Hi All,

Есть такой код на форме:




Почему-то метод removeMultipleValue() при клике на первый линк вызывается, а при клике на линк из цикла - нет.

Что я делаю не так?

забыл никзамени на a4j:repeat, не зря же его сделали про готовом ui:repeat
Заменил, теперь при нажатии на линк вне цикла цикл отрисовывается пустым, как и rich:dataTable в моем предыдущем сообщении: www.sql.ru/forum/actualthread.aspx?tid=1019952

При нажатии на линк внутри цикла возикает MethodNotFoundException:

Заменил a4j:commandLink на h:commandLink, все заработало как надо.




Как-то не слава Богу ведут себя a4j-циклы в таких ситуациях...
