Hi Sachin

What appears to be the sole cause of this error is your versions not matching up between your Flex/AIR SDK and the AIR application descriptor file. This can happen after you update/reinstall Flash Builder, or the SDK folder manually.

Just open your AIR descriptor file(generally the only XML file in the project src folder) and change the xmlns to the current version of the SDK you are using(1.5.3 => 2.0 for instance). 

and one more reason for this type of issue is that i guess some of your external dependencies like swc file are not matching with current flex sdk version

let me know if this works for you...

Hi Sachin,

Transition from 3.6 to 4.6 is not very complex nor its too easy what I mean to say is that there are somethings that you need to consider while you are moving to higher end versions of Flex SDK.

1. Flex 4 supports a spark skinning architecture which may sound complex for anyone new to it , if you are largely depending upon css based development/tweaking of your custom or native flex components then you it may not help you alot though you can use css also but there are some components in flex where css rules may not apply like Group/VGroup/HGroup as in skinning where you have the full liberty to change the full UI of the built-in components under Adobe's terms and conditions at the same time you may find it quite complex in maintaining your skins if you have no prior knowledge of skinning so I should recommend you that you should get some knowledge on it first.

You might need to change or configure your themes accordingly like Halo , Spark etc etc.

2.Regarding your service layer things may remain the same as they are currently with your current SDK version you may have to change one or two things but nothing very much is required at this end.

3. Data model will also not get much effected in transition but you will need to be careful while using advance data components of Flex like Advanced Data Grid OLAP datagrid.

4. Good support with backward compatibility and earlier versions of flex. Flex 4 supports full backward compatibility of your components you may only need to change the Application tag of your project according new Flex 4 based and rest is good to go.

5. Localization- this would almost remain same no special things required.

Note: These were a few things that I considered or encountered in my experience while I was taking my product to higher level SDK in flex but these are not all the things you may need to do some more Google on it. As these are some things that are normally considered on first priority in transition phase but remember they are not the all.

You can further read these 2 very informative and good articles

Hi Anas, Now in application autocomplete combo box displaying text from right to left, if I type some text to search like ABC it shows like CBA, As I changed setSelection to selectRange , and anchor position as per flex 4 upgrade. But auto complete combobox is not working properly, Please help if you have experienced the same.

Hi Guys,


I am facing issue with auto complete feature where I have replaced  textInput.setSelection with textInput.selectRange and textInput.selectionBeginIndex with textInput.selectionAnchorPosition as per flex upgrade standard but it started strange behavior for combobox in application. At runtime when I type text leike "ABC" into combobox it always move cursor in the leftmost position and type in reverse order like "CBA". 

Please provide some help if anyone experienced with the same issue or point me any solution. It would be a great help.

Regards
--Sachin
