missing "KMPicker.htm" file for TinyMCE editor in WPC in 7.3

Hey experts,

does anyone have the source file "KMPicker.htm" for the TinyMCE WPC integration?

I was able to integrate the TinyMCE editor into the web page composer in Portal 7.3 and fixed all problems.

I wrote my own custom file browser for the KM integration for links and images. I can remember there was a "KMPicker.htm" file which includes the KM screen. But I cannot find it anymore although I thought the internet does not forget ;-)

I know that there is something with

loadFrame.src = "/irj/go/km/navigation" + startURI + "?rndLayoutSet=pccLinkSelector&StartUri=/" + startURI;

and a funktion "tryToGetStartUri()" with var uri = "/pccdesign"; // default

Please help

Thanks a lot and greets,

Steffi
