Ooops - forgot to mention where findObjects comes from.

This reproduces the bug:
#include <QtGui>
#include <QtScript>
class MyTest : public QObject {
Q_OBJECT;
public:
MyTest (QObject * parent) : QObject (parent) {}
virtual ~MyTest () {}
Q_INVOKABLE QObjectList findObjects (const QString & className) const {
QObjectList result;
QObjectList list = qFindChildren <QObject *> (this, QString ());
foreach (QObject * obj, list) {
if (qstrcmp (obj->metaObject ()->className (), className.toAscii ())
== 0) {
result.append (obj);
}
}
return result;
}
};
#include "main.moc"
int main(int argc, char **argv)
{
QApplication app (argc, argv);
QScriptEngine e;
QObject * o = new QObject;
MyTest * t = new MyTest (o);
t->setObjectName ("mytest");
QObject * c = new QObject (t);
c->setObjectName ("child1");
e.globalObject ().setProperty ("Form", e.newQObject (o));
e.evaluate(
"function init () {"
" print (\"init called\");\n"
" try {\n"
" var child = Form.findChild(\"mytest\");\n"
" print (\"child: \" + child);\n"
" var children = child.findObjects (\"QObject\");\n"
" print (\"children: \" + children);\n"
" } catch (error) {\n"
" print (\"Error: \" + error);\n"
" }\n"
" print (\"init done\");\n"
"}\n");
QScriptValue scriptValue = QScriptValue (e.globalObject ().property
("init")).call ();
}
