Macro in JS: How to access ThisComponent-equivalent, run findAll

Hello,

I would like to execute the command "findAll" in a Javascript Macro. In
Basic, one can access thisComponent and access its findAll method (See [1])

However, the exposed Javascript API does not have thisComponent. I tried

  importClass(Packages.com.sun.star.frame.XDesktop)
  var currentComp = XDesktop.getCurrentComponent()

to get the current document (as described in [2])  but it failed
silently [3].

I also tried

  var desktop = XSCRIPTCONTEXT.getDesktop();
  var comp = desktop.getCurrentComponent();

…which gives me something, but that returned object does not have the
findAll-Method.

How to run findAll() in a JS Macro?


Kind regards,
 Jan

console. Whyever.
