Re: [qooxdoo-devel] Refreshing mobile NavigationPage's content?
The initialize method is only called once when Page appears first time on
screen, and never again, because of a logic inside the abstract page.
Extract the page creation inside a separate method and call it on
initialize(). Also call the method when page "start" event occurs.
Then keep the "removeAll()" part, on the first line of your createPage()
method.
Then everything should work as you expected.

Re: [qooxdoo-devel] Refreshing mobile NavigationPage's content?
Hello once again :)
Is there a way to completely remove page's content? My page is a step of
some survey and after finishing it there's a possibility for the user to go
back to the step 1. Not only all the previous selections must be dropped,
but I also need to recreate the page's content completely. It's _initialize
method contains all the code for generating different controls according on
some previous selections, so I can't just drop the selections, I need to
rerun this code to generate another set of controls and to clear the
previous one. I have an event on the end of the survey on which I can run
the method to recreate the page. If I simply run the page's _initialize
method again I have the new content added to the old one. So I tried adding
a single string to the _initialize right after the this.base(arguments);
string:
_initialize: function() {
this.base(arguments);
this.getContent().removeAll();
Anyway, I'm still getting the new content just added to the previous one
without clearing it. Any thoughts?
Thanks!

Re: [qooxdoo-devel] Refreshing mobile NavigationPage's content?
Thanks for the response, but triggering the update wasn't the real problem :)
I just thought that it's impossible to change the widget which is already
added to the page's content, but I already had an event to update the page -
an "apply" event of it's property which is updated every time before I go to
this page. So to update the embed html with the property I just had to do
smth like this:
members: {
__html: null,
_initialize: function () {
this.base(arguments);
var html = this.__html = new qx.ui.mobile.embed.Html();
html.setHtml(this._genHtml());
this.getContent().add(html);
},
_genHtml: function() {
var string = "some html";
return string;
},
_reinitializePage: function () {
this.__html.setHtml(this._genHtml());
}
}
where "reinitializePage" is a method called by "apply" event of the property
from this page so by rewriting the _genHtml method I can update the page as
I want.

Re: [qooxdoo-devel] Refreshing mobile NavigationPage's content?
Hi,
I would refactor everything you do inside the initialize method inside another
method.
For example myInit : function() {
}
then I would add a listener to the page "start" event. This event is executes
everytime the page gets visible.
page.addListener("start",this.myInit,this);
Please make sure to dispose all elements you want to re-create, before.
Overwise you would get memory leaks after multiple starts of the page.
