Dynamically created tables causing object reference not set to an instance of an object

[Anders]

Hi
--------------------------
EDIT:
I am really sorry for the long post, tell me if you want it to a pastebin, the problem here after some debugging is that the structure seems ok after going through properties when opening it in debugging mode, the really big problem for me is that I canot get any kind of output from the report telling me what is wrong and why it's thinking there is no report. like some kind of exception catching
--------------------------
I am using the Q2 2010 SP1 4.1 and telerik radcontrols for winforms Q1 2012 SP1 and I just created a report by using some dynamic coding in the report(which is embeded in a winform), at first I copy pasted and edited a lot from some code made in designtime, however as this resulted in ugly (but working) code I created a class to do it for me however it now shows no report, just a message saying "Object reference not set to an instance of an object."

this is my weekreport.cs class containing the definition class for the report, the uglypopulate method is the one which works, the almostpopulatelikeabaws is the new code I created with the help class

I also attached a picture of how the report looks once generated, I removed the names of the customers though hope you don't mind

any help is appreciated :)

Update:
I tried adding this code block just to test if it was the generator class or the code using it that was the problem, and it's the generatorclass. This is the code I used to show one row with and I still got the problem

                      new Unit(4.5999999046325684D, UnitType.Cm));
            SizeU s = new Telerik.Reporting.Drawing.SizeU(new Telerik.Reporting.Drawing.Unit(12.600000381469727D, Telerik.Reporting.Drawing.UnitType.Cm), new Telerik.Reporting.Drawing.Unit(2.4000000953674316D, Telerik.Reporting.Drawing.UnitType.Cm));
            ReportTableGenerator rg = new ReportTableGenerator(s, l, new Telerik.Reporting.Drawing.Unit(0.6D, Telerik.Reporting.Drawing.UnitType.Cm));
            rg.Nextbox.Value = "ctest1";
            rg.addColumn(new Unit(0.6D, UnitType.Cm));
            rg.Nextbox.Value = "ctest2";
            rg.addColumn(new Unit(0.6D, UnitType.Cm));
            rg.Nextbox.Value = "row1";
            rg.addRowCell();
            rg.Nextbox.Value = "row12";
            rg.appendRow();
            rg.finishTable();
            DetailSection.Items.Add(rg.table);
