I'm trying to set the text of a TextArea from C++, but it the page is going plain dark ( splash) with no error messages in the logs.

I have tried it in both simulator and Dev Alpha device and same thing happend.

QmlDocument *qml = QmlDocument::create("logger.qml");
	AbstractPane *root = qml->createRootNode<AbstractPane>();
	txtArea = root->findChild<QObject*>("txtName");
//    	QString temp="";//txtArea->text();
//    	temp.append("Text:");
 	txtArea->setProperty("text", "Text:");

	qDebug() << "JSON data loaded OK!";
	Application::setScene(root);

}

If i comment the 'setProperty' line, the empty text area comes just fine.

As you would notice I tried the setText too, but that also failed.

Use TextArea* instead of QObject* in findChild<TextArea*>("textAreaObjectName");

I changed a sample I have that uses a TextArea to use a QString instead, commenting out all TextArea methods and just doing your setProperty line.  This worked fine for me.   I also tried just changing the findChild to findChild<QObject*>.  When my variable is a TextArea*, this gives a syntax error unless I do:

 dynamic_cast<TextArea*>(m_mainPage->findChild<QObject*>("textAreaObjectName"));

So if the previous suggestion is not enough, change your txtArea variable to a TextArea* and check that the findChild actually returns something.

Did you make any progress on this?
