[SailfishDevel] Cannot pop while operation is in progress

[Wim de Vries]

Thanks Matt,
This is my function in main.qml (called from within c++)
  function loadTextEdit(text)
    {
    //pageStack.push(Qt.resolvedUrl("controls/MTextEdit.qml"))//works OK!
    pageStack.replaceAbove(pageStack.currentPage,
Qt.resolvedUrl("controls/MTextEdit.qml"))
    pageStack.currentPage.setText(text)
    return true;
    }
this results in this error:
file:///usr/lib/qt5/qml/Sailfish/Silica/PageStack.js:111: Error: Cannot
replace with target page at the top of the stack
