- Oct 24, 2013Never tried right clicking on the framework files before. You're right that it doesn't work. But double-clicking should set a breakpoint. It does for me.From: Tom McNeer <tmcneer@...>

Subject: Re: [flexcoders] Nested TabNabvigator/Repeater errorThe framework is being merged into the code at compile time.I am now trying to follow the event down into the framework. But I'm running into what seems like a dumb problem: I am unable to set breakpoints in the framework files. I can search for and open class files in the correct version of the framework; but a right-click in the left margin does not bring up a context menu at all.I realize that the proper course would be to follow the event into the framework files. However, in my initial post, I was hoping that someone might have experienced a similar problem and know a simple solution.Alex,I was responding to your comment about the concern being the logic that responds to the change in the TabNavigator and TabBar. And I simply meant that my code does not contain any handlers for any actions on the TabNavigators created in my AS code, nor on the underlying TabBars. But rather, the click on the visible Tab that _appears_ to be responsible for switching the ViewStack is being handled somehow by the framework, since I have not overridden it.
Thanks again for your reply. Sorry I was unclear. I wasn't suggesting that the framework had code to switch the ViewStack on click.
I know this may be a silly question, but can you tell me why Flash Builder (4.6) might be acting this way?On Wed, Oct 23, 2013 at 2:40 AM, Alex Harui <aharui@...> wrote:I'm not sure what you mean by "the framework".

The reason I used the vague "switch to a different screen" is that the resulting action is nothing that is called in the component or even its parent.I'll lay this out as quickly as I can:There's a view we'll call Cases which has a ViewStack that consists of "Case Results" and "Case Details." A search triggered from a parent of the Cases view results in a grid in Case Results being populated. A click on a row in the grid calls the server for data on an individual Case and switches to the Case Details view.
That view contains a TabNavigator for various aspects of the Case, including Documents. The nested TabNavigators I'm trying to create are within that Documents view.When I say that a click on any second-level (Document subtype) tab goes "to a different screen," what happens is that everything is switched back to the Case Results view - taking you back to the first element in the Cases ViewStack. There's no action or event defined in any of the child views inside the Case Details TabNavigator that would switch the view that way.That's why I find it confounding.If you put a breakpoint on code that does that, does it get hit and will the stack info show you how it got there?The code would be in the framework. It would just be the handler for a click on the TabBar.
The TabBar children should just be Tabs that dispatch events. The logic that responds to the change event should be the main concern.Thanks. I understand that. But I'm not writing any code to react to the click event. It's just the default action from the framework, which should be to make the box corresponding to the Tab the selectedChild of the TabNaviagator.I have tried walking through my ActionScript, and the oddity I see (which I may not really understand) is that even after all the custom components are added as children to one of the second-level TabNavigators, the TabNavigator and its TabBar show in debugging as having a different number of children.
