User-Agent:       Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.0.04506; InfoPath.2; .NET CLR 3.5.21022; MS-RTC LM 8)
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel; Mac OS X 10.4;en-US; rv:1.9.b4)

WHen we create the control using script, we use the data="data:," tag to geenrate default data. This is to fix a bug where not dfoing this causes Firefox to make double requests for page data on instantiation of each control.

This works in FF 1.5 and 2.0 and has just broken in 3.0b4.

Reproducible: Always

Steps to Reproduce:
1. Navigate to http://www.etonline.com/silverlight/oscars80
2.
3.
Actual Results:  
The page asks you to install Silverlight even if you have it installed already.

Expected Results:  
Site should work normally, instantiating Silverlight control.

I think it wouldn't break in Firefox 3 Beta 4 if you included the MIME type in the data: URI.

Does it work in today's nightly build, now that bug 395110 is fixed?

Comment 2

I'll check latest build.

What would the data tag look like in this case? Our mime type is application/x-silverlight so what would a properly formatted data tag be? Bear with me as this is all new to me (an dI am new to the Silvelright team).

"data:application/x-silverlight,"

Comment 4

[Joe Jones]

No, latest nightly does not resolve my issue. I'll forward that on to the appropriate parties as well.

Comment 5

[Joe Jones]

Changing the data tag to what you recommend doesn't seem to fix the problem either.

Joe, are you still seeing this issue? That page you refered is not working anymore.
