[jira] Commented: (MYFACES-130) x:selectManyCheckbox , if is not items selected, i have NullPointerException

Posted by "Ronald Holshausen (JIRA)" <in...@incubator.apache.org>.

Ronald Holshausen commented on MYFACES-130:
-------------------------------------------

I have the same issue, with jdk 1.5, tomcat 5.5.7 and myfaces 1.0.9

If no checkboxes are selected, then the browser will not post any values back, so the array needs to be initialised to an empty array before hand.
