[NTG-context] Hiding PDF-Layer

Hi, I want to include PDF layers in document and the should be hidden by default, the current behaviour is to show all layers I defined in my document and this should be later by the user and not when I open the file. The following shortened example from the modules show what I mean, the text "Text" can be seen when you open the document but it should appear only if you press the "VIDE" button. \starttext \setupinteraction[state=start] \defineproperty[L1][layer][title=layer 1] \button{HIDE L1}[HideLayer{L1}] \button{VIDE L1}[VideLayer{L1}] \midaligned {\definedfont[Mono at 150pt]% \startproperty[L1] TEST \stopproperty} \stoptext Wolfgang
