I recently created a mobile application using gwt with the MVP pattern along
with a valueChangeHandler that invokes the onValueChange method when the
History Token changes. There are 3 ways that my application updates the
history token.
1) Defining the token within the html like in the following example: <a
href="#newToken">link</a>
2) Creating a clickHandler that generates an new token:
addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
History.newItem("newToken");
}
});
3) Creating a clickHandler that directs to the previous token
addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
History.back();
}
});
The problem I am having is that when a user clicks a link within mobile
safari which opens the iphone mail client (ie, <a href="mailto:
usern...@gmail.com"></a>), then returns to the application by either sending
the email or clicking cancel, then the back button within my application
(ie, History.back() ) no longer invokes the onValueChange method.
Interestingly, the history token appended to the end of the url does update
when the 'back' button is clicked, and both options 1 and 2 above still
invoke the onValueChangeMethod. Has anyone dealt with a similar issue or
could someone explain why Safari Mobile seemingly ignores the History state
after returning from the mail client?
Thanks
Daniel
