Post your code you want get working.
Use dynamic addEventListener adding to each component, and also add this function to parent boxes too, in all cases.

I have a WKInterfaceMenu added to the storyboard which is working great. However, once used, I don't want the menu to appear for a second time.
Is there a way of preventing the menu from appearing?
You can definitely do this, but you need to do things a bit differently.
First off, don't set up the context menu in the storyboard. Instead, set up all the menu items programmatically. You can add and remove menu items using the addMenuItemWithImageNamed and clearAllMenuItems methods on your WKInterfaceController instance.
You want to set up all your menu items initially, then remove them in all your callback methods for each menu item. That way, they'll be there at first, and will be removed once you select one of them.
I need to completely initialize a custom component in my Flex app (i.e. I should be able to access it from action script and get its properties and its children etc), But I do not want to add it to the display or make it visible.
I have tried to add it to my visible component, but keep it visible, but often many of its properties are set only when it is drawn, so i don't get what i need.
Is there a way to add a custom component to some sort of 'Virtual' display, that is not visible to the user?
You could add the component to an invisible Sprite - that way the component itself could both be on the stage and have its own visible property set to true.
Did you try using initialize()? After a view is added to the display list, the initialization stage begins. Calling initialize() before addChild() should let you initialize the view without needing to first add it to the stage.

Not sure if possible without adding it to the display list, although I'd wish it were to some extent.
I once had to make custom drag proxy, which didn't work with the real component, because of some weird skinning issues. So instead I had PopupMananger add a box as a popup, added my component to the box, called validateNow on the component, drew it in a bitmap data, removed the popup, and used the bitmap data as the proxy.
So what you were trying was missing a call to validateNow most likely.
when user clicks on Add button, then a pop up button will be opened with certain form elements (like textinput, date field, text area).. When i used 'TAB' inside this form,it is not working. I found in couple of Questions / forums that we need to create an instance of FocusManager and then bring/activate focus for the pop up. But still i didn't see the tab working inside the form. In order to tab order working inside a pop up, what steps we need to follow.
I tried using focusmanager and property like tabfocusenabled, tabenabled and also added taborder inside each form element. But no luck.
Iam using Flash Builder 4.5 and using spark components for development.
Is there any workaround for this problem?
Thanks in Advance,

Thanks for all your responses.
Finally the issue has been solved by one of my colleague. Problem is , the form has been loaded inside Horizontal accordion (flexlib HACCORDION). So inorder to draw focus inside the accordion to child elements, we need to add 'hasFocusableChildren="true"' for the HAccordion (horizontal accordion component). Adding this property solves the tab order problem.
I have also pasted the code below:
I have created a custom item renderer for the tree, i have added some children in create children function, my problem is that sometimes i need to show these children and sometimes i don't, depending on clicking on a button which also i have added at create children, the problem is that i had to create the item even if i don't want it to be visible, and removed it by making visible false, and this costs a lot of memory, i have tried to create it at buttons click listener but when scrolling the child disappears, and it may appear again if i keep scrolling up and down..
i am trying to add the child just when i need it to be visible, is this possible or i have to create it on child creation method?
Typically you do something like this with states. This way the components within the container (in this case your item renderer) are only created when the container enters the given state. The nice thing about taking this approach is that you can remain oblivious to when components need to be created/removed and let the states model handle that for you. Hope that helps.
In my flex app I have custom tooltips on buttons that hide and show based on user context.
The problem that I dealing with is that when I call my showTips() function I only want to show tooltips on the buttons that visible in the view. So buttons that on a un-selected tab (tabNavigator) should not show the tooltips.
For some reason all tooltips are showing.
Is there a way to detect if a button is not in current view, like on a un-selected tab?
If you gave us some code I could check this out, but would this work?
if(button.parent.visible) { showTip(button);}
Instead of custom coding for each button, make use your tabnavigator's creation policy is set to "auto".
