Hi, jan

I’ve been happy playing with jsolait since. J

Apparently, there is small bug with opera browser.

Any rpc call back  using async call would have failed in opera, where in other browser does fine.

If try to trace it, and find it here in urllib.js, in mod.sendRequest, line 245 (original urllib.js)

Xmlhttp apparently always null when called via opera.

This cause callback function cannot retreive return value from rpc calls

I havent try jsolait v2 because will require complete rewrite of phpolait

Best regards

Henry Eko

PS: cut down urllib.js

mod.sendRequest=function(type, url, user, pass, data, headers, callback){
