Ottenere "Portlet Portlet_WAR_portletID ha un portlet null" in liferay 6.2

Question

Ho creato un progetto portlet plugin liferay e distribuito in Liferay 6.2. Quando provo a distribuire, sto ricevendo errore "Portlet Portlet_WAR_portletID ha un sacchetto portlet null". Non riesco a trovare la radice come ho potuto vedere mi riferisco al progetto di plugin corretto.

Answer 1

Ridistribuire nuovamente il portlet. Ho affrontato lo stesso problema. Interrompo il server e poi pulisco il mio portlet, quindi ho avviato il mio server. Quando ho effettuato il check-in del browser, ho ricevuto il server interno e nella console "il portlet contiene un sacchetto null". Ho schierato di nuovo e sta arrivando perfettamente.
