PWA and TWebEditAutoComplete

WEB TMS WEB Core
1

I am writing a PWA (TMS Web Project) and use the TWebEditAutoComplete component to get a name. The code to fill the controle is:
procedure TformMain.LoadSpeciesList;
var
url: String;
request: TJSXMLHttpRequest;
js: TJSON;
ja: TJSONArray;
jo: TJSONObject;
i, idx: Integer;
speciesname: String;
begin
edtSpeciesname.BeginUpdate;
try
Console.log('Retrieving species...');
edtSpeciesname.Items.Clear;
edtSpeciesname.Items.StrictDelimiter := True;
edtSpeciesname.Items.Delimiter := ';';
WebHttpRequestSpecies.url := c_url + 'getdata.aspx?item=taxa';
request := await(TJSXMLHttpRequest, WebHttpRequestSpecies.Perform);
js := TJSON.Create;
ja := TJSONArray(JS.Parse(request.ResponseText));
for i := 0 to ja.Count - 1 do
begin
jo := TJSONObject(ja.Items[i]);
speciesname := jo.GetJSONValue('Naam');
Console.log(speciesname);
if speciesname <> 'null' then
begin
if i > 0 then
edtSpeciesname.Items.DelimitedText := edtSpeciesname.Items.DelimitedText + ';';
edtSpeciesname.Items.DelimitedText := edtSpeciesname.Items.DelimitedText + speciesname;
end;
end;
finally
edtSpeciesname.EndUpdate;
end;
end;

The names are retrieved from JSON, but when I enter a character in the edit box the following error message appears in the console :

I have the same implementation in a true web application and here the TWebEditAutoComplete works just fine: Caribbean plant species distribution

What's wrong with the PWA?

Could it be this happens when you compile to release mode and not debug mode?

You can now check. Works in debug mode. The popup however does not cover the map, but thats another issue (css thing I guess).

So doesn't work in release mode, but works in debug mode!

Its due to a compiler optimization.
We have implemented a solution for this that will be included in the next update.

Wonderful!
