id")%>">
My Tag class is like this:
public class TestTag extends UIComponentTag {
private String jspID = null;
public String getRendererType() {
return null;
}
public String getComponentType() {
return "com.tags.BreadCrumbs";
}
public void setJspID(String jspID) {
this.jspID = jspID;
}
public void setProperties(UIComponent component) {
// always call the superClass method first
super.setProperties(component);
setString(component, "jspID", jspID);
}
public void setString(UIComponent component, String attributeName,
String attributeValue) {
if (attributeValue == null)
return;
if (isValueReference(attributeValue)) {
setValueBinding(component, attributeName, attributeValue);
} else {
component.getAttributes().put(attributeName, attributeValue);
}
}
public void setValueBinding(UIComponent component, String attributeName,
String attributeValue) {
FacesContext context = FacesContext.getCurrentInstance();
Application app = context.getApplication();
ValueBinding vb = app.createValueBinding(attributeValue);
component.setValueBinding(attributeName, vb);
}
public void release() {
super.release();
jspID = null;
}
}
My Component class code is like this:
public void encodeBegin(FacesContext context) throws IOException {
ResponseWriter writer = context.getResponseWriter();
String clientId = getClientId(context);
String jspID = null;
jspID = (String) getAttributes().get("jspID");
System.out.println("jspID in Component class:"+jspID);
}
If I call this component by changing id value, setProperties method is
not calling every time.
TIA,
Regards,
Ramesh
