From 2ac19881f92c94f4e9427bd9ff513210675f259e Mon Sep 17 00:00:00 2001 From: Ulf Hermann Date: Wed, 8 Jun 2016 17:32:32 +0200 Subject: QML: Only release types if they aren't referenced anymore Just checking for references on m_compiledData is not enough. The actual component can also be referenced. Thus it won't be deleted on release(), but cannot be found in the type cache anymore.
