+
+Please fill in this template when reporting a bug, unless you know what you

+Description of Problem:
+
+System.Web.UI.WebControls.DataList not working - running from cvs on
+mandrake 9.1 --- updated mono/mcs/xsp modules all on 2004-03-23...
+
+Steps to reproduce the problem:
+1. add asp:DataList to form
+2. view form in browser
+3. enjoy Error 500 while contemplating another solution without a datalist....
+
+Actual Results:
+
+System.NullReferenceException: Object reference not set to an instance of
+an object
+in <0x0000f> System.Int32:FindSign
+(int&,string,System.Globalization.NumberFormatInfo,bool&,bool&)

+in <0x0011f> CreateHandlerState:Execute ()
+in <0x0007e> StateMachine:ExecuteState
+(System.Web.HttpApplication/IStateHandler,bool&)
+
+Expected Results:
+
+three broken images and three links to some file...
+
+How often does this happen? 
+
+always... same code compiles and runs in Framework 1.1... this error
+happened with the tabcontrol2.aspx sample as well, i think. its probably
+more fundemental than the datalist itself...
+
+Additional Information:
+
+Sample Code: this (or similar code) could be checked in to the xsp/test/
+folder
