Failed to map the path System.Web.HttpException

[Adrian Tosca]

Hi All,

I hope you can help me with this.
I am getting a "Failed to map the path
'/avionics/X_T_c101p02_k0opy2zv5r4ebl45jmdrr1mv_mainArea.ascx'"
System.Web.HttpException when trying to execute the code below.

string test = Server.MapPath("/avionics/" + mainAreaTemplate);
where mainAreaTemplate contains
'/avionics/X_T_c101p02_k0opy2zv5r4ebl45jmdrr1mv_mainArea.ascx'

What is strange is that the exception appears at the 3'rd request. The
first 2 requests the code execute ok (tested with breakpoints to be sure
of this).

I also tried with other paths and is the same situation (eg:
Server.MapPath("ab/ab.txt"). It works a couple of times and then it
crashes. It is strange that the number of working times is the same each
time so it is not an random error.

The only way it seems to work is within a page in the application root
that makes Server.MapPath("ab.txt") - with no directory in the path.
This is indeed even more strange.

I am actually trying to make a LoadControl(path) and it seems that
LoadControl execute internally a MapPath. From this I come to my
example. So there is a problem with MapPath no with LoadControl.

Note that there is no other thread that runs in the application or other
similar thing (I read on forums that this can be an issue).

You can find below the full exception stack.

If you find any idea please help me

Some more info:

It seems that the problem appear only if the MapPath is executed on an
event that originated from a user control. If the same code is executed
elsewere (like for example on page pre render event) there is no
exception rised.

I used this info as a workaround (set a bool to true on the event and
execute my code on pre render).
