solve( sin(x)= 0, x) ;
[enter] returns
{n_0*π} // ok

(Ans[1]|(n_0 = 1)) not evaluated, Why?

This may be due to the priority of the | (where) operator. The (literal) expression "Ans[1]" does not contain any references to n_0 so that substitution does nothing. After evaluation of Ans[1], you get the unevaluated result because the evaluation of n_0 = 1 happened before the evaluation of Ans[1].

There was an old thread discussing this a while back...
