I am new to MyFaces Trinidad component library and I am trying to do some
pretty simple stuff. I am experiencing a problem with getting the
tr:commandButton to actually invoke the managed bean's method. My setup is as
follows:
- Ubuntu Linux 64-bit
- Sun JDK 1.6.0_20
- Tomcat 6.0.29
- Apache MyFaces JSF Core 1.2.9
- Apache MyFaces Trinidad 1.2.13
- Facelets 1.1.15
- Development IDE = Eclipse Helios
For testing I have made reduced the eventHandler method called by the Search
Button do nothing but System.out.println("..."), to confirm if it is being
called. It is not. Any ideas on what I am missing (something obvious, I am
sure)?
Here is the xhtml file with the unresponsive commandButton:

Here is the managed bean snippet:

String searchString;
String fileName;
...
...
public void loadDrawingResultsEventHandler(ActionEvent event)
{
System.out.println("Drawing Results loaded!");
}
}

<context-param>
<description>
This parameter tells MyFaces if javascript code should be allowed in
the rendered HTML output.
If javascript is allowed, command_link anchors will have javascript code
that submits the corresponding form.
If javascript is not allowed, the state saving info and nested parameters
will be added as url parameters.
Default is 'true'</description>
<param-name>org.apache.myfaces.ALLOW_JAVASCRIPT</param-name>
<param-value>true</param-value>
</context-param>
<context-param>
<description>
If true, rendered HTML code will be formatted, so that it is
'human-readable'
i.e. additional line separators and whitespace will be written, that do not
influence the HTML code.
Default is 'true'</description>
<param-name>org.apache.myfaces.PRETTY_HTML</param-name>

<context-param>
<description>
If true, a javascript function will be rendered that is able to restore the
former vertical scroll on every request. Convenient feature if you have
pages
with long lists and you do not want the browser page to always jump to the
top
if you trigger a link or button action that stays on the same page.
Default is 'false'
