[mania]

Hi,

I have wrote BR for When time worked field is restricted like "before ticket is updating please fill the time worked field" to restricted to all the fields except assignment group and assigned to fields on Problem form.

But here I used the same code on Incident form Its working fine but in Problem form when I update the time worked fied and click on the 'Fix' button its showing again this error and Except When I click on 'Fix' and 'Accept Risk' button It is asking again that error.

Can anyone suggest me why because of this is happing. It will be helpful.

Thanks in Advance!
