Hello

I found that string properties with REALstandardGetter and REALstandardSetter, defined like bellow will leak:

{"Font", "StartupLinuxFont", "String", REALpropInvalidate,REALstandardGetter,REALstandardSetter, FieldOffset(TableControlData, StartupLinuxFontName)},

In the Dispose Event of the control then the following is called:

REALUnlockString(me->StartupLinuxFontName);

And the following is called in the Init method of the control:

me->StartupLinuxFontName = REALBuildString("Geneva",6);


The property is not connected to anything else nor accessed or touched in any other place.

Now why does it leak ? Is it a bug in REALbasic handling of REALstandardSetter for REALstring ?

I doubt it's the latter -- that code hasn't changed in an extremely long time (before I even started working here). Is your destructor being called?
