All objects that should be placed in the lfm/dfm file MUST be placed in 
the published section in Delphi and Lazarus, because they are only 
streamed if there is RTTI for them for which "published" was created. 
Yes, there are other approaches, e.g. fpGUI has an IDE that has the GUI 
creation in code and of which the IDE parses and modifies the 
"initialization routine" to display a designer form, and another 
possiblity would be - if they'd be implemented in FPC - the extended 
RTTI which allows you to specify that also e.g. private fields have RTTI 
generated and (with an adjusted streaming system) this could also be 
used. But neither Delphi nor Lazarus uses this approach, so you must 
live with that (for now).
