Getting an incorrect permissions screen in the webview Blackberry 10 Cascades Beta 3 SDK in Dev Alpha Simulator - c++

Question

I am trying to make dynamically generated html 5 graphs show up in a webview in Blackberry 10 Cascades. I have confirmed the html5 that I have generated, draws the correct graphs. My problem is that when I try to implement this in the Blackberry 10 Cascades Beta 3 SDK (using the Blackberry 10 Dev Alpha Simulator), the webview that is supposed to show the graph, just looks like this:
Here is the code that leads to this error:
//html_ already contains the html-5 code to make the graph at this point in the code
//This is the file path to a local file that is actually accessable in the emulator
//and not just from Windows
//
QFile *chartFile = new QFile("app/native/assets/data/chart.html");
if (chartFile->open(QIODevice::WriteOnly)) {
chartFile->write(html_.toUtf8());
chartFile->flush();
chartFile->close();
}
if (chartFile) delete chartFile;
if (graphView_) {
graphView_->setHtml("");
graphView_->setUrl(QUrl::fromLocalFile("app/native/assets/data/chart.html"));
}
I checked the permissions of that file, put they are all Allow (777 permissions for those who know Unix style permissions).
I added access_internet to the bar-descriptor.xml, eventhough my app was already able to access remote sites, just to see if that would fix it, but it did not.
I've been searching around trying to find a solution to this problem, but I have not.
If anyone could help me out with this, it would be greatly appreciated.
-------------------------------------------------------
Update:
I changed the code to set the html directly, now I have this:
if (graphView_) {
graphView_->setHtml(html_, QUrl("app/native/assets/data/chart.html"));
}
But nothing shows. It seems I have the wrong relative path relative to my base url.
My base url is this: QUrl("app/native/assets/data/chart.html")
My relative paths all begin with: ./Highcharts/js/...
My relative paths are located under: app/native/assets/data/Highcharts/js
It seems to me that I this should work, but when I do this, I just a blank screen, as if it can not find my relative paths. So I don't know what's going on here either.

Answer 1

I found a solution that works. I'm using the first approach, not the updated approach, but instead of
graphView_->setUrl(QUrl("app/native/assets/data/chart.html"));
I'm using:
graphView_->setUrl(QUrl("local:///assets/data/chart.html"));
And I have left the rest of the code the same, and it works.
