Evaluate class field inside anonymous method

[Sonjli 6]

Hello,

I hope to be in the right place.

Also, I don't find this behaviour in forum neither in embt quality.

 

I am in debug with a breakpoint inside an anon method and when I try to evaluate a variable (CTRL + F7, mouse over, watches, etc. ) I get a "undeclared identifier" if I use a class field.

 

Example:

 

TmyDM = class(TDataModule)
	Comp: TADOQuery;
    ...
end;

...

procedure ...blabla...;
var
	CompForDebug: TADOQuery;
begin
    Comp.Close;
    Comp.Parameters.ParamByName('test').Value := 100;
    Comp.Open; // <-- Here evaluate "Comp". I get the right thing
	FmyList.ForEach(
    	procedure(const obj: IMyThing)
        var
        	CompForDebugLocal: TADOQuery;
        begin
        	Comp.Close;
            Comp.Parameters.ParamByName('test').Value := 100;
            Comp.Open; // <-- Here evaluate "Comp". I get "Undeclared identifier"
            
            // This doesn't work:
            CompForDebugLocal := Comp; 
        	CompForDebugLocal.Close;
            CompForDebugLocal.Parameters.ParamByName('test').Value := 100;
            CompForDebugLocal.Open; // <-- Here evaluate "Comp". I get "Undeclared identifier"
            
            // This doesn't work:
            CompForDebug := Comp; 
        	CompForDebug.Close;
            CompForDebug.Parameters.ParamByName('test').Value := 100;
            CompForDebug.Open; // <-- Here evaluate "Comp". I get the right thing
            
        end
    );
end;

Comp is captured and I can confirm debugger evaluator is not working.

Declare LComp: TADOQuery in anonymous method and assign LComp := Comp. Then it will work to evaluate LComp....

Ok, thanks. I needed a confirmation.

Same exact behaviour is for inline variables inside anon method... no way to evaluate them during debug.

It's frustrating if you are working with Spring4d or other modern libraries.
