Changing php-service in FD breaks AS3 service class and valueObjects

Question

I used timemachine to restore my project so that I could carefully reproduce this.  Here's the scenario:
I've written a service in php and used the Data/Service wizard in FB to create my valueObject.  The valueObject is called "Setting".
Now I'd like to add a parameter to one of the methods of my service object.  I open up the php script for the service object in FB for PHP.  I enter the new parameter for the function and save the file.
I immediately see that FB has created new valueObjects Setting1, _SuperSetting1 and _Setting1EntityMetadata.
So, I should be able to fix this be adding the required parameter to my data service call AS3.  I add the parameter to the call.  Now what?  I notice that return type in my Data/Services tab has changed from "Setting[]" to "Setting1[]".  So, I should reconfigure the return type for the function call.  I right-click on the function, select Configure Return Type... and then set the return type back to the existing Setting[].
What happens next is I get an error "Unhandled event loop exception java.lang.StackOverfolwError".  After clicking Okay I'm told that I am recommended to exit the workbench.
I can't figure out how to fix this.  I've gone in and manually edited the AS3 class for my service so that it's using the original Setting valueObject.  I can now at least get the project to compile, and it is using Setting, not Setting1.  But the Data/Services tab still shows that the funciton returns data type Setting1[].

Thanks for your inputs. I will look into that construct thingie (:
As for 'Configure Input Types' dialogue, I can also use it in most cases, but some times it's static size isn't sufficient. For example, try adding this function to service:
public function addUserData($username, $firstName, $lastName, $company, $jobTitle,
        $country, $state, $city, $zipCode, $address, $eMail,
        $phone, $cell, $fax, $webPage, $pictureURL) {
On my PC when trying to change values, only one row is visible, and when I try to 'Select Type' for it, dropdown just closes without changing value. It would be nice if we could resize 'Configure Input Types' dialogue when needed... Or maybe just limit the size of 'Operation:' string in that dialogue..
PS. I just played with it for a bit. If you enter too long function name select window completly disappears:
public function abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz($abcdefghijklmnopqrstuvwxyz) {}
