Hello, Wicket users,
Please, help me to find the difference between theese two
ComponentPropertyModel's (inside some Panel):
add(new Label("currencyPayed", new
ComponentPropertyModel<String>("currentPriceSumCurrency")));
and this (inside some border):
border.add(new Label("currencyPayed", new
ComponentPropertyModel<String>("currentPriceSumCurrency")));
I ask because the second one brings me to this exception:
WicketMessage: Exception in rendering component: [Component id = currencyPayed]
Root cause:
java.lang.NullPointerException
