Hai to every one.
i have one Search node it contain attribute .
i made one action button under that written code
by this see all attribute become invalidate.
but i want one attribute should not invalidate in case i press button action.
how to write the code.
once you invalidates the node all attribute values with in that node clears.
if you want to restore value of a attribute in this case maintain dummy attribute outside of node you invalidating.
