Cannot create PanelCollapsible component programmatically, receive ClassCastException

    Details

    • Workaround Exists:
      Yes
    • Workaround Description:
      The PanelCollapsible class has a typo when it defines the component type. Instead of defining COMPONENT_TYPE, it defines the public static variable COMPONENET_TYPE. If you use the typo variable, it works.

      Description

      The following line in our application fails:

      PanelCollapsible panel = (PanelCollapsible) FacesContext.getCurrentInstance().getApplication().createComponent(PanelCollapsible.COMPONENT_TYPE);

      The exception received is

      java.lang.ClassCastException: javax.faces.component.UICommand cannot be cast to com.icesoft.faces.component.panelcollapsible.PanelCollapsible

        It looks like, when we use the correct variable, it's just creating a UICommand object. Hence, the ClassCastException.

        I scanned through the 1.7.2 SP1 source, and found 11 components that were using the variable name with the typo. When I update the PanelCollapsible source, renaming COMPONENET_TYPE to COMPONENT_TYPE, it works fine.

        I've attached a patch against the 1.7.2 SP1 release of the source that fixes this for the 11 components I found that contained this typo. The patch was built from the icefaces root directory.
