Error Rendering trough Web Service to WebArchivo format

Hi,
We are using the Reporting Services Web Service, in order to expose some
reports in our Web Application, right now I am trying to enable exporting the
report to the available formats in Reporting Services, and altough everything
seems to be working fine, when I try to render as Web Archive, I get the
following exception:
Exception of type
Microsoft.ReportingServices.ReportRendering.ReportRenderingException was
thrown. --> The parameter is incorrect.
first I tough it was because of the device info configuration I was using,
since it was the same of the html format (which had things like turning off
the toolbar), thus I instead didnt pass any deviceinfo(null), in both cases
it works fine in all formats but it doesnt in Web Archive.
I have been searching for info about the error, but I havent found any ...
if anyone knows what is happening, I will be thankfull :) ... in the mean
time, I will keep trying, and if I find anything I will post it here.I have continued digging on the problem, I havent found anything on the
internet, and I have cleared out some things about the problem ...
so, here are some aditional info about the problem:
- it isnt only happening when I try to render the report trough the Web
Service, it also happens when I use url access.
- it is happening specifically in this report, there are other reports that
works well
- I am not using any totals/subtotals formulas (I say this, since I have
read this might cause trouble in certain rendering extensions)
- I just found something else (I have 3 reports):
- the report that is working doesnt receive any parameter
- the 2 reports that doesnt work receive 1 parameter, and additionaly have
a list of valid values ...
it looks like it were a bug, something along the lines that rendering
extension either ignores the parameters, or gets confused where there is a
list of valid values ...
Any help will be greatly appreciated ... in the mean time, I will be playing
with the reports definition, in order to find what is exactly happening, if I
dont find a solution soon I will restrict that rendering extension from being
used :(:(:( ...|||I am done with this, I am pretty certain is a bug, just not the type of bug I
tough ...
it is really weird, I played with the parameter options in the report and
the error kept happening, then I decided playing with the report design ...
well, whenever I put a third column in my report, the error happens when I
try to export it to web archive ... I put all types of definition in the
third column, to see if I managed to see anything making it fail, but didnt
arrive to anything, I tried from the simplest one (static text + no
formatting) all trough a "complex" one (formatting + dinamic text ...)
