angularjs nginclude to a ReportServer url

angularjs nginclude to a ReportServer url

I am part of a team developing a custom SharePoint application that uses
AngularJS and SSRS Reports. Basically, the application allows the user to
select a report, select a set of parameters, and then view the report
within the site/app.
Everything worked fine until we turned on the report ToolBar. At that
point, the report stopped rendering. Only the toolbar was visible.
Here's what we are doing:
The html for the part of the app that displays the report:
<section class="left-panel report-view-panel ssrsReport show">
<h1>{{CurrentReport.Title}}</h1>
<button class="btn-report-close" ng-click="closeReport()"
type="button">Close</button>
<div class="scroll-list">
<figure class="report">
<div class="sample-report">
<div ng-include='CurrentReportURL'></div>
</div>
</figure>
</div>
</section>
In the controller javascript, we build out the report server url
(CurrentReportURL) to be something like:
http://ourreportserver.com/_vti_bin/ReportServer?http://ourreportserver.com/Our%20Reports/Report1.rdl&rs:Command=Render&rc:Toolbar=false&rc:Parameters=false&Param1=41001&Param2=08&Param3=0
We're telling it to render the report, hiding the toolbar and hiding the
parameter selection. This works fine. The report renders as expected.
However, changing the url to this:
http://ourreportserver.com/_vti_bin/ReportServer?http://ourreportserver.com/Our%20Reports/Report1.rdl&rs:Command=Render&rc:Toolbar=true&rc:Parameters=false&Param1=41001&Param2=08&Param3=0
causes only the toolbar to render. No report. If I copy that same url and
just open it in a browser window the report renders as expected.
I dug a little deeper and looked at both scenarios using Chrome and
Chrome's Developer Tools Network tab. There were several differences in
the calls that were made between the url in the ng-include and the url in
the browser window. However, the one that stood out the most was a POST to
RSViewerPage.aspx with all of the report viewer and report parameters
converted to the appropriate ReportViewer parameters. (I'd post that
actual link, but SO is telling me that I need a reputation of 10 to do
that).
I'm looking for some guidance as to why the ng-include version is not
making the POST? I believe this POST has something to do with the SSRS
Session that is only tracked with the toolbar is on, but I'm really not
sure.
Any guidance would be greatly appreciated!
