iOS Question Strange behavior when loading a layout

I am creating an item for xCustomListView (Version: 1.73). If the view-file exists, there is an error on a complete different codeline in another sub:
 Dim iPunkteMax As Int = modG.GetDBInt("SELECT MAX(Nr) FROM GameTask WHERE [GameTyp] = " & tGLT.gametyp & " AND [Versuche] >= 0")
But if it does not exists, the IDE gives a warning (codeline 4 is underlined) but it works.

Sub CreateListItemRhythmus(btm As Bitmap, score As Int, rhythmus As String, Width As Int, Height As Int) As Panel
    Dim p As B4XView = xui.CreatePanel("") 'Dim p As Panel
    p.SetLayoutAnimated(0, 0, 0, Width, Height)
    p.LoadLayout("viewItmTaskRhtm") '<--- this works only, if the file does not exist
    lblNr.Text = score
    lblItmInfo.Font = Font.CreateNew2("Rhythms", 20) ' lblItmInfo.Typeface = tf
    lblItmInfo.Text = mDrum.GetRhythmusString(rhythmus, True, True, False)
    Return p
End Sub

Update: Now it works! After writing this report, I wanted to copy the error-details, but everything is OK. :) Anyhow I will post it now. May be, there is an simple answer for that behavior. How can a viewfile be loaded, only if it does not exist in the file manager? I remember, that sometimes I had to delete and reinstall my app, because of file management in the iOS device. Is that the same issue?
