But same is giving problem when I hover on keyword.

Thanks in advance.

Hello Mr. Christian Dietrich,

Thanks for the reply.
I have gone through the link and it was useful.
There is another scenario where I got stuck.
Need your help in that regard as well.

How can I differentiate whether the hover is on keyword/Token with problems (red underline) or is on keyword/Token which is problem free ?

I need to add more information on hover for the keyword/Token with problems (red underline) . Same will not be applicable for the hover on keyword/Token which is problem free.
This is the reason I want to differentiate between both.

Thanks and regards,
Virag Purnam

Not validation messages.
When we hover on tokens (in case of problem tokens), it displays validation message
when we hover on tokens (problem free tokens), it will not display any validation message.

What I want to know is how to differentiate between these two types?
Any method or class which i can refer?

please give an example of what you are talking about.

and what you want to achieve:
- change error messages
- show tooltips

- problem hover always beats other hover (see org.eclipse.xtext.ui.editor.hover.DefaultCompositeHover - annotation=problem hover first - htmlHover = tooltip second).

you could invert that but then you wont get the error messages.
