[jira] Closed: (MYFACES-921) NullPointerException using inputSuggestAjax with Facelets
[ http://issues.apache.org/jira/browse/MYFACES-921?page=all ]
Mike Kienenberger closed MYFACES-921:
-------------------------------------
Resolution: Invalid
InputSuggestAjaxTag is pretty trivial. There's some code in there to create a MethodBinding, but that's it. You'll need to do the same thing in the facelets tag handler. The only tricky part is that the method signature changes based on the value of maxSuggestedItems, which is unfortunate. If you can't make this conditional statement work with facelets, submit a patch and I'll review it.
if (((InputSuggestAjax)component).getMaxSuggestedItems()!=null) {
MethodBinding mb = context.getApplication().createMethodBinding(suggestedItemsMethod,new Class[]{String.class, Integer.class});
((InputSuggestAjax)component).setSuggestedItemsMethod(mb);
} else {
MethodBinding mb = context.getApplication().createMethodBinding(suggestedItemsMethod,new Class[]{String.class});
((InputSuggestAjax)component).setSuggestedItemsMethod(mb);
}
However, there's no bug here, so I'm marking this as invalid and closing it.

> java.lang.NullPointerException
> at org.apache.myfaces.custom.inputsuggestajax.InputSuggestAjaxRenderer.encodeAjax(InputSuggestAjaxRenderer.java:209)
> It appears that InputSuggestAjaxTag uses its setSuggestedItemsMethodProperty method to set the suggestedItemsMethod property in the component, rather than this being carried out by the component itself.
