I had to strip a few parameters out and print literals for now. My next

That's why @Environmental private PropertyEditContext context is there. ;)
It is the bridge that takes you to the edited value.
@Property
@Component(parameters =
{ "value=context.propertyValue" })
Ah - (#1) I thought this was going to work - since only one or the other
block would be used at any given time. Since we are using the same java
class for either / or block ... it strikes me that I can't reuse t:id.
It doesn't matter if you use a component or not, they should have unique
t:id's. If they're not unique, they aren't ids. ;) Don't forget that this
is an ordinary page.
Does the corresponding Java class somehow discriminate and use my same
classification property object but with multiple ids? I think I'm
confusing
things - partly because I have little component writing experience.
When you inject a component in a page, you have to tell Tapestry what is
its t:id. The name of the field is one way to do it. The other ones is
@Component(id="someId").
but I'm not sure what to do to get that working. What is a 'translator'
and how do I write one ... and attach it to the context? And ... are
those
appropriate questions?
Instead of trial and error, grap Tapestry's source code and read the
PropertyEditBlocks class. It is where the Tapestry-provided blocks are
declared. They should give you some hints. Use it as a starting point.
but that didn't turn out so well. "Could not convert '
context.propertyValue.name' into a component parameter binding
The return value of PropertyEditContext.getPropertyValue() is Object. By
the way, it is exactly the property you're trying to edit, so there's no
need to reference property names here.
