Pessoal, eu comecei a mexer com Flex há pouco tempo, e estou tentando usá-lo pra fazer a interface de um trabalho de facul - um webmessenger. Pra manter o código organizado, resolvi customizar alguns componentes, separando a lógica de cada um… Só que por alguma razão, quando eu acrescento meu VBox customizado ao TabNavigator, os labels estão invisíveis e o Rich Text Editor não aceita texto, como se estivesse tudo desabilitado ou com algum erro.
Tenho a impressão de que deve ser algum esquecimento bobo, mas como não conheço muito de Flex, não sei o que está faltando. Segue o código (a parte de mensageria está comentada porque estava testando só a parte gráfica mesmo).
