[SailfishDevel] Cannot pop while operation is in progress

[Wim de Vries]

I also tried
pageStack.replaceAbove(Qt.resolvedUrl("controls/MTextEdit.qml"))
which should remove the current page, but then:

file:///usr/lib/qt5/qml/Sailfish/Silica/PageStack.js:111: Error: Cannot
replace with invalid target page which is not present on the stack


> 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
