I think i found the answer... This code forms a component used in an accordion has as it child, there are two of these in the accordion. whats happening is when the accordion is created the child hidden gives me this error, while visible one works fine ... i think that until this second child is visible, the repeater (rep) never gets a valid instance and the 'arrivedDS' function can't do its thing. any ideia about how to solve this??? some help would be excellent thanks a lot cheers
