A quick answer:
In databaseworker.js:
What is ex.message? I think your error is here:
line: wp.sendMessage(ex.message,message.sender);
Try replace this line with
wp.sendMessage("Error: No valid data found. Data
was:"+serverresponse,message.sender);
And here, no error but a wrong feedback to the user:
eval("dataarr="+serverresponse);
wp.sendMessage("Error: No valid data found. Data
was:"+serverresponse,message.sender); //This line is only executed if
the eval goes ok, so it should return some ok status like "Valid data
found, start adding to local db"
Try and report back...
Sorry for my late reply, I been very busy lately...
