multiple context values
How can I add multiple context values to an actionlink?
For example a productId and a categoryId?

Marcelo has the right answer for Tapestry 5.0.18: you must create a
property of your page to assemble the context values into a List or
array.
In 5.1, there's new property expression syntax for creating a list:
context="[ productId, categoryId ]"

I guess implementing ValueEncoder for ProjectVersion and then
contributing it to ValueEncoderSource, as Filip suggested, would make
your code work.

Thiago and Filip, thank you very much!
Actually, I have an object ProjectVersion with the composite primary key.
So in ListProjectVersionPage I would like to go to EditProjectVersionPage
this way:
public Object onActionFromEditProjectVersion(EventContext context) {
Integer proCodigo = context.get(Integer.class, 0);
Integer vprCodigo = context.get(Integer.class, 1);
projectVersion =
projectVersionService.getProjectVersionFromPK(proCodigo, vprCodigo);
editProjectVersionPage.setProjectVersion(projectVersion);
return editProjectVersionPage;
}
It works fine! But maybe it's not the best way.
Is there any other way to have only one parameter ProjectVersion like this?
public Object onActionFromEditProjectVersion(ProjectVersion
projectVersion) {
editProjectVersionPage.setProjectVersion(projectVersion);
return editProjectVersionPage;
}
Thanks again!

This is a more reusable solution than the one I've suggested before,
so that's the one I recommend. ;)

What about contributing a ValueEncoder that converts between a ProductId
and a String? I haven't needed to work with composite primary keys, so I
can't say if it'd work, but it's worth a shot.

Hi!
Create a method that return a List containig the values thatt comprise the
composite primary key. ;) This works in any Tapestry version.
Use EventContext as the only parameter of onActivate or any other event
handler method.
By the way, in new code, avoid composite primary keys. It's not worth the
trouble.

I have an object Product and it has a composite primary key (ProductId).
How can I put this object Product in actionlink's context value?
Thank's!!!

You need the "list" binding prefix so you can do this:
t:context="list:p.productId, p.categoryId". It's available 2 ways
that I know of:
1. You can add it to your project by hand from http://wiki.apache.org/tapestry/Tapestry5HowToAddBindingPrefix
2. You can get it for free by including the t5components in your
project: http://code.google.com/p/tapestry5-components/

I was just caught by this problem some time ago, and in the tapestry
site they recommend this:
public Object[] getAccountContext()
{
return new Object[] { account.companyId, account.id };
}
Object onActionFromDelete(long companyId, long accountId){
//...
}
<p>
[<t:actionlink t:id="delete" context="accountContext">delete</t:actionlink>
</p>

I think you can separate the values with commas like this:
t:context="p.productId, p.categoryId"
