Ipage setProperty() method problem in upgrading from tapestry 4.0.1 to 4.1.6

[Sai Kiran]

I am trying to upgrade from tapestry 4.0.1 to tapestry 4.1.6. In tapestry
4.0.1, for object Ipage we had a function setProperty(String, Throwable)
but it does not exist in Ipage object in tapestry 4.1.6. Please let me know
whether the function is deprecated or do we have any alternate function to
use.
