Barry Books updated TAP5-2099: ------------------------------ Attachment: 0001-TAP-2099-Add-set-method-that-does-nothing-so-Literal.patch Override the AbstractBinding set method so Literal/Symbol bindings will not throw a read only exception when a parameter field is updated. This among other things allows a mixin to use BindParameter to override the default value of a component parameter. > Update parameters 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, 5.4 > Reporter: Lance > Labels: patch > Attachments: > 0001-TAP-2099-Add-set-method-that-does-nothing-so-Literal.patch, > TAP52099-1.patch > > > Currently, I cannot update a component component parameter that is > initialized with a literal: or symbol: binding from a mixin. If I try to > @BindParameter the param and change 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 the rowsPerPage parameter to Integer.MAX_VALUE. I > can't currently do this because by default, the parameter is a symbol: > binding. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
