I have class that the MainPage of my app can access, but it requires user input for the ip address so I've setup a new page rather like a settings page, if I add the same code as the MainPage the socket works as expected but I only want to send the connect command from the settings page then allow the MainPage to send the values to the socket... if I connect on settings page and then try to send data from MainPage I get "Socket not initialized" when it was as it was done from the Settings Page, can anybody explain whats happening here and possible solutions? it's like the app page is two different 'ecosystems' and the two can't combine methods and vars etc?
Am I looking into this wrong and yes you've guessed it I'm hopelessly new to all this!
Each page in a WP app is a separate class. So where is your Socket object declared? If you declared it as an instance variable of the MainPage class (for example), it would not be in scope when the Settings page is active (or vice versa).
To allow both pages to reference the same instance of Socket, you can declare it as a public member in App class. And you'll probably want to declare it static as is done with App.RootFrame in the automagically generated app templates, to make it easy to reference.

I'm writing a Flutter web application and I want to write a test on the behavior when the user loads the app when he types the URL in the browser's address bar.
For example I would like my test to behave as if the user typed /my/path.
How can I do that?
If you look at the class PlatformDispatcher (which olds a singleton instance .instance) you can see a getter defaultRouteName.
The route or path that the embedder requested when the application was launched.
This will be the string "/" if no particular route was requested.
So when your user starts your application with the url /my/path, PlatformDispatcher.instance.defaultRouteName with be equal to '/my/path'.
How to mock it?
You can also access the PlatformDispatcher.instance from WidgetsBinding.instance.platformDispatcher and if you read the doc of the getter platformDispatcher, you'll read:
A subclass of BindingBase, such as TestWidgetsFlutterBinding, can override this accessor to return a different ui.PlatformDispatcher implementation.
In the context of a testWidgets
testWidgets('', (WidgetTester test) async {});
tester.binding gives you access to the TestWidgetsFlutterBinding which is the binding used by widgets library tests. In this test binding, the platformDispatcher is overridden and a TestPlatformDispatcher with a setter defaultRouterNameTestValue that you can use to mock the defaultRouteName getter.
TL;DR
You can use:
tester.binding.platformDispatcher.defaultRouteNameTestValue = '/my/path'
to test the behavior when the user loads the app when he types the URL /my/path in the browser's address bar.
On creation of new external user from ATG BCC, I need to include some logic like encrypting password and sending email to user. Achieved this functionality by extending GSAPropertyDescriptor class and overriding its getPropertyValue(RepositoryItemImpl pItem, Object pValue) method.
Problem is, this method is getting called only when we click on create button from "General" tab present in users section, but not on click of same create button from other tabs like "Commerce", "Orgs & Roles", "User Segments" and "Advanced".
Please suggest!!
It is not a good idea to override getPropertyValue of an item for this implementation. The right way to do this is to work with the formhandler that is responsible for saving the user. It is a bit tricky to find this formhandler. It will be in the atg/web/viewmapping/ViewMappingRepository/ of the BCC instance. In this repository there will be lots of formhandlers configured for different purposes. You have to pick the one relevant for the user edit. Here is an example of what you might find there:
With this, you go to appropriate Formhanlder, like /atg/web/assetmanager/editor/profile/UserFormHandler mentioned here. And override that component in your module with your own implementation. Once that is done, you'll have the control of the action. You can do your work and pass on the control to super class (the original implementation).

I'm developing my first Facebook app using custom Open Graph actions and objects, and I'm trying to avoid needing to deploy after each code-change (in this case, to my automatically setup heroku-account).
The problem started while I was getting set up to test the publishing of my first custom action. I was trying to set up everything in terms of the dev-version of my facebook-app, except for my "object" page, which, as I understand it, needs to be publicly accessible (to scrape the OG meta-tags).
I made a test-page for my custom object, copied the auto-generated set of OG meta-tags into it (citing the dev-version of my app_id, but with the public URL of the prod-version of my app for og:url) Then, I used the facebook "lint" tool on that test-page, and it, I guess not surprisingly, complained about that public domain being invalid for the relevant app (the dev-version of my facebook app).
Object Base Domain Not Allowed: Object at URL
'http://foo.herokuapp.com/testEventPage.php' of type 'foo:product' is
invalid because the domain 'foo.herokuapp.com' is not allowed
for the specified application id '(the app_id)'.
