Description:
------------
So far as I can tell this problem is trigged by the serialisation/deserialisation
going on in the inheritance hierarchy (ParentA and ParentB) in combination with
the re-use (triggering obj references in the serialisation) of ParentB's children
in Wrapper.
At a guess this is a difference in the table construction between serialize and
unserialize (thus ending up referencing the incorrect thing), but I haven't yet
taken a look at their implementation so that's a total stab in the dark.
Test script:
---------------
http://pastie.org/private/vbjpi8ytmqqxi2pkiizatw
Expected result:
----------------
object(Wrapper)#6 (2) {
["parent"]=>
object(ParentB)#7 (2) {
["collection"]=>
array(3) {
[0]=>
object(Child)#8 (1) {
["property"]=>
string(3) "foo"
}
[1]=>
object(Child)#9 (1) {
["property"]=>
string(3) "foo"
}
[2]=>
object(Child)#10 (1) {
["property"]=>
string(3) "foo"
}
}
["rofl"]=>
string(3) "foo"
}
["children"]=>
array(3) {
[0]=>
object(Child)#8 (1) {
["property"]=>
string(3) "foo"
}
[1]=>
object(Child)#9 (1) {
["property"]=>
string(3) "foo"
}
[2]=>
object(Child)#10 (1) {
["property"]=>
string(3) "foo"
}
}
}
Actual result:
--------------
object(Wrapper)#6 (2) {
["parent"]=>
object(ParentB)#7 (2) {
["collection"]=>
array(3) {
[0]=>
object(Child)#8 (1) {
["property"]=>
string(3) "foo"
}
[1]=>
object(Child)#9 (1) {
["property"]=>
string(3) "foo"
}
[2]=>
object(Child)#10 (1) {
["property"]=>
string(3) "foo"
}
}
["rofl"]=>
string(3) "foo"
}
["children"]=>
array(3) {
[0]=>
object(Child)#9 (1) { <-- Where'd #8 go?
["property"]=>
string(3) "foo"
}
[1]=>
object(Child)#10 (1) {
["property"]=>
string(3) "foo"
}
[2]=>
string(20) "1Y" <-- Unexpected
}
}
