GMMap AfterPageLoaded Endless Loop

问题

I wrote an application using GMLIb a couple of years ago and it has been working up until yesterday. I read the fix, got a key, recompiled the code with v1.5.4 and v1.5.5 and have the same result.

The code is caught in an endless loop at AfterPageLoaded

if First then FGMMap.DoMap;

First is never true.

Is anyone else experience this problem. XE7 on Win7 64

20/05/2017 Removed GMLib. Reinstalled. Compiled and ran the Megademo and the result is the same. An endless loop at AfterPageLoaded.

Created a simple test program using GMMap component and the result is the same.

I've had the same issue, but it seems that it is solved now!It happened at users who had IE 8 version on their machines - but I don't really know, why...

What is important though, is updating the IE to the latest version solves the problem!

Not so much of an answer, but a very similar issue and - I think - a workaround.

Again, this only affects certain machines, most have IE10 installed. My issue is not that First is never true but that it is always true.

procedure TFMain.GMMapAfterPageLoaded(Sender: TObject; First: Boolean);
begin

    if (First) and (PLCount = 0) then    // was just if First then
    begin
        GMMap.DoMap;
        BShowInfo.Enabled := True;
    end;
    Inc(PLCount);
end;

Altering GMMapAfterPageLoaded as above (initialising PLCount to 0 first) seems to give the DoMap call enough time to work properly
