6. Summary

The project I'm working on uses this component inside a React Portal, portals can be created inside the same document, but there are ways to create portals in new browser windows.

I have detected that the piece of code that is causing this issue is this one, and looks like:

onPaste(event){
    if (this.props.viewOnly) {
        this.stopEvent(event);
    } else {
        event.preventDefault();
        var text = event.clipboardData.getData('text/plain');
        document.execCommand('insertText', false, text);
    }
    this.update();
}

The problem is that the document is refering to is no longer the document when the component is placed, that's why it does not do anything at all.

I have modified my local library and it's working fine with this code:

onPaste(event){
    if (this.props.viewOnly) {
        this.stopEvent(event);
    }
     this.update();
}
