I have strange problem. My facelet uses RichFaces. When I use a4j:commandButton to update some backing bean attributes which should then be outjected and displayed on the page the new value does no get outjected unless i call

Contexts.removeFromAllContexts("categoryName");

Any ideas what is wrong ?

My bean in brief :

@Name("myBean")
public class MyBean implements MyBeanLocal {
    @In(required = false)
    @Out(required = false)
    private String categoryName;
    @Out(required = false)
    private OfferCategory selectedCategory;

    private void setSelectedCategory(OfferCategory category) {
        selectedCategory = category;
        Contexts.removeFromAllContexts("categoryName");
        categoryName = category == null ? "" : category.getName();
    }

    public void processSelection(NodeSelectedEvent e) {
        log.debug("processSelection");
        UITree processedTree = (UITree) e.getComponent();
        selectedCategory = null;
        try {
            setSelectedCategory((OfferCategory) processedTree.getRowData());
        } catch (IllegalStateException ex) {
            setSelectedCategory(null);
        }
        if (processedTree.getId().equals(systemTree.getId())) {
            selectedSystemCategory = (SystemOfferCategory) selectedCategory;
            mapping = null;
        } else {
            selectedExternalCategory = (ExternalOfferCategory) selectedCategory;
            if (selectedExternalCategory != null) {
                mapping = new ArrayList(selectedExternalCategory.getMapping());
            }
        }
    }
}
