Hi,
When do I use names with spaces? There might be (example given) a code like:

/* dmxServerAction name "Immo Insert Executor" */
       jQuery.dmxServerAction(
         {"id": "Immo Insert Executor", "url": "../dmxConnect/api/Immo Newinsert.php", "form": "#ImmoInsert", "data": {}}
       );
  /* END dmxServerAction name "Immo Insert Executor" */

On linux servers this might be a problem. In your tutorials you are using syntax wih and without spaces - some of them are turned into php files with or without spaces.

Would you recommend to always use "spaceless" names?

Hello Greta,
There shouldn't be a problem to use names with spaces for the executor names - it is tested and working.
I personally prefer not using spaces though, but writing "ExecutorName" instead, but that is just my personal preference.
