Autocompletion in Eclipse for DHTMLX Library

hi,
I am trying to add Autocompletion in Eclipse for DHTMLX Library. I followed all the steps mentioned in respective document but it didn’t work.

e.g. When I type “var main_layout = new dhtmlXLayou”, I was expecting it should complete it to dhtmlXLayoutObject but it didnt.
And if later I type “main_” and use ctrl+spacebar it gives me option as main_layout.
Am I missing anything in settings?
Can you please help me in setting this feature?

Thanks

Same scenario works correctly locally.
Be sure that you are using “javascript editor” for the file in question, as javascript auto-complete works only for that editor type.
