I have the following problem.
There is a TabView with 3 Tabs. In each Tab I have two DataTables. If I select a row in the first table, associated data will be loaded into the second table. For example (pseudo code):
<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/>
If I select item in the first table (table A) the associated data is loaded into the second table (as in the example above). But before I can switch to another table, I have to explicitly deselect the selected row in the first table, so that the activeIndex gets updated and my deselect event in the backing bean will be fired which clears the associated data in the second table. If I don't do this deselection, my activeIndex from the tabview is not updated and I get this error message.
