Bugfix
TL script function log() is implemented by the class com.top_logic.model.search.expr.Log.
It inherits the implementation of the method isSideEffectFree() with return true; from the super class GenericMethod.
This is incorrect as it has a side effect (writing to the log). This method should therefore be overwritten with return false; (analogous to the com.top_logic.model.search.expr.Info class).
Test
