Phonegap: BarcodeScanner & Childbrowser plugins - ios

Question

I'm facing a problem using this 2 PhoneGap plugins: "BarcodeScanner" & "ChildBrowser" (inside an iOS app, with XCode 4 & PhoneGap 2.0).
I've a button "Scan" on my app UI. When the user clic on this button, the barcode scanner is launched.
So, in the Success function of the barcode scanner callback, I need to open the recovered URL from the scan in a new Childbrowser window (inner the app).
But the new Childbrowser window is never been opened, while the console displays "Opening Url : http://fr.wikipedia.org/" (for example).
Here is my JS part of code:
$("#btnStartScan").click(function() {
var scanBarcode = window.plugins.barcodeScanner.scan(
function(result) {
if (!result.cancelled){
openUrl(result.text);
}
},
function(error) {
navigator.notification.alert("scanning failed: " + error);
});
});
function openUrl(url)
{
try {
var root = this;
var cb = window.plugins.childBrowser;
if(cb != null) {
cb.showWebPage(url);
}
else{
alert("childbrowser is null");
}
}
catch (err) {
alert(err);
}
}
And all works fine if I call my openURL() function inside a Confirm alert callback for example, like this:
if (!result.cancelled){
navigator.notification.confirm("Confirm?",
function (b) {
if (b === 1) {
openUrl(result.text);
}
},
'Test',
'Yes, No');
}
But I need to launch the ChildBrowser window directly after a scan, without any confirm alert etc.
Does anybody know how to solve this please?

Answer 1

I also have this same problem.
Solve it by set timeout.
var scanBarcode = window.plugins.barcodeScanner.scan(
function(result) {
if (!result.cancelled){
setTimeout(function(){ openUrl(result.text); },500);
}
},
function(error) {
navigator.notification.alert("scanning failed: " + error);
});

Answer 2

I'm running into the exact same problem.
My application also has another mechanism to show a webpage besides the barcode reader and when I do that action I can see that the barcode-related page HAD loaded, but it never was shown.
In ChildBrowserViewController.m, I'm looking at the last line of loadURL() which is webView.hidden = NO; and I'm thinking that the child browser is set visible after we barcode but something about the barcode reader window caused the child browser to get set to the wrong z-order, but I'm not familiar enough with the sdk to know how to test that or try to bring it to the front.
Hope this helps target a potential area.
