B4J Question [ABMaterial] ABMTable - properties and events of components in cells

[orynkanov]

Hello!
If I add components to the cell, for example ABMCombo, I can not get the selected GetActiveItemId. When accessing ABMCombo.GetActiveItemId error - at com.ab.abmaterial.ABMCombo.GetActiveItemId (Unknown Source). But at the same time I can read the Tag property without errors.

Sub tblUserTable_Clicked(PassedRowsAndColumns As List)
    Dim tblCellInfo As ABMTableCell = PassedRowsAndColumns.Get(0)
    Dim tbl As ABMTable = page.Cell(1,1).Component(tblCellInfo.TableName)
    If tblCellInfo.Column = 5 Then
        Dim comboCloudStorage As ABMCombo = tbl.GetComponent(tblCellInfo.Row, "comboCloudStorage")
        If comboCloudStorage <> Null Then
            Dim UserUid As String = tbl.GetString(tblCellInfo.Row, 0)
            Dim UserLogin As String = tbl.GetString(tblCellInfo.Row, 1)
            Dim intComboId As Int = comboCloudStorage.GetActiveItemId.SubString(2) 'error
        End If
    End If
    tbl.Refresh
End Sub

Also how to receive events for components in cells?
