Delphi form definitions are not compliant to Lazarus forms . Therefore 
if you try to Delphi sources with some modifications to complete a 
compilation successfully it is very likely that you will get the above 
results .

My suggestion would be as follows :

(1) If there are computation parts within Delphi form related procedures
such as click_Button_x and others , move these parts into independent ( 
from Delphi form ) non-GUI procedures as much as possible .

(2) Re-generate your forms by Lazarus and call those independent non-GUI 
procedures from your form procedures . Your Lazarus generated forms will 
work . If they do not work you may ask help from Lazarus users .


Personally I do not have an exhaustive list of features and variables 
one by one comparing Lazarus and Delphi forms and guidelines to complete 
different features . The easiest and shortest way is to generate forms 
by Lazarus .

Since you have a working prototype in Delphi , such a re-design should 
be easy .


Thank you very much .
