Has something changed with container auto-bind scripts in 3.7?

Since upgrading to 3.7 I just noticed that my containers with auto-bind scripts applied have stopped working (the nodes have been removed).

eg script:
if (
    $node->zoneUIN == 0 &&
    $node->isRouter == 1 &&
    $node->isPrinter != 1 &&
    GetCustomAttribute($node, "ignoreRouter") == null)
    {
      return true;
    }
return false;

But even a simpler version with Zone and other attribute checks removed:
if (
    $node->isRouter == 1)

    {
      return true;
    }
return false;

Will remove any bound node.

The relevant nodes have isRouter = Yes on the object details tab.

Same is happening to all atuo-bind containers (looking at isBridge, or isPrinter etc).

I enabled debug logging on the server, manually bound a router node to the All Routers container with simplified stripped down auto-bind script from my first post and ran a configuration poll.  The autounbind event was triggered and my router removed again.

Below is debug log around the subsequent autounbind event.

Hi,

this is caused by introduction of boolean type in NXSL. If you change

if ($node->isRouter == 1)

to

if ($node->isRouter)

it will work correctly. As those attributes are boolean by nature and all our examples use only second form we didn't expect that they are used with == operator (and == 1 was unreliable anyway because it could have happen to be any non-zero number).

Best regards,
Victor

Thanks Victor, I guess thats a "$node->isPrinter != TRUE" for excluding printers that for some reason also get classified as routers too?

Preferably you should use


not $node->isPrinter

or

!$node->isPrinter


although your form will work too, because isPrinter will contain boolean value TRUE or FALSE, and if it is false then isPrinter != TRUE will produce expected result.

Best regards,
Victor
