From Titan v15 on ClearAll() requires two parameters, see Programmer.Editor.ClearAll.
Simply change the relevant line(s) to Programmer.Editor.ClearAll(false, false).

• Programmer.Editor.ClearAll
• Group.RecallGroupNumeric
• Palette.ApplyPalette
• ActionScript.SetProperty
• Palette.StoreCurrentPaletteReplace

• Palette.CurrentPaletteHandle

 <step>Programmer.Editor.ClearAll()</step>
 <step>Group.RecallGroupNumeric(101)</step>
 <step>Palette.ApplyPalette("paletteHandleUN=100", false)</step>
 <step>Group.RecallGroupNumeric(102)</step>
 <step>Palette.ApplyPalette("paletteHandleUN=100", false)</step>
 <step>Group.RecallGroupNumeric(103)</step>
 <step>Palette.ApplyPalette("paletteHandleUN=101", false)</step>
 <step>ActionScript.SetProperty("Palette.CurrentPaletteHandle", handle:"paletteHandleUN=113")</step>
 <step>Palette.StoreCurrentPaletteReplace()</step>
 <step>Programmer.Editor.ClearAll()</step>

This explains the functional steps within the sequence. For all the other XML details please refer to Formats and syntax

• Programmer.Editor.ClearAll ensure the editor is empty
• one by one various groups are called and a palette is applied:
  • Group.RecallGroupNumeric selects a group
  • Palette.ApplyPalette applies a palette to the fixtures in this group
• ActionScript.SetProperty(“Palette.CurrentPaletteHandle”, handle:…) selects the palette where the result is to be stored
• Palette.StoreCurrentPaletteReplace stores/replaces the target palette
• a final Programmer.Editor.ClearAll clears the editor again

Note that the target palette needs to be recorded as normal palette in the first place else this would store only the last colour information as shared or global.
