PreparedStatement Can't set value at index 1 null

Question

I've never had this situation before, but I am unable to set a value at the first position of the PreparedStatement.
System.out.println("The value = " + this.valueId);  // Prints -- The value = 479
statement.setInt(1, valueId);
statement.setInt(2, valueId);
System.out.println(statement.toString());
// Prints - "INSERT INTO table SET value = null, value_two = 479"wtf? Why am I losing the value at the first index.. Note that I am using prepared statements without error in other places of my program and I am able to set the first index with the proper value. But this, I'm stumped. I don't know how to debug this. If anyone could shed some light, let me know under what circumstances I might not be able to set a value to the first index of a prepared statement.. I'd be grateful. Thanks.

Thank you for your response. Yes that was myoversight when I posted. Indeed I have tried it both
ways, with and without the "this" in the System print
and the set statement. Currently my code appears as
System.out.println("The value = " + this.valueId);
statement.setInt(1, this.valueId);
statement.setInt(2, this.valueId);Thanks again.
is the parameter the wrong type?
if possible can you call getParameterMetaData();
ParameterMetaData pmd = statement.getParameterMetaData();
for(int i=1;i<=pmd.getParameterCount();i++){
  System.out.println("Meta Data for Parameter "+i);
  System.out.println("Parameter Type Name "+pmd.getParameterTypeName(i));
  System.out.println("Parameter SQL TYPE "+pmd.getParameterType(i));
   This should return the same for both. Otherwise we have a problem.
