listActionInfos() returns a tuple of ActionInfo objects, getActionInfo() 
the first ActionInfo that passes the checks. Note that ActionInfo is a 
dict, not the persistent Action object you need.

It returns the first 'view' Action it finds.

Not quite sure, but I guess you have problems to get a useful expression 
context.

Once again:

getActionObject(action_path) is the method you are looking for.

ti.getActionObject('object/view') should work for you.
