Refrence forms in application

Question

Hi All,
Is there any way to know a particular Refrence form is subclasses in these many forms ?
we are having some refrence forms, which are subclassed in main application
forms.
These refrence forms are used to keep common functionality in one form and then we refrence this common functionality in various forms by subclassing these refrence forms.
Whenever we make any change with Refrence Form we need to Recompile the forms which have subclassed it, so that the new changes from Refrece Forms should be subclassed in application form.
But as one refrence form is subclassed in many forms it get's dificicult to locate only those form and then recompiling.
And to compile all the forms is also not a feasible solution.
so is there any way to know a particular refrence form is subclassed in these many forms.
Thanks
Ashish

hi there
Yes, if you're using form 9i/10g you can find out subclassing information of any forms object by making use of JDAPI.
Below is a quick sample that displays a form, block and block item that has been subclass as well as what the parent is. you'll be able to run it for a single form of for a group of forms in a directory. It does not suite exactly what you want as it is but I'm sure you'll be able to modify it to perform what you want.
Cheers
