It depends on the verb. The list you have is incomplete: both leave and declare take adjectives only when they are transitive or in the passive voice. These are called object complements; the list you have gives verbs that take subject complements. I don't know of a list that gives verbs which take object complements.
Why didn't these verbs go on the list you have? Maybe the compiler of the list didn't want to make it too complicated.
Only transitive verbs can be made passive, so these two cases go together.
The grammar gets complicated here. The verb paint can take an object complement, but only if it's a color.
He painted the barn red.
*He painted the barn polka-dotted.
He painted the barn with polka dots.
I think it's worth mentioning some of the complexities involved, though many of these were mentioned at the thread Andrew links to.
Choice of tense probably isn't as clear-cut as we'd like to think. For instance, with disease-related examples as mentioned in the link:
I have diabetes /a cold / occasional headaches / frequent headaches.
*I am having diabetes / a cold.
I am having occasional headaches / frequent headaches.
The use of have as a near-synonym of get / take (punctual) as well as possess / suffer from (durative) is doubtless a complicating factor here.
Turning to the multi-word verb get on, we see that again there is idiosyncratic behaviour dependent upon the particular 'object referent' (whether stated overtly or not):
I hear you've got a new job. How are you getting on? [ie with your new job]
I was sorry to hear that you and Bill had a big argument (last month). How are you
getting on with him now?
I was sorry to hear that you and Bill had a big argument. How are you
getting on now?
and for the do + bare infinitive:
*I hear you've got a new job. How do you get on?
Travelling by bus must be hard for you now. How do you get on? [different sense of get on, of course]
*I was sorry to hear that you and Bill had a big argument last week. How do you
get on (with him) now?
I was sorry to hear that you and Bill had a big argument last year. How do you
get on (with him) now?
There seem to be subtleties involving not only the continuous / repetitive distinction, but also whether the present state can be regarded as steady (involving how long it has continued).

"I am not getting the meaning of your instructions" - no one would ever really say this, it would be, "I don't get your instructions."
Or even, "I don't get what you mean, these instructions make no sense." So I would say get is a stative verb here.
