This seems to be a newly introduced issue on Polymer 1.0+, wherein the paper-icon-item element is receiving focus when tabbing through the page. In the past, if the paper-icon-item contained a paper-input, the paper-input would would receive the focus, not the paper-icon-item container. Has anyone else noticed this issue, and perhaps have a resolution?

As anyone can notice it, in the schedule external drag drop demo , someone can drag the event from the TreeView list and when it get near to the right page edge then the page scrolls to the right.
Here is a screenshot showing it.
It's occuring also in our app and it's rather annoying.
We wish there will be a fix for this issue.
Greetings from Syncfusion Support.
We have checked your reported problem that dragging a TreeView node that produces the scroller in the output web page. Currently, we don’t have any property to prevent the scroll when dragging a TreeView node. However, we have already considered this as a feature from our end. It will be included in our Volume 2 Release which is expected to be released in June 2020.
Track the below link to know the feature status.

But, you can resolve your issue by setting the target for dragArea of TreeView’s drag object in the created event. When setting the target, you can drag the element only inside the target element. It prevents the element from scrolling exceeding that element.
Please, check out the sample with the above explained solution.

onCreate(){
this.treeObj.dragObj.dragArea = "body";
}
I've added ScaleImageLabel to swipe Tabs. I want to calculate amount of time each tab remains in focus. I added focus listener to Tabs/ScaleImageLabel but it's not getting fired. It's working when added to the form. Any suggestions on how to achieve it?
If I understand correctly what you need is a tab selection listener. Focus listener will only work for focusable components and labels are by default non-focusable. I would recommend avoiding it since focus is used for key based navigation. It might produce different results than you would expect.
I have a problem with Office UI Fabric's Panel (well, also Modal). I'm rendering them with multiple input fields to provide data for my app. Due to the number of fields the controls are rendered with a scroll bar. After scrolling down and clicking outside of the input, the focus is being set on the first textfield/dropdown in the container panel what causes the whole thing to be scrolled to the top. Is there a way to prevent setting the focus/scrolling to the first element when clicking outside of the input?
This was indeed a bug and has been resolved already. Tested it in the version 5.56.0.
I'm displaying a Popup in response to a button click (popup.IsOpen = true;). The popup contains a ComboBox, and when I click an item in the combobox, one of the things the SelectionChanged event does is to hide the popup.
The Popup appears over a DataGrid that I also have on my page, and I'm finding that the mouse-click on the combobox is also being picked up by a MouseUp event that I've got on the DataGrid. Any idea what's going on?
The MouseUp Event has a routing strategy of type Bubbling. Events that use this type of strategy get passed up the chain to parent controls. Since the Popup is a child of the DataGrid, the event will "bubble" up to the DataGrid. If you would rather the event not bubble, you can try using PreviewMouseUp, which has a Tunneling routing strategy, and will "tunnel" down the chain to child controls. Here is a decent overview of Routing Strategies.
I've hit the same issue. Oddly, it doesn't happen when the code is run in the debugger - it only happens in the release version. It really seems to be a bug in WPF. Trying to catch the click and set the event to handled doesn't work.
My workaround is to, when the popup opens, to tell the control underneath to ignore the click.
I am trying to build an app using Extjs 4.1. In general: it is a viewport with a tree panel on the west and a center panel that it is actually a tab-holder panel. When a user clicks on a tree node a tab is populating the center view. I had set an attribute in the tree panel that after selecting a node it gets deselected (deselectAll). The reason for this is that the user can open many tabs from different places (e.g. within each tab). But, when I set the above attribute it is producing an error (the “data” is undefined). The data that is undefined is the data related to the tree node. So, the question concerning selection model:
How can I address this problem (a solution may be to select the fist node, but I don’t want it)?
As for the history utility, I need to implement browser back button. Especially I want to disable browser’s refresh button. If user opens let’s say 15 tabs and accidentally click on browser refresh or “F5” he/she will lose everything. I had tried many things but with no luck. I am unable to understand “Ext history util”. So,
Is there any good example out there?
Could anybody guide me on how to do it?
Notice that the application is built respecting the new “MVC” architecture.
Stopping the refresh event is pretty easy - providing that your page has the focus. E.g.:
Ext.getDoc().on('keypress', function(event) {
if (event.getCharCode() == event.F5) {
event.stopEvent();
console.log('you stopped the refresh event');
}
});
If your page doesn't have the focus then there is nothing that can be done -- but most of the time your page loses the focus when a different browser tab is opened so F5 would be refreshing that one instead anyway.
I'm still trying to wrap my wits around the first part of your question, but I thought I would share that.
EDIT
Instead of trying to stop the default browser behavior (something which you can only do on a very limited basis), you should look into state management. ExtJS supports it on many components. Here is the ExtJS example.
Also here is the example of controlling browser history.
