If you try to set Url for JSon layer in design time, you will get EAccessViolation. I guess it is by reason of the following code in TIWCGJQMapQueryLayerJSONOptions.SetUrl() method
- Code: Select all
if csDesigning in TControl(Owner).ComponentState then exit;
if not CGIsHttpLink(LUrl) then
begin
WebApp:= GGetWebApplicationThreadVar;
LBaseUrl:= CGGetRequestFullUrl(WebApp.Request,WebApp.AppID);
LUrl:= IncludeURLPathDelimiter(LBaseUrl) + CGRemoveSlash(LUrl);
end;
because actually TIWCGJQMapQueryLayerJSONOptions' Owner is TIWCGJQMapQueryLayer and it isn't derived from TControl, so (csDesigning in TControl(Owner).ComponentState) always returns false.
