WinXP 32, FPC and Lazarus latest SVN checkout.

I was trying to play a little bit with the promising new fcl-web webdata 
features to see how JSON/EXTJS works with FPC/Lazarus and came up with 
the following problems in the first demo example


1. The project source files in there contains a line something like:

{$IFDEF WINDOWS}{$R somethinghere.rc}{$ENDIF}

This gives an error message during compile in Lazarus that the .rc file 
is not found. When commented out, they compile OK.

2. When loading the extgrid-json.html into my browser, the grid comes 
up, but only says "No data to display" and the data.xml debug file contains

"{ "success" : false, "message" : "Unknown web data input adaptor name: 
\"\"" }"

(the CGI program has access to the users.dbf file, in fact this dbf file 
is regenerated every time the html page is loaded)

3. When loading the extgrid-xml.html , there is a popup error message 
with the same 'Unknown web data input adaptor name: ""' message. The 
data.xml debug file has
<?xml version="1.0"?>
<dataset success="false">
   <message>Unknown web data input adaptor name: ""</message>

in it.

I could not yet figure out what the problem is due to limited time at 
the moment (2:00AM), any suggestions would be welcomed to find the
