> Key: MYFACES-990
> URL: http://issues.apache.org/jira/browse/MYFACES-990
> Project: MyFaces
> Type: Improvement
> Components: Implementation
> Versions: 1.1.1
> Reporter: Steve Peterson
> Priority: Minor
> Attachments: typed-value-binding.patch
>
> In the implementation of each UIComponent, the canonical logic for retrieving
> a non-String property is to cast the result
> of the valueBinding.getValue() method to the expected type.
> public boolean isItemDisabled()
> {
> if (_itemDisabled != null) return _itemDisabled.booleanValue();
> ValueBinding vb = getValueBinding("itemDisabled");
> Boolean v = vb != null ? (Boolean)vb.getValue(getFacesContext()) :
> null;
> return v != null ? v.booleanValue() : DEFAULT_ITEMDISABLED;
> }
> Yields an obscure stack trace that doesn't yield the ID of the component or
> the property that is being referenced:
