Fix missing deref.

[Danack]

Fixes #514

I realise this could do with some tests.

Please can you direct me to a similar existent test to copy and modify, or at least say where an appropriate test might go.

broken test appears not related to change.

Please add unit tests which verify the behaviour of this new code. These tests should fail when your change is not present, and pass when it is.

Tests for this should probably go in ArraysTest.php. You'll see many example tests in the same folder.

@Danack , @erayd , seems like the PR is not needed as such. The issue was in the usage of library.

The validation was run like

$jsonValidator->check($endpointData, (object)$schemaForPath);

Which worked for a single object but not for a array type schema. And the usage should have been like

$jsonValidator->check($endpointData, $schemaForPath);

See updated answer on

Probably a thought, that you should have some check that people don't mix stdClass and array or something that could be just documented to avoid such issues in future

@tarunlalwani Well spotted - thanks. I've had a play with the code in #514, and it seems that aliasSchema() (function in the test code used to reformat the swagger input) is causing the problem by returning assoc arrays instead of objects. If it's adjusted to return an object, then the validator behaves as expected.

I'll close this PR as it was based on me being dumb.
