QTP 10 as of now does not display code hinting for flex operations and this can be a real problems for users that work extensively with decriptive programming.
We are currently working with QTP to get this sorted out but till then here is a workaround which you can use.
1.Copy the TeaFlex.xml from Flex folder present inside the Flex plugin for QTP folder and the TeaFlex_AIR.xml from the AIR foder also present inside the same Plugin folder.
2.Place these xml files under the C:\Program Files\HP\QuickTest Professional\dat\Extensibility\TEA folder within the QTP10 installation.
3.Then type regedit in the command prompt and open the registry.
4.Then you need to add string value “C:\Program Files\HP\QuickTest Professional\dat\Extensibility\TEA” to HKEY_CURRENT_USER\Software\Mercury Interactive\QuickTest Professional\MicTest\StepInformationManager\TypeInfoFiles node in the registry.
5.Once you do this restart QTP and you will notice that the code hinting appears 🙂
