The problem comes up when you’re working with Entity selections, where your
time fields are converted to longints. Then Type or Value type of an Entity
instance value does not match the field type.
There’s a problem with Arrays in a Collection. Type returns 0, longint,
because 4D Array variable
Julio,
Yeah, date and time are a 4D thing really. I never store time values as
'time' anyway - always string. Frequently the same for dates.

Thanks John

New command, Value type:
$type:=Value type($col[0])
And note if you use the new For each loop in version 17, all collection
elements must have the same type.

If I'm iterating through a collection how can I get the type of an element?
Here are some results from current attempts:
$col:=New collection(New object;123;"XYZ";New collection)
$type:=Type($col) // type = 42
$type:=Type($col[0]) // err: 4D was expecting a field or variable or
parameter
Yes, I thought this was interesting. A useful change, but no compatibility
setting for this - all previous code that used OB Get type will need to be
updated for version 16R/17. OB Get type can now return Is Date for dates, but
it has a compatibility setting where it can be controlled.
Also
Object get type has been changed in 16r something. Probably when
collections were introduced in r4 but I wasn’t paying attention.
The change is it no longer returns the ‘Object Array’ type (39). Any value
that begins with a [ is interpreted as ‘Is collection’ (42).
Object arrays still work just
7 matches
