Hi, Maciej.
Thank you very much for your answer.
There is perhaps an issue on firewall side, so I copied the file locally on my server.
When looking at repositories structure, only Google calendar matches what you explained.
I don't understand how is the structure behind (for Twitter by example) when a welcome page is displayed (is it hidden ?)
So, I can see only this service node after coying its elements on a directory of the server I work on.
I succeeded in creating an other with similar structure, but
when double clicking on a line of service nodes displayed I get an error message 'Failed to install the repository assets'.
So, is it possible for you to send me a complete example of service node with its repository (sub repositories if necessary) contening all the files (index.conf, Directory : .wid, .gif, default handler : file and location, documentation, dependancies : file(s) and location, please ?
Best regards,
David.
