This is a common issue, but he could not find a quick solution so I wrote one.
This function fetches the parent component which in his case was a form containing
<h:inputText/> components, and then clears them. You may need to add some more code to do it recursively if the components are nested.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | public String clear(final String parentComponentId) { UIViewRoot view = FacesContext.getCurrentInstance().getViewRoot(); UIComponent fc = view.findComponent(parentComponentId); if (null != fc) { List<uicomponent> components = fc.getChildren(); for (UIComponent component : components) { if (component instanceof UIInput) { UIInput input = (UIInput) component; // JSF 1.1+ // input.setSubmittedValue(null);// input.setValue(null);// input.setLocalValueSet(false);// input.setValid(true); // JSF 1.2+ input.resetValue(); } } } return null; } |
