Summary0017814: Using TAChart component in form causes mistakes in *.lfm file (Win64 only)
DescriptionUsing the TAChart component in a form will produce mistakes in *.lfm file of that form when saving the form unit. After re-opening the project file / unit the TAChart and all components included after that are not restored. An inspection of *.lfm file shows that they are not svaed into.

This behaviour is only under Win64 (Vista, W7) not under Win32. A relation to special GUI appearance (Aero) is assumed but cannot be confirmed.
TagsNo tags attached.

Are any float properties of type extended streamed?

No, but there are properties of type Double

Just discovered: There is an alternative behaviour. Instead of ignoring TAChart in saving, the following box appears:

"Kann binären Komponentenstream von >FormVariable< von TFormVariable nicht in Text umwandeln. Division by zero"

in English:

"Could not transform binary component stream into text. Division by zero"

Any helpful?

Can you get a stack trace?

Sorry, don't know how (can you tell me?). But I discovered that this behaviour is also linked to other components using direct canvas methods (e.g. GLScene). I got them to work by disabling the manifest themes under Project Options. Maybe this is the reason for it since lazarus is compiled with the "Using manifest themes" options?
