QTP does not recognise elements randomly

[Pkapoor]

Hello ,

I have following code which i have created using record and play and minor tweaking :

Code:

JavaWindow("StorageManagement").JavaDialog("Add").JavaEdit("JTextArea").Set(fData)
If  JavaWindow("StorageManagement").JavaDialog("Add").JavaButton("OK").Exist(2000)
Then
JavaWindow("StorageManagement").JavaDialog("Add").JavaButton("OK").Click
Else
Reporter.ReportEvent micFail, "Add_Appliance " , "OK button is not visible/appliance can not be added"
ExitTest
End if
' Verify if appliance was added
If JavaWindow("StorageManagement").JavaDialog("JDialog").Exist(30) then
    Reporter.ReportEvent micPass, "Add_Appliance " , "Appliance can not be added"
    ExitTest
       End if

In this code my QTP code randomly stops recognizing elements in lines like:

Code:

JavaWindow("StorageManagement").JavaDialog("JDialog").Exist(30)
OR
JavaWindow("StorageManagement").JavaDialog("Add").JavaButton("OK").Exist(2000)
OR
JavaWindow("StorageManagement").JavaDialog("Add").JavaEdit("JTextArea").Set(fData)

Does this have something to do with Object Repository or some setting?
Some times it fails, sometimes it pass , sometimes when i click on retry the step .. it goes ahead and pass.

Plz advice , I am amused at this point in QTP

As mentioned at the top, please ensure to put all your codes in code tags.

To me this looks like a sync issue rather than object identification issue.

How can i get rid of this issue ?
What can be done to make this test case pass everytime?
