that line shouldn't be necessary: code/main.html is the default main script 
for webkit plasmoids. does it really not work for you without that line?

the places engine doesn't actually provide access to a service right now, so 
this isn't the API you need in any case.

you are correct: there is no serviceForSource in the binding. that should be 
added.

would you like to try your hand at doing so? it involves a bit of C++

in part this is because much of that API is senseless when using HTML where 
you already have a canvas and form widgets. 

but also in part because while i maintain the Javascript ScriptEngines fairly 
rigorously, there isn't someone who does the same for the WebKit ScriptEngine. 
people contribute to it sporadically, mostly to get it to do what they need 
from it.

no; documentation is lacking. it needs someone to read through the C++ and 
document it.

the code is in:

	kdebase/workspace/plasma/generic/scriptengines/webkit
