I think this was caused by rev1805 for
RHQ-996 and
RHQ-891
Bug
Closed
Critical
NPE in UI code when executing operation
UIComponent initInputsJavaScriptComponent = config.findComponent(INIT_INPUTS_JAVA_SCRIPT_COMPONENT_ID);
FacesComponentUtility.detachComponent(initInputsJavaScriptComponent);
I will wrap it in a null-check:
UIComponent initInputsJavaScriptComponent = config.findComponent(INIT_INPUTS_JAVA_SCRIPT_COMPONENT_ID);
if (initInputsJavaScriptComponent != null) {
FacesComponentUtility.detachComponent(initInputsJavaScriptComponent);
}
