Nested !ifdef bug

Question

Hello,

The following sample is not working correctly:

@startuml
'No define: OK
'FILE_FORMAT_SVG: error
'FILE_FORMAT_PNG: OK
!define FILE_FORMAT_SVG 1
'!define FILE_FORMAT_PNG 1

!ifdef FILE_FORMAT_SVG
title Test SVG
!else
!ifdef FILE_FORMAT_PNG 
title Test PNG
!else 
title Test with unknown type
!endif
Bob -> Alice : hello

There is a missing !endif in your example.

@startuml

!define FILE_FORMAT_SVG 1

!ifdef FILE_FORMAT_SVG
title Test SVG
!else
!ifdef FILE_FORMAT_PNG
title Test PNG
!else
title Test with unknown type
!endif
!endif
Bob -> Alice : hello

But I agree that this is a bug and that the server should not return an error 500 in that case. We're going to investigate this one...
