Description

Problem

service Foobar {
  void Test( 1: i32 someValue = 42)
}

The default of 42 is set into the Test_Args structure in most languages, but later overwritten because the generated calls do completely ignore these defaults. One has always to call:

client.Test( 1);
client.Test( 42);
client.Test( 4711);

instead of

client.Test( 1);
client.Test( );  // 42 is the default
client.Test( 4711);

Applies to

Most (all?) languages.

Todo

Create a sub-task for your particular language and add the patch.
