iOS Question newbie B4i error

[akinnovation]

Hi all,
I have copied the population app as tutorial for B4X.
When I execute my modified app I get an error

Copying updated assets files (20)

Castelfiorentino*
Empoli*
Montaione*

SignalHandler 11
Error occurred on line: 74 (PreoptimizedCLV)
Signal - 11
Stack Trace: (

)

the row with * are the data from DB.
The code I execute is

Sub SQLQuery(Query As String)
    CLVSearchResults.Clear 'Clear the CustomListView

    Dim SenderFilter As Object = B4XPages.MainPage.SQL.ExecQueryAsync("SQL", Query, Null)
    Wait For (SenderFilter) SQL_QueryComplete (Success As Boolean, rs As ResultSet)
    If Success Then
        
        Do While rs.NextRow 'Loop through the results
            'Ceate your custom type (on a per line basis)
            Query=rs.GetString("descr")
            Log(Query)
            PCLV.AddItem(260dip, XUI.Color_White, CreateRowSearchResultData(Query, Query,Query))
        Loop
        PCLV.Commit
        rs.Close
    Else
        Log(LastException)
    End If
End Sub

the error is generated from the PCLV.Commit execution.

The same error is generated from the original app if I put a breakpoint on PCLV.commit and wait for some second

Thank you to all
Marco

You are sure you have downloaded the PreoptimizedCLV library, right? If yes which version?

Hi hatzisn,
yes I have downloaded the library and use the 1.21 version(the last I think)

Unless you need to show a lot of items then PreoptimizedCLV is probably an overkill.

If you do want to use PCLV then start with example 1: https://www.b4x.com/android/forum/t...extension-for-xcustomlistview.115289/#content
Do you get any error?
