Can't you use prepareForRender() ?

I thought it should work too - I'm at a loss to work out why it doesn't!
It needs to work this way, rather than the way you suggest, as the
parameter passed to encodedUrl is a specific format string. This string
is used to set the value of between 3 and 30 other parameters on the
class. The encodedUrl value is not stored, but the unpacked values are.
This means it's hard to make it work with an abstract property.

Why would you like to have it called? Maybe there is a better solution
for
your problem.
(For example: create a public abstract String getEncodedUrl(); in
Java
code and use it to access the value bound to the parameter. Or use lazy
initialization for data related to this parameter.)
Besides, for a long time I thought that Tapestry does not allow this kind
of
parameter accessor definition, only abstract accessors. But some weeks
ago I
saw that it is possible in Tapestry 3 as well, like in your example. The
developers can tell you why this is permitted...
As I know, the setEncodedUrl() in your example is not called by the
framework, instead you can call it to set the value of the parameter's
binding (in this case the method should be abstract).
Of course this is not what you want...