Then, I learned about using Tunnlr to port-forward from a public site to my local env and proceeded to get that set up.
I'm using MAMP with a virtual host config as follows:
<VirtualHost *:8888>
DocumentRoot "(the relevant docroot)"
ServerName foo.local
SetEnv FACEBOOK_APP_ID (my dev FB app-id)
SetEnv FACEBOOK_SECRET (my dev FB secret)
</VirtualHost>
And I'm using tunnlr, with the cmdln for it pointing to port 8888.
Using the public URL provided by Tunnlr, I am successful in accessing my local pages, but, when I try to use the "Login" button on the page that came with the example PHP-code from Facebook, the login-dialog pops up but immediately disappears, though when accessing it directly locally it works fine.
Could this be cookie-related? Something to do with port-forwarding and cookies?
Is there a better way to develop Facebook apps, in particular ones involving custom Open Graph actions and objects?
EDIT: like the doctor said, if it hurts when you move your arm like that, don't move your arm like that! In other words, access the Tunnlr-URL via the Facebook-Canvas URL, which POSTs the embedding page's current login to your own page; and, as a user (optionally a test-user), don't use the example-code's login-button; instead use the embedding page's login-feature. So, I've answered my own question.
I'm wondering if you could suggest me any way to implement "user roles" in GWT applications. I would like to implement a GWT application where users log in and are assigned "roles". Based on their role, they would be able to see and use different application areas.
Here are two possible solution I thought:
1) A possible solution could be to make an RPC call to the server during onModuleLoad. This RPC call would generate the necessary Widgets and/or place them on a panel and then return this panel to the client end.
2) Another possible solution could be to make an RPC call on login retrieving from server users roles and inspecting them to see what the user can do.
What do you think about?
Thank you very much in advance for your help!
Another way is to host your GWT app in a JSP page. Your JSP might contain a snippet of code like this
<script type="text/javascript">
var role = unescape("${role}");
</script>
Where ${role} is expression language expanded from value you computed from the associated servlet / controller and exposed to the JSP.
When your GWT app runs in the browser, the value will be filled out. Your GWT app can easily call out into JS to obtain this value from a native method call, e.g.
public native String getRole() { /*-{ return $wnd.role; }-*/;
So your module could invoke getRole(), test the value and do what it likes to hide / show elements.
Obviously your backend should also enforce the role (e.g. by storing it in the session and testing it where appropriate) since someone could run the page through a JS debugger, setting breakpoint or similar that modifies the value before it is evaluated allowing them to access things they shouldn't be accessing.
Following scenario works for me:
GWT app is behind security constraint.
On module load I make RPC call to retrieve roles from the container. I store them in main GWT module's class as static field, to make it easy for other classes to use it.
Each widget (especially menu) can use roles (e.g. call Main.getRoles()) and construct itself according to roles. I don't pass roles in constructor. Each widget knows how to behave depending on role.
If it's crucial to not only hide things but also enforce them you can use container security and check roles and rights while invoking business methods.
While using GIN you can also create singleton class to store roles retrieved during login and inject it wherever you need it.
Problem:
I have a webforms app where every page inherits from BasePage.cs
I also have another class AuthenticatedBasePage.cs which inherits from BasePage.cs
BasePage.cs has some code which finds out if a Forms Authentication cookie is set, and if so, sets a IsAuthenticated boolean flag and a MyAppUser object (only has properties such as name, age, gendery) which means every page on the site can see if the user viewing the page is logged in or not, and if so, read the values of MyAppUser.
AuthenticatedBasePage has an additional feature where if anyone tries to browse to a page inheriting from this class are not authenticated, they are redirected to the login page with a 'returnurl' querystring variable set.
I would to have a similar setup in my MVC2 app. I've done a fair bit of reading that says I shouldn't reference HttpContext in my BaseController.cs (which all my controllers inherit from) as that means I can't unit test it. My first question is, how can I make the IsAuthenticated and MyAppUser objects available to every page? Secondly, how do I create pages which only authenticated users can access, and if they are not authenticated, they get redirected to the login page with the returnurl querystring variable set?
Many thanks,
A.
P.S. I'm not using the MembershipSchema, I'm only using the FormsAuthentication.SetCookie method.
What you want is the Authorize attribute. This article has a great explanation of how to use it with forms authentication.
