When I add existing units/forms (originally created in other project) to a new project, those forms are not shown in the list of units/forms which can be inherited.
Here is the step to reproduce the problem:
1. Create a project1 with 2 forms (blank forms are enough):
unit project1_unit1, form name: TFormProject1Form1
unit project1_unit2, form name: TFormProject1Form2
2. Create a project2 with just 1 blank form.
Add files from project1 above:
project1_unit1.pas
project1_unit1.lfm
project1_unit2.pas
project1_unit2.lfm
3. Try to inherite a new form:
File -> New... ->Inherited project component
You'll see the forms which just added are not shown in the list.
Environment:
Lazarus 2.0.12
O/S: Linux ubuntu 18.04 64bits
Do I miss something or is it a bug?
Attached are zip for those 2 projects, if you want to try, just extract the zip and do the step 3
