That is pretty much my experience with JSF too. I
recently built comparison application to try out
Tapestry;
Struts+Tiles;
Struts+SiteMesh;
JSF(MyFaces);
With exactly the same backend (Hibernate under
Spring).
What can I say: JSF is horrible! Tapestry has a
learning curve, but JSF one was horrifying. I bought
Kito Manns book JSF in Action and it is mind blowing
how cumbersome simple things are:
JSF documentation is awkward and incomplete;
Lets take parameters for example, simple thing a
parametrized command link:
<h:commandLink
actionListener="#{companyCRUDForm.show}"
action="crud"
immediate="true"
value="show">
<f:param name="id"
value="#{c.id}"/>
</h:commandLink>
1st we cannot call parameterized function- it is
non-argument navigation function, or action listener
that takes ActionEvent, but we cannot control
navigation from the listener, therefore we have
awkward combination of actionListener parameter that
invokes function where we do stuff, and action
parameter that allows navigation.
2nd accessing parameters mind blowing IMO:
from Kitos book examples:
public void doIt(ActionEvent actionEvent) {
String param = null;
List children =
actionEvent.getComponent().getChildren();
for (int i = 0; i < children.size(); i++) {
if (children.get(i) instanceof UIParameter) {
UIParameter currentParam = (UIParameter)
children.get(i);
if (currentParam.getName().equals("param") &&
currentParam.getValue() != null) {
param = currentParam.getValue().toString();
break;
}
}
}
FacesContext context =
FacesContext.getCurrentInstance();
String id =
actionEvent.getComponent().getClientId(context);
System.out.println("In doIt(), component id:
"+id+", param: "+param);
}
What the heck!? Is this friendly and convenient API?
JSF Configuration file, just look at that:
<managed-bean>
<managed-bean-name>globalOptions</managed-bean-name>
<managed-bean-class>com.sourcelabs.demo.webapp.web.jsf.GlobalOptions</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
<managed-property>
<property-name>pageLayout</property-name>
<value>classic</value>
</managed-property>
</managed-bean>
Hey guys, have you ever heard about object
orientation? It looks ridiculous, same way as object
like
Class Person{
String personFirstName;
String personLastName;
String personAge;
}
Cmon JSF guys, get back to school -school year is
about to begin!
PS: Hope I will have time this week and add
documentation to my comparison and publish it.
