Description

Hallo Katja,

Beim Öffnen einer In-Referenz einer Referenz, die selber bereits im Dialog geöffnet ist, kam reproduzierbar folgender Fehler.
Kannst du mal sehen, ob offensichtlich ist, woran das liegen kann. Beide Referenzen sind preliminary.

Leider ist DB derzeit noch lokal nur bei mir.

Wie es mir scheint, liegt es aber daran, dass colors nicht gesetzt ist an dieser Stelle. Wie kann man sicherstellen, dass colors immer einen Wert hat?
form.setBackground(colors.getBackground());

Viele Grüße,
Andreas M.
