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!
    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


> "Cannot pop while operation is in progress" means that the previous
> PageStack operation is still animating, and you must wait until it
> finishes before issuing the next PageStack operation.  There are various
> strategies you can use for this, but they will all result in unattractive
> visual changes: either double animations or disorientating jumps.
> It sounds like you should probably use the 'replaceAbove' function:

> This function is equivalent to "pop all pages above the supplied target
> page, then push a new page", except that it occurs with a single visual
> transition.
