Problem with persistent class registration

[Guest]

Hi,

I tried to use the example provided in the FAQ to update my database schema based on the persistent classes registered in the context.

My application crashes when this line is executed in the updateDatabaseVersion() function:

Code: Select all

qx::QxCollection<QString, qx::IxClass *> * pAllClasses = qx::QxClassX::getAllClasses();

I debugged a little and what is making it crash is the assert in the registerAllClasses() function:

Code: Select all

while (itr.hasNext())
   {
      itr.next();
      IxClass * pClass = QxClassX::getClass(itr.key());
      qAssert(pClass != NULL); Q_UNUSED(pClass); // <--- this line
   }


Apparently the classes are not registered correctly, or maybe I forgot to do something (application is working just fine though, I just have problems with introspection).

What could be the problem?

Thanks.

A few more details:

I think it is due to the fact that I'm using a namespace: when calling

Code: Select all

bool QxClassX::insert(const QString & sKey, IxClass * pClass)

the key is "foo::bar::MyClass", but in the registerAllClasses() (when the getAllClasses() is called):

Code: Select all

IxClass * pClass = QxClassX::getClass(itr.key());

the key in this case is "MyClass", so the pointer is always NULL.

Hi,

I think it is due to the fact that I'm using a namespace...
...the key is "foo::bar::MyClass"...
...the key in this case is "MyClass", so the pointer is always NULL.

For classes into namespace, there is a Q&R in the FAQ : http://www.qxorm.com/qxorm_en/faq.html#faq_150
And you have an example of namespace with CPerson class into './test/qxDllSample/dll1/include/' directory.
You should try to compare your class with the example CPerson class.

Could you provide please your full source code of your 'foo::bar::MyClass' class (*.hpp and *.cpp files) ?

Actually I found my solution. My problem was that I thought that this would work:

Code: Select all

using namespace foo::bar;

QX_REGISTER_COMPLEX_CLASS_NAME_CPP_SM_INSPECTOR(MyClass, foo_bar_MyClass)


but it had to be:

Code: Select all

using namespace foo::bar;

QX_REGISTER_COMPLEX_CLASS_NAME_CPP_SM_INSPECTOR(foo::bar::MyClass, foo_bar_MyClass)


So I just didn't think of adding the namespace in the macro. Thanks anyway!
