Compiling errors:
external function eval(s : string) : object;  // Compiler error:  "Expecting : but instead found eval"

Issues with the IDE Editor:
Tab on a blank line does nothing.
Typing on a blank line jumps to the next line.

Doug,

Where are you defining this function ?  The one issue is something that I forgot to mention in the release notes: the "object" type is now called "TExternalObject".  I will update the release notes accordingly.

Workaround: Settings/Editor - make sure to check the "Allow the cursor in…." check boxes.  I'll put a fix for this in build 2.

I have replaced all occurrences of TObject with TExternalObject.

procedure TfmMenu.buSortClick(Sender: TExternalObject);
I receive a compile error on TComponent(Sender) when I reference Sender. What do I need to do to get this to compile?

Richard,

No, this is not correct.  You only need to replace any occurrences of "Object", not "TObject".  "Object" was the EWB 2.x and earlier ancestor class for external classes, whereas "TObject" is the compiler/interpreter-native ancestor class for all non-external classes.

Called right before the implementation statement of the form unit (see below)  


// google charts
external google : TGoogle;
external function eval(s : string) : TExternalObject;    //*** compile error:  "Expected : instead found eval"

implementation

uses MyCommon, Main;

Can you send me the complete unit ?  I think the issue is with the TGoogle declaration - without it the code compiles fine here.

Just a few more...

This compiles in EWB2 but not in EWB3

function TMainForm.PageCloseQuery(Sender: TObject): Boolean;
begin
 if (Sender is TPage) and
   (TPage(Sender).ControlCount > 0) and
   (TPage(Sender).Controls[0] is TForm) and
   (TForm(TPage(Sender).Controls[0]).OnCloseQuery <> TCloseQueryEvent(Nil)) then
   Result := TForm(TPage(Sender).Controls[0]).OnCloseQuery  // **** Error on this line ***
 else
   Result := True;
end;

<<<  Can you send me the complete unit ?  I think the issue is with the TGoogle declaration - without it the code compiles fine here.

To reproduce in your databound example:

1) Add WebDOM in the uses section

2) Add the following code above the Implementation statement:

   // google charts begin
   external google : TGoogle;
   external function eval(s : string) : TExternalObject;
   // google charts end

 else
   Result := True;
end; >>

Okay, this one is a combination of a couple of things:

1) You can't cast nil to a method in EWB 3's compiler.  Just use a nil.

2) The OnCloseQuery call now works (build 7 coming out today), but you need to make sure to pass it the correct parameters, otherwise you'll still get a compiler error.
