[flexcoders] Flex 4.1 scrolling problem

[bu4fred]

I'm committed to using a spark container because I need to use the spark states 
model.

I would like to create my own component that would automatically scroll as 
necessary and appropriately adjust the scrollbar on a browser window resize.  
This generic scrolling container may be included in a tabnavigator or other 
containers (that should not scroll) to get the desired layout.

It look like all I need to do is wrap the spark container in a Scroller or link 
a Scroller to the container.  

My problem is that AFAIK you cannot add elements to a custom mxml component if 
you've already added a component (like a s:Group ) to the component defnition.  
I.e. I cannot use mxml to define a custome component that is an s:Group inside 
a Scroller.  So I guess the approch is to create a custom actionscript 
component.

I'm hoping somebody has already solved this problem and can point me toward a 
link or provide a snippet.

I plan to upgrade to Flex 4.5 in a few months if that's relevant.

OK, I think I've got it although I don't really know why.  The base mxml 
component and all of its children are in a package/directory called sections 
so the code needs to be in EACH child as follows:

sections:_section xmlns:fx=http://ns.adobe.com/mxml/2009; 
xmlns:s=library://ns.adobe.com/flex/spark 
xmlns:mx=library://ns.adobe.com/flex/mx
xmlns:com=components.*
xmlns:sections=sections.*
xmlns:mds=mds.*   
creationComplete=_section1_creationCompleteHandler(event)


sections:states
s:State id=Oct2010 name=Oct2010/
s:State id=Oct2011 name=Oct2011/
s:State id=Apr2012 name=Apr2012/
s:State id=Everything name=Everything/
/sections:states

FYI, I have different versions of this app that must be supported 
simultaneously and based on a few fields in the app, the actual version can 
change in mid stream.  Everything is just there to help me with initial 
debugging.

[flexcoders] Flex 3 - 4 migration and s:States

[bu4fred]

I'm migrating a flex 3.0 application to 4.0 (or 4.5, doesn't matter much) and I 
want to use the new state features of includeIn and excludeFrom.  I have a user 
defined base class in mxml and i inherit from that for my 'working' classes.  I 
have this code in my baseclass

mx:TitleWindow xmlns:fx=http://ns.adobe.com/mxml/2009; 
xmlns:s=library://ns.adobe.com/flex/spark 
xmlns:mx=library://ns.adobe.com/flex/mx
xmlns:com=components.* 
currentState=Oct2010

mx:states
s:State id=Oct2010 name=Oct2010/
s:State name=Oct2011/
s:State name=Apr2012/
/mx:states
. . .

- working class contains -
mx:FormItem  includeIn=Apr2012
... 
/mx:FormItem
 and the error is 

State 'Apr2012' was referenced without being declared.  A.mxml  line 66

I tried s:states rather than mx:states but it could not resolve name
Must s:states be used only in s: components or can they be used in mx 
components?

[flexcoders] mx:Datagrid nowto detect drop column

[bu4fred]

I would like to move cell contents around in a datagrid (or AdvancedDatagrid if 
necessar) but so far all I can do is detect the row of the drop target.

II need to get both the row and column index of the source and destination of 
the drag-n-drop action.

Any suggestions please???

FWIW  FOP from Apache's XML project group does a pretty good job of
generating PDF.  It would of course have to run strictly on the server.

I appreciate all your advice on Print bugs, I thought I was just
experiencing noobie pains.  I guess I'll just settle on displaying an
HTML page and let them print that.  

It's too bad, printing a single page is really nice in flex, but if it
goes downhill, as many have said, with multi-page grids, screw it! I
don't have the time to make it work.
