Pessoal,

tentei escrever um  código bem simples, baseado num tutorial que segui, para exercitar o uso de set e assessmentStatement. Porém quando peço para executar no Virtual STB com Ginga-NCL 0.10 a aplicação nem começa e já para.

A aplicação deveria se comportar assim: mostra um vídeo junto com uma imagem. Se durante a exibição do vídeo o usuário aperta a tecla verde, a imagem deve ser escondida (stop) quando o vídeo terminar. Caso contrário, a imagem continua sendo mostrada sobre o fundo preto.

Não consegui ver na saída (abaixo) nada que pudesse me dar uma pista do que pode estar acontencendo.

o documento é exibido corretamente, mas naturalmente não esconde a imagem.

Alguém tem alguma idéia do que possa estar acontecendo?

Valeu!
