eu não posso mandar valores para minha tag lib desta maneira ?

olá,

não conheço essa taglib, mas talvez o atributo "total" dela não aceite valores definidos em tempo de execução...

para se certificar, verifique dentro do arquivo .tld se o valor da tag <rtexprvalue> para o seu atributo é true ou false...

se for false, então você nao pode colocar variaveis dinamicas (como vc esta tentando fazer), apenas literais e constantes... se for true, entao nao sei te informar qual é o erro hehehe

essa taglib é minha... to tentando fazer uma paginação meio estranha afinal... as taglib que encontrei na web não se "adaptam" ao sistema q trabalho.

sua dica funcionou, valeu.
