Unblessed problem when passing structures as agrument

loris has asked for the wisdom of the Perl Monks concerning the following question:

Hello Blessed and Blessing Monks,

I want to do something like:


my $node = $self->makeMyNode('Blorp')
$self->addMyNode($node);

...

sub addMyNode {
  my ($self,$node) = @_;

  my $parentNode = $self->generateParentNode($node);
  $parentNode->addChild($node);
}
[download]

but I get the error

XML::LibXML::Node::addChild() -- nNode is not a blessed SV reference a
+t ...
[download]

I assume I must do bless at some point, but I am not clear how. Should I be passing a reference and then blessing that?

Thanks,

loris

Your error message indicates that there's a lot more to the problem than your code snippet is demonstrating. Please provide a complete, but minimal, testcase that I can cut'n'paste and run on my computer, otherwise I'm not sure any of us are going to be much help. Remember - I'm not sitting next to you, so you have to provide enough information for me to replicate your problem. My criteria for good software: Does it work? Can someone else come in, make a change, and be reasonably certain no bugs were introduced?	[reply]

Oops, sorry, I thought I was making some fairly elementary Perl blunder that my example would illustrate. It turns out that in fact the function I thought was giving me the parent node was in fact incorrectly returning an integer. Doh. I shall look a bit harder myself before posting again next time. Thanks for the interest anyway.
