similar question has been asked before SEE HERE
basically i get a Another exception was thrown: ScrollController attached to multiple scroll views.
because i have multiple scrolls with the same controller.
how do i use it properly then?
the documentation literally said "scroll views that share a single TrackingScrollController."

Vaadin is mostly based on individual interactions such as clicking buttons or scrolling in a grid, rather than viewing pages. What you can still do is to use UI::addBeforeEnterListener to get an event before navigating to a new target. You can use a VaadinServiceInitListener to register that listener for all your UI instances.
For more information, have a look at this blog post that I've written on the topic.
I'm trying to build a view in laravel that will allow the user to drag and drop widget on and off the page as well as around the page and resizing them.
Everything I read suggests this is not possible in laravel as the view seems fairly immutable.
Does anyone have any pointers?
ok.. no laravel can't do it, at least thats what I think..
However you can do it with javascript and store the widget locations in laravel..
Things I did find though for the next person...

I have an application with an accordion. The accordion's section .content is pulled from a server, generated dynamically and can be rather large. Therefore it would be best to load the content only when the user opens the section. My though is that the best way to do this would be binding to a section open event, display a loading icon while fetching the content, then displaying that content.
However, I'm having great difficulty binding to the open event. There does not seem to be a great deal of documentation on the new Foundation 4 section/tabs/accordion. What I did see may have been for foundation 3. It said open/opened/close/closed events should be sent, but they do not seem to be thrown.
The only event I seem able to bind to is "click." Which would work, except the accordion frequently loads with the first section already open. I could run myExampleDynamicLoader($('section.active')) on document ready, but it seems like there should be a less hackish way.
I created a jsFiddle to show what I'm talking about http://jsfiddle.net/HurricaneJamesEsq/6sGGD/14/
Any suggestions?
After reading through the foundation.section.js source, it is pretty clear that sections do not trigger any events. A pull request was added, but in the mean time it looks like this can only be done via 'click' events.
TL:DR - How do I create Relationship Segues in Xcode 4.4?
Hello everyone, I have an app where I want to add some tabbing behaviour to one of my controllers but, due to design decisions, I can't use UITabbar. I already know about using a UIToolbar with a UISegmented control inside it, but where I'm having difficulty, is how to switch between view controllers.
I know I can't use normal segues (since each tab change would keep stacking a new controller on top of the previous), but UITabBar has something called "Relationship Segues". I looked around but couldn't figure out how to create one.
Does anyone know how do it? Also, is there a better way to approach this problem?
Thanks
I've done the exact same thing recently. I've created a container view controller, SegmentedViewController, and added the view controllers I wanted to switch between to my container controller using addChildViewController. Upon switching view controller (I used target/action on my UISegmentedControl), you call transitionFromViewController:toViewController:duration:options:animation:completion. That's the general idea. Look at the "Implementing a Container View Controller" section here for implementation details.
I have a Conductor<MyItem>.Collection.OneActive ViewModel and try to attach the application bar buttons to methods of MyItem with cal:Action.TargetWithoutContext="{ Binding ActiveItem }". My view is a Pivot, if someone wonders why am I trying to attach the application bar to a child ViewModel. The compiler says "Property 'TargetWithoutContext' is not attachable to elements of type 'AppBarButton'." Though it works with normal buttons elsewhere in the view.
How can I get it work? Or maybe any workaround?
The AppBar functionality that Caliburn.Micro provides is a hack due to the flaws in the underlying framework, which doesn't allow arbitrary binding. Unfortunately, we can't support TargetWithoutContext. For AppBars the target will always be the page's view model and messages can only be directed to it. If the page's view model is a conductor, and you want a child to receive the message, you could have the conductor receive it and then forward it on to its ActiveItem.
Unfortunatly the ApplicationBar is not bindalbe as it is not Part of the Silverlight Framework.
You can only interact with the Application via the Code Behind File of the Page which uses the ApplicationBar.
You have to register the Click Event and invoke the Action form the code Behind.
The WP7 ApplicationBar is just a simple wrapper around the native shell and doesn't support data binding at all. However, there are a couple of workarounds available.
