p：selectOneMenu在Primefaces 3.4.2中出错

Question

I recently updated Primefaces from 3.4 to 3.4.2 and now I have problems on some pages where there is p:selectOneMenu component. I see error in JavaScript console which says: TypeError: e.offset(...) is undefined . This error is logged immediately on page loading.

Does anyone know what is a problem?

Answer 1

OK, after a lot of time a finally figure out what's happening. In Primefaces 3.4.2 behavior of p:selectOneMenu is changed little bit, in that way that change event is fired immediately after page is loaded. This problem is manifesting when we have completely empty p:selectOneMenu , which means value of f:selectItems is null, and there is no f:selectItem for empty option. In that case we can see error TypeError: e.offset(...) is undefined in console and javascript is from that point useless, and nothing works any more. For now it has to be empty f:selectItem , or at least one element in f:selectItems .
