---------------------------
Summary: Update values bound to literal: or symbol: from a mixin
Key: TAP5-2099
URL: https://issues.apache.org/jira/browse/TAP5-2099
Project: Tapestry 5
Issue Type: Improvement
Affects Versions: 5.3.6
Reporter: Lance
Currently, I cannot update a component value that is initialized with a
literal: or symbol: binding. If I try to @BindParameter the component parameter
and set it's value, I get a "Binding %s is read-only" exception (originating
from AbstractBinding).
I propose that literal and symbol bindings are sourced from a PerThreadValue
that can be updated by a mixin.
My original need for this was to create a "SinglePage" mixin for the Grid
component which would set rowsPerPage parameter to Integer.MAX_VALUE. I can't
currently do this because by default, the parameter is a symbol: binding.
