V4MD 2.0.5 Vlink: getIsBetween

[info at vallemediatime.com]

Hi Ruslan,
I'm testing other Vlink method (I see some other problems... but I hope in my mistake)

I've tried to use:
put gDb.link(linkName).getIsBetween(gDB.table(T1), gDB.table(T2))
-2147483645

and not TRUE or FALSE, why?
I'm sure that the link exist.
I must add a integer in T1? but how can I do? 
The new reference is better but don't help me in this case.

In other similar handler the variables: linkName, T1, T2 works
