ActiveIndex из TabView не обновляется
У меня следующая проблема.
Существует TabView с 3 вкладками. В каждой вкладке у меня есть две таблицы данных. Если я выберу строку в первой таблице, связанные данные будут загружены во вторую таблицу. Например (псевдокод):
<form>
<tabview>
<tab>
<datatable>
(data in table A)
<datatable/>
<datatable>
(data that is dynamically loaded if one row in table A is selected)
<datatable/>
<tab/>
<datatable>
........
<datatable/>
<datatable>
........
<datatable/>
<tab/>
<tab>
<datatable>
........
<datatable/>
<datatable>
........
<datatable/>
<tab/>
<tabview/>
<form/>
Если я выбираю элемент в первой таблице (таблица A), соответствующие данные загружаются во вторую таблицу (как в примере выше). Но прежде чем я смогу переключиться на другую таблицу, я должен явно отменить выбор выбранной строки в первой таблице, чтобы activeIndex обновлялся и происходило событие отмены выбора в компоненте поддержки, которое очищает связанные данные во второй таблице. Если я не делаю этого отмены, мой activeIndex из вкладки не обновляется, и я получаю это сообщение об ошибке.
