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
