Re: Problem with gb.web.gui in Gambas 3.21

[Safiur Rahman <isafiur@xxxxxxxxx>]

Hi

Can you explain me about this strange behavior in gambas 3.21 gb.web.gui?
The following problem appears when WebTable gets selection back after
closing a modal WebForm.


A) This doesn't work

Private Sub ShowTable()

  $hres = $con.Exec("SELECT fldvalue FROM tbltest")
  $aMyFields = New String[]
  ReadSmallData(WebTable1, $hres, $aMyFields)

End

Public Sub ReadSmallData(GridView1 As WebTable, hres As Result, aFields As
String[])

  Dim rxf As ResultField

  GridView1.Clear()
  GridView1.Columns.Count = hres.Fields.Count
  GridView1.Count = hres.Count
  For Each rxf In hres.Fields
    aFields.Add(rxf.Name)
  Next

End

Public Sub WebTable1_Data(Row As Integer, Column As Integer, Data As
WebTableData)

  $hres.MoveTo(Row)
  Data.Text = $hres[$aMyFields[Column]]

End


B) Strangely this works

Private Sub ShowTable()

  $hres = $con.Exec("SELECT fldvalue FROM tbltest")
  WebTable1.Clear()
  $aMyFields = New String[]
  ReadSmallData(WebTable1, $hres, $aMyFields)

End

Public Sub ReadSmallData(GridView1 As WebTable, hres As Result, aFields As
String[])

  Dim rxf As ResultField

  GridView1.Columns.Count = hres.Fields.Count
  GridView1.Count = hres.Count
  For Each rxf In hres.Fields
    aFields.Add(rxf.Name)
  Next

End

Public Sub WebTable1_Data(Row As Integer, Column As Integer, Data As
WebTableData)

  $hres.MoveTo(Row)
  Data.Text = $hres[$aMyFields[Column]]

End


Both of the methods worked well in gambas 3.20. Attached a project to
replicate this problem.
