Re: Grid mixin: grid datasource get instancied on each use

[Lance Java]

As you've discovered... Tapestry replaces field access with Binding.get()
using plastic byte code magic. You can use a local variable to avoid
multiple gets.

Eg:

@BindParameter
private GridDataSource source;

...

GridDataSource sourceCopy = source;
doStuff(sourceCopy);
doMoreStuff(sourceCopy);
