Hi,

my problem:
When I want help and click on the help, I have an Error box and a box loading... but no help.

Thank for your help.

Thanks for your help.

Hi Manu,

Help documentation is stored remotely on Serotonin servers, and is requested each time you open a help window. The URL from which the request is made is found in your WEB-INF/classes/env.properties file against the property called "grove.url". Normally this value should be http://mango.serotoninsoftware.com/servlet.

The error you received, "host parameter is null", indicates that your value is not properly set. Please have a look and report back what you find.

Hi

I also have the same problem, I've changed the line in the env.properties file to the URL and noe get this

Error retrieving Mango IdInvalid response code: 404

Cheers

Keith

We found a problem in the build script for the Open version that is not properly setting values in the env.properties file. A new build has been created which fixes the problem.

User with the old build can do one two things:
1) Easiest: download and install the new build (not the "upgrade" version).
2) Quickest: modify the WEB-INF/classes/env.properties file to contain the following (overwriting the existing properties except for "db.url"):

doc.url=http://mango.serotoninsoftware.com/servlet/mangoDocumentation
grove.url=http://mango.serotoninsoftware.com/servlet

Ok I did the install of the new version but am still getting the same error.

The lines in the file are below and look correct.

Rgds

Keith

I should have mentioned that you need to restart the application. If you did, what happens when you hit the URL with a browser on the same machine?

For this

http://mango.serotoninsoftware.com/servlet/mangoDocumentation

i get

{"responseMessage":"Missing document id","responseCode":400,"version":1}

and for this

http://mango.serotoninsoftware.com/servlet

I get your home page

As odd as it sounds, that is in fact the correct response. It implies that the requests can be successfully made from that machine.

So, you get the stack trace that manu reported above?

Thanks. Now I can read the help.
I modify
doc.url=http://mango.serotoninsoftware.com/servlet/mangoDocumentation
grove.url=http://mango.serotoninsoftware.com/servlet
