I have some pages in my web-app that should display multiple table being updated by lightstreamer.
The fact is, I should stop & start some of them at will via javascript.
The safer way should be changing status to the engine but this would imply having one engine per table and I don't think it's possible.
I tried this way but I alway get this error whenever I create a new engine :

Another way should be having one engine in my page, if I need to stop a table I should remove it from its pushpage. Is it the only way?
