Multiple dialogs displayed after clicking the confirm button not working

[adrianamendoza]

I need to display more than one confirm popup using an special order, like first popup "A", then "B", and then "C", each one of them must have a confirm button so the next popup will be opened when it is pressed.
I tried with "simpledialog" popup but I got all the three popups overlapped, so at the end I only had the last popup.
I also tried with "simpledialog2" but I had the error "Uncaught TypeError: Cannot read the property 'sdIntContent' of undefined."
Is there a way to open a popup only if there is no open popup?
