Getting problem while playback QTP scripts

While play backing the qtp scripts on java application i am facing the different kind of problem.

The data is not getting entered into the cells of a particular table which is in application.

Ex: JavaWindow("Organization Editor").JavaTable("Record 1 of 1").DoubleClickCell"#1","Note","LEFT"
Set Wshshell=createobject("wscript.shell")
Wshshell.sendkeys "test"

as in the above script the value "test" should get entered into row 1 of column "Name"

But while play backing the script the particular row gets activated by the data does not get entered.

and while play backing the application environment also gets changed. The cell gets turned read only..

Is this a Application Problem?
Why this may be happening?

Please reply soon.. need your help

thanks
