Jesse Kuhnert resolved TAPESTRY-883:
------------------------------------
Resolution: Invalid
> PropertySelection uses wrong value compared to model for equals() check
> -----------------------------------------------------------------------
>
> Key: TAPESTRY-883
> URL: http://issues.apache.org/jira/browse/TAPESTRY-883
> Project: Tapestry
> Type: Bug
> Components: Framework
> Versions: 4.0
> Reporter: Curtis Paris
>
> If your IPropertySelectionModel returns a different Value than Open for a
> given index, the PropertySelection does not work.
> In PropertySelectionModel::renderFormComponent, we are calling "getValue()"
> for the value. This is returning the HTML Form value that is set. It does
> NOT return the object that we are comparing to.
> > Object value = getValue();
> But, right down below we are calling model.getOption(). This returns the
> actual object that is represented by the index.
> > Object option = model.getOption(i);
> So, now we have a value, and are trying to do an equals(value, option) which
> never returns true.
> The rewindFormComponent is doing it somewhat right. It is getting the
> parameter value, and then doing a "model.translateValue(value)" which returns
> the option object. But, there is no simular functionality for when the value
> is set clean from the form.
