Troubleshooting revIgniter library functions

[Ralf Bitter]

Hi Keith,  

in addition to Andre’s valuable tips I would like  
to comment that your approach should actually work,  
but be advised to make sure you include your custom  
library as described here:  

https://revigniter.com/userGuide/general/creating_libraries.html  

Furthermore you can leave your function as is i.e.  
call your library function within your DocLogin.lc controller like:  

	put myDocLoginHandler() into gData["doc_token"]
	
For debugging purposes make sure the logs folder is writable,  
set the gConfig["logThreshold"]  in config.lc to 4 and check the  
log file in case something goes wrong.

The desktop stack includes a single function stack script that logs into the KB server as a proxy ‘public user' and returns an access token string for subsequent page requests.
