[govardan_raj]

hi Guys,

I have an application with an Price Basis Input , which is a value help.

some times i get error as shown below & value help is empty. i.e. if application is launched 10 times, then 4 to 5 times i get the below error , where i have to log off , then login again and reload the application and then the value help works.

Please help to resolve.

hi Fabrice Podevin ,

Please find the below code.

 PriceValueHelp:function()
