Re: multiple HTMLs to one Page

  Yeah - I've got the Page and Java files written - the question is what does the application (foo.application) file look like?

Sure. It only requires a little more java code to keep track
of which mode you're in, and then make the HTML template
do the right thing depending on the mode. Here's the bones of
such a page I did. In this case there was nothing pertinent in
the .page file. I didn't try to separate viewing from editing...
adding was the only extra 'mode'.

EmployeeEditor.java:

public boolean getInserting()
{
// Fill in however you determine whether you're in 'add' mode...

// If we're editing a new object -- oid == 0 -- we're inserting.
return (((Integer) data.get("oid")).intValue() == 0);
}


EmployeeEditor.html:





INSERTING



....
inserting -->
 [input] 

 [input] 


You might prefer that the Delete button always appear but be disabled
(grayed out), by adding a binding like: disabled="ognl:inserting" .

Oops, I must have misunderstood the question.  There's no effect on the
.application file.  It isn't necessary to specify the pages in the
.application file at all.  My entire (small) app that I took the example
from has this (omitting the ?xml and DOCTYPE header lines):

    <application name="jones"
engine-class="org.apache.tapestry.engine.BaseEngine">
    </application>

And I'm not even sure all of that is required.
