Precompiled test case with source
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-GB; rv:1.9.1.3)
Gecko/20090824 Firefox/3.5.3 (.NET CLR 3.5.30729)
When running a precompiled site if browsing directly to a page in a subfolder
e.g http://localhost:8080/Folder1/sub.aspx prior to browsing to a page in the
root of the site e.g http://localhost:8080 a "an element with the same key
already exists in the dictionary" error occurs.
Reproducible: Always
Steps to Reproduce:
1. Copy precompiled test case into Mono environment
2. Start xsp2 from command line
3. Open browser and browse directly to http://localhost:8080/Folder1/sub.aspx
Actual Results:
The following error occurs:
Server Error in '/' Application
An element with the same key already exists in the dictionary.
Description: HTTP 500. Error processing request.
Stack Trace:
System.ArgumentException: An element with the same key already exists in the
dictionary.

Version information: Mono Runtime Version: /trunk/mono r143818 Fri Oct 9
15:34:19 NZDT 2009; ASP.NET Version: 2.0.50727.1433
Expected Results:
Page is returned normally and displays "This is a page in the sub-folder"
As the error states the problem is occurring in
System.Web.Compilation.BuildManager.FixVirtualPaths but specifically it seems
to relate to the fact that both 'global.asax' and 'index.aspx' are present in
our test case. In these two cases 'precompiled.Add' at line 197 will attempt to
add each of these with a 'new_path' value of "/" which consequently results in
the "same key already exists" error we see. However I don't think these files
specifically are related to the problem just any combination of two or more
files that will both have the same new_path value of "/" when FixVirtualPaths
is run.
I am using using r143818. I see the same behaviour when testing under Apache
also.
