8:20 a.m.
I am having trouble using the Tomahawk schedule (see
http://myfaces.apache.org/tomahawk/schedule.html ) component in a simple Seam application.
The component renders the day view regardless of the mode or the addition of any entries
to the ScheduleModel. Based on the lack of debugging output, it does not appear to get a
reference to my ScheduleModel implementation. (I am subclassing SimpleScheduleModule
provided by the Tomahawk library such that its getter and setter methods produce log
messages, but again, I get no output.) Others have reported varying degrees of success
(see
http://mail-archives.apache.org/mod_mbox/myfaces-users/200607.mbox/%3C44B...
) with this component when used with Seam, but I basically get nothing, not even any
exceptions.
I have attempted to use both the 1.1.4 and 1.1.5 Tomahawk snapshot releases. I am using
Facelets with Seam and JBoss AS 1.0.1.GA. (Other Seam applications work flawlessly, by
the way.) Other Tomahawk components are working just fine after following the
instructions found at http://wiki.apache.org/myfaces/Use_Facelets_with_Tomahawk . I have
added the following tag to my Facelets tag library definition.

Sample implementation of ScheduleModel.

My simple "controller" class.
package com.mycompany.scheduler;
|
| import java.text.DateFormat;
| import java.text.SimpleDateFormat;
|
| import org.apache.myfaces.custom.schedule.model.ScheduleModel;
|
| public class TriggerScheduleController
| {
| private ScheduleModel model;
|
| public ScheduleModel getModel()
| {
| System.err.println("Giving model " + model);
| return model;
| }
|
| public void setModel(final ScheduleModel model)
| {
| System.err.println("Got model " + model);
| this.model = model;
| }
| }
Note that I started with TriggerScheduleController as a stateful session bean. The class
had the following annotations.
@Stateful
| @Name("triggerSchedule")
| @Scope(SESSION)
And these methods.
@Create
| public void create()
| {
| setModel(new DummyScheduleModel());
| getModel().setMode(ScheduleModel.MONTH);
| }
|
| @Destroy
| @Remove
| public void destroy()
| {
| }
The view, browse.xhtml, contains the following (note it fills in a template).

When exploded, my deployment in JBoss appears as follows.

And for reference, application.xml contains this.

Of course, when I was using a stateful bean, I was passing that through the value
attribute of t:schedule. In that case, I have be supplying the @Out annotation on the
model field. I have even tried making the bean extend SimpleScheduleModel itself and pass
it directly. The configuration you see here is to mimick the known-working example
provided by the MyFaces project (their examples work when deployed in JBoss).
If I upgrade the MyFaces library in JBoss's Tomcat deployment (tried both 1.1.4 and
1.1.5 snapshots), things become even more broken. And again, as mentioned, no messages
with the exception of the println statement in the constructor are produced at runtime.
So, does anyone have any idea what I am doing wrong?
