Help for QMetaType

I'm trying to persist the following custom class using JSON:


class StoredProfile: public QObject

	QString m_url;	// or user's account name/email
	QString m_usr;	// or consumer key
	StoredProfile(const QString& url = 0, const QString& usr = 0);
	 StoredProfile(const StoredProfile &p);

 	virtual ~StoredProfile();

	const QString& url() const {
		return m_url;

	void setUrl(const QString& url) {
		qDebug() << "setUrl:" << url;
		m_url = url;

	const QString& usr() const {
		return m_usr;

	void setUsr(const QString& usr) {
		qDebug() << "setUsr:" << usr;
		m_usr = usr;


 When this object is saved using BB JsonAccessData, "null" is written (to the buffer/file).


Does the custom class need to provide other methods to allow JsonAccessData to convert to a QVariantMap?

Re: Help for QMetaType

You can only pass in an actual QVariantMap or QVariantList to the save fucntion on JSON Data Access. You could store the data inside StoredProfile as a QVariantMap and then pass that map into JsonDataAccess.
