B4J Question [ABMaterial] TimeoutException

[jinyistudio]

Hi

I copy some code showing abmtable(as following picture) from demo project. the ide always has a exception as following code when abmtable is showing some seconds later. Why ..!? Do I have missing anything !?

Sub Page_Ready()              
    ConnectPage   
End Sub

Sub ConnectPage()
    'NEW
    ABMShared.ConnectNavigationBar(page)
   
    FirstNames.Initialize2(Array As String("Alain", "Jos", "Paul", "Bertrande", "Julie", "Stephanie", "Bert", "Charles", "James", "Walter"))
    LastNames.Initialize2(Array As String("Bailleul", "Rogiers", "Dougherty", "Rodrigues", "Ostrander", "Kenyon", "Grant", "Klinger", "Sheffield", "Poindexter"))
   
    ' add paragraph   
    page.Cell(1,1).AddComponent(ABMShared.BuildParagraphBQ(page,"par1b", "The Id of a table {B}MAY NOT CONTAIN A _ CHARACTER!{/B}.  This is because of the inner working of nested table and the _ character is reserved.") )
   
    ' create a table
    Dim tbl1 As ABMTable
    tbl1.Initialize(page, "tbl1", False, False, True, "tbl1theme")
    tbl1.SetHeaders(Array As String("First Name", "Last Name", "Sales Profit"))
    tbl1.SetColumnDataFields(Array As String("FirstName", "LastName", "SalesProfit"))
    tbl1.SetHeaderThemes(Array As String("headerfooter", "headerfooter", "headerfooterright"))
   
    ' add some random values
    For i = 0 To 9
        Dim r As List
        Dim rCellThemes As List
        r.Initialize
        rCellThemes.Initialize
        r.Add(FirstNames.get(Rnd(0,9)))
        rCellThemes.Add("nocolor") ' nocoloredit
        r.Add(LastNames.get(Rnd(0,9)))
        rCellThemes.Add("nocolor")       
        Dim Neg As Int = Rnd(0,100)
        If Neg > 50 Then
            r.Add("$" & Rnd(1000, 15000))
            rCellThemes.Add("positive")
        Else
            r.Add("$-" & Rnd(1000, 15000))
            rCellThemes.Add("negative")
        End If
        tbl1.AddRow("uid" & i, r)
        tbl1.SetRowThemes(rCellThemes) ' make sure you have as many items in rCellThemes as in r!
    Next
   
    tbl1.SetFooter("This is a footer that appears on the bottom of the table.", 12,"headerfooter")
   
    page.Cell(2,1).AddComponent(tbl1)
   
    page.Refresh ' IMPORTANT
   
    ' NEW, because we use ShowLoaderType=ABM.LOADER_TYPE_MANUAL
    page.FinishedLoading 'IMPORTANT   
   
    page.RestoreNavigationBarPosition

if bSwitch is false, you still need to add a theme so rCellThemes.size = rCellValues.size

so probably something like:

if bSwitch then
   rCellThemes.Add("nocolor")
else
   rCellThemes.Add("")
endif

 

[amminf]

Not because my intention is to reuse the same rCellThemes list in each line. Is it possible ?

 

[alwaysbusy]

No, it is needed. Note that what you pass in the rCellThemes is just the name of the theme, not the theme itself. They exists already on the browsers side and the only thing that happens is the correct class in the html is set pointing to the Theme.

 

[amminf]

OK thanks. My only intention was to improve the loading time of the table to avoid timeout.

 

[alwaysbusy]

Also try if it works without the extra refresh after a ShowModalSheet as internally, this method already does a refresh so you shouldn't need to do it again. May increase the speed too.

page.ShowModalSheet(cId)
 ' myModal.Refresh  ' <--------------- try to remove this line

 

[amminf]

All this has already been removed, because it seems that when a modalsheet is Dissmiss then it is not shown quickly when a showModalSheet is reinvoked.

Else
     Dim cId As String = "inpSelectorClients"
     Dim myModal As ABMModalSheet = page.ModalSheet (cId)

     Page.ShowModalSheet (cId)
     MyModal.Refresh
     'Page.Refresh
End If
