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
