If you’ve already upgrated to the latest Forms version (currently 12.2.1.2) you’ve maybe encountered following problem:
If you use a cursor, that is specified in a package specification within your forms and define a rowtype based on that cursor that is fetched into the rowtype in a different other part of the form (in my case the package body). If you then try to compile you may get the error 801 internal error [unexpected fragile external reference] from figure 1.

Metalink documents

We’ve opened a service request for that problem in metalink and received an answer, that I would like to show you in this blogpost. There is also a bug filed as well: Bug 23250870
The solution for the compilation error and it’s solution is described the following document in Metalink:

Rather than providing a patch for that problem, Oracle gives the information, that you have to set following variable to one to enable the compilation:

FORMS_PLSQL_BHVR_COMMON_SQL=1

If you set a path variable in CMD before starting the Forms Developer and then execute frmbld.exe you are able to compile a module that contains a construct like:

PACKAGE Test IS
  cursor c1 is select name_object from all_obj;
  master_rec            c1%ROWTYPE;
END;
Package body Test is  
  Procedure p1 is
  begin
      fetch c1 into master_rec;      
      close c1;
  end p1;    
end;  

 

Registry entry & environment variable

Warning: Changing the Windows registry can mess up your OS.

I’ve tried to also create a registry entry in a Windows machine under HKEY_LOCAL_MACHINE\Software\Oracle\KEY_OracleHome1 and set it to “1” so you don’t have to execute a batch before running Forms Builder. Also I have tried to create a new environment variable. Both options enable the Forms Builder to compile. But I had complications while compiling a bigger customer forms module, when I hit directly Ctrl+shift+k – the Forms Builder crashed when I did not connect to the database before hitting the hotkey.
