I'm using the very simple code from this page in my theme's function.php file
http://gravityhelp.com/documentation/page/Gform_field_value_$parameter_name
But its not working at all. I want to fill out the default value via Hook. Its working via QueryString and Short Code. I'm using OptimizePress theme. It does not throw any error but keeps the field value NULL.
We're going to need more information to help you with this. Can you post your functions.php at pastie.org or pastebin.com, then post a link to your web page with the form. And show us how you're populating the field, including the parameter name.
Note the parameter name is case sensitive.
Thanks.
Here is the code:

Form is in private area so cannot give you link of form but its just a simple form and I'm following all steps as in:
http://gravityhelp.com/documentation/page/Gform_field_value_$parameter_name
Based on what I see here, I cannot explain why it's not working. If you export the form and post a link to it, I can take a look at it.
Where does the value MyApp come from? Are you always setting the value of app to MyApp? You mentioned that it works via query string and shortcode. How is it supposed to work when you use the filter? Will it always be set to MyApp?
