Re: T5 : declaration of pages and components packages from a library

While we're tossing out ideas, I accomplish the same thing withoutsubclasses using layout components, which themselves (seamlessly) handlecommon CSS via @IncludeStyleSheet (or whatever its called). Any page (orcomponent for that matter) that has specific styles (or scripts) canadditionally add them in the same manner. It's these kinds of facilitiesI mean when I say that T5 provides ways of shared state/behavior, whichare (imo) superior to subclassing.

I have a few components and pages that I extend, and I put them in a
directory called "base", at the same level as the pages and components
packages.

For instance I have an AbstractReportPage that references Tapestry
ASOs, Injects things and Persists things.  Then I have a few report
page classes that implement different flavors of very similar things.

It could be done differently for sure--This is just one way that works for me.

I also use the base directory for concrete Tapestry related classes
that don't belong in pages, components, services or mixins.  One
example is a class than has the injected paths to all my css files and
some images that are used across several border classes.
Then I can do

public class Border extends AssetContainer{
}

Have you tried the following ?

Suppose org.man.tapestry5.components will hold the new
components.

1) add the following to AppModule


    public static void
contributeComponentClassResolver(Configuration<LibraryMapping>
configuration)
    {
        // Creates a virtual root pacakge for
pages,components.
        configuration.add(new LibraryMapping("man",
"org.man.tapestry5"));
    }

2) Suppose in  org.man.tapestry5.components, we have
component PageLinkPopup.java.

Usage :

<a href="#" t:type="man/pagelinkPopup" t:page="home"
   windowName="literal:my windown" features="literal:
'resizable,scrollbars,top=100,left=200,height=300,width=500'"

Home</a>

or


<t:man.pagelinkPopup page="test/sum"
   windowName="literal:sum" features="literal:
'resizable,scrollbars,top=100,left=200,height=300,width=500'"

Sum</t:man.pagelinkPopup>

Hi all,

I need to import in my tap5 project a library which
includes tap5 pages
and components.
But when i try to extend a page from the library in
my project, i get
the following exception :

java.lang.RuntimeException: Base class
com.mylibrary.pages.FramePage
(super class of com.myproject.pages.Start) is not in
a controlled
package and is therefore not valid. You should try
moving the class to
package com.myproject.base.

Should i declare the 'pages' and 'components'
directories of my library
in the tapestry.app-package context of my web.xml ?
If yes, what is the
syntax to do such a declaration ?

Thanks in advance.

Stephane
