Defect #969
NPE on service call
0%
Description
I have a module with a bunch of service calls. When I run the module (in developer) I can call the services without any problems.
The moment I link the module to my main solution (in developer) I suddenly get the following NPE.
java.lang.NullPointerException

The thing is that invokeService is expecting the service definition to be in the main solution.
Perhaps I could add a 'solution' parameter to the invokeService() call, although I wonder where I should place it as Java might confuse it with the parameters Object (a String being an Object), so it's a little tricky.
In any case it should work if you place your "services" json in the main solution in config.json
You could to do it in a more reusable way by putting your services definitions inside a separate file alongside the config.json file and then place a #parse("services.json") (or #include() if you're not using any dynamic variables in there) at the place where your services should be.

Ah, I knew I was overlooking something. The solution name.
The #parse("services.json") approach works for me, thanks!
Perhaps the plugin can give an error msg that says that the solution/service combo is not available in the config.json?
