[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-1355) ConverterChain.getAsString behaves incorrectly if the input is String already

    [ http://jira.jboss.com/jira/browse/JBSEAM-1355?page=comments#action_12363261 ] 

Sergey Koshcheyev commented on JBSEAM-1355:
-------------------------------------------

There seems to be a similar problem in getAsObject as well - since there is no converter in the chain to convert from String to String, it returns null instead of the value itself.

> ConverterChain.getAsString(FacesContext context, UIComponent component, Object value) will return null if value is String already. It should cast the value to String and return that instead. Proposed fix: change
> String output = null;
> to
> String output = value instanceof String ? (String) value : null;
> This happens when UIComponent.value is bound to a String property. In this case no "final" converter will be added to the chain, so output will be null after the loop in getAsString.
