Problem with inheritance in portlets

[Dima Zealander]

hi all

I have base page for portlets and some page that inharitances base page.

Base page contains market name (Label)

        public MarketTableBasePage(final PageParameters parameters)
                        throws StringValueConversionException {
                String id = 
parameters.getString(MarketUtils.PARAMETER_MARKET_ID);
                Label label = new Label(MarketUtils.MARKET_NAME, id);
                add(label);
        }

Descendants have concrete market tables (ListView)

        public CurrencyRates(final PageParameters parameters) throws
StringValueConversionException {
                super(parameters);
                WebMarkupContainer marketTableContainer = new
WebMarkupContainer("marketTableContainer");
                marketTableContainer.add(marketTable);
                add(marketTableContainer);
        }

Web page's constructor with parameters is run twice for portlets (as i
got action phase and render phase ) and in CurrencyRates class content
renders correct , but in Base page simply empty label.

How can i avoid this problem?

Thanks , I'll appreciate any advice
