As a quick workaround for whatever the problem is, you could certainly
unpack the tomahawk jarfile, find the right javascript files, and add
them directly to your project. Then you would need to manually add the
right <script src=...> tags into any page that uses t:inputCalendar. See
the end of the email for the list of javascript files needed by the
inputCalendar in "popup" mode.
However t:inputCalendar definitely works; the app I work on every day
uses it. There is a small probability that this is something due to the
servlet engine (I use tomcat, not websphere) or the JSF impl (I use
mojarra, not myfaces). But I'm pretty sure we would have had many more
problem reports if this was a common issue.
Are you using Trinidad? I remember seeing some emails in this list about
problems with ExtensionsFilter and trinidad (the filters need to be
declared in web.xml in just the right order for them to work).
You say, however, that the html page doesn't have any <script> tag at
all that is referencing an inputCalendar script. That is odd. You
mentioned before that you have been experimenting with changing the
myfaces resources-handling code. Are you sure you didn't leave any of
your changes in by accident?
Class org.apache.myfaces.custom.calendar.HtmlCalendarRenderer has this:
if(inputCalendar.isAddResources())
addScriptAndCSSResources(facesContext, inputCalendar);
The inputCalendar.isAddResources method looks ok. You will find just an
abstract method with annotation on AbstractHtmlInputCalendar; the actual
component class HtmlInputCalendar is auto-generated. The generated code
(found in target/myfaces-builder-plugin dir after doing build) has:
public boolean isAddResources()
{
if (_addResourcesSet)
{
return _addResources;
}
ValueBinding vb = getValueBinding("addResources");
if (vb != null)
{
return ((Boolean)
vb.getValue(getFacesContext())).booleanValue();
}
return true;
}
In other words, it *does* return true by default, so this looks ok.
The addScriptAndCSSResources method does:
if(javascriptLocation==null)
{
addresource.addJavaScriptAtPosition(facesContext,
AddResource.HEADER_BEGIN, PrototypeResourceLoader.class, "prototype.js");
addresource.addJavaScriptAtPosition(facesContext,
AddResource.HEADER_BEGIN, HtmlCalendarRenderer.class, "date.js");
addresource.addJavaScriptAtPosition(facesContext,
AddResource.HEADER_BEGIN, HtmlCalendarRenderer.class, "popcalendar.js");
}
so you really should be seeing <script> tags for the three files
"prototype.js", "date.js", "popcalendar.js" in your generated html file.
I can't for the moment think why you would not be seeing these. Is there
something unusual about your setup that you haven't mentioned yet? Eg
are you using ajax or frames or SiteMesh or something?

Simon
