Explode Command & SSGET

[steelcitymetal]

If I use:

(command "erase" (ssget) "")

all objects I select are erased.

However, if I change it to:

(command "explode" (ssget) "")

only the LAST object that was selected is exploded.

What is going on here?  Why is it not exploding all items selected?

Edit: The object type I am testing this on are closed polylines.

Obviously I plan on adding more to this, but here is the "full" code which is not exploding all selected objects (only the last object selected):

(defun c:xc()
(command "explode" (ssget) "")
)

There are different command versions that can be invoked. Before calling explode set the command version to 2

(initcommandversion 2)
(command "explode" (ssget) "")

That works, thanks.

To set it back, do I just use (initcommandversion) ?

initcommandversion applies only to the command that follows. It should go back to current version right after the command ends. You shouldn't have to do anything.
