Argument types do not match

[Kokanovic_Vjeran]

Hello,

When I'm adding collection without elements (Count == 0), exception "Argument types do not match" is thrown on Report.Run

Eg.

IEnumerable<SomeType> collection = DataFetchFunction();

XlsFile xlsFile = new XlsFile();
xlsFile.Open(reportPath);
FlexCelReport report = new FlexCelReport();
report.AddTable("SomeName", collection); // collection.Count() == 0
report.Run(xlsFile);

Thanks in advance, and happy new year to everybody.

Hi,

I have been trying but I can't see to reproduce the error.

One of the things that I tried:

   class Test0
    {
        public int Value{get;set;}
    }
   
    public void Test0Lines()
    {
        using (FlexCelReport fr = NewFlexCelReport())
        {
            IEnumerable<Test0> data = new List<Test0>();
            fr.AddTable("t1", data);
            fr.Run(zConsts.Read4 + "zrolinq.xls", ZConstsWrite + "zerolinq.xls");
            fr.DeleteEmptyRanges = false;
            fr.Run(zConsts.Read4 + "zrolinq.xls", ZConstsWrite + "zerolinq1.xls");
        }
    }

The template is just a <#t1.value> tag inside a t1 name.

but all the other things I tried seemed to work fine. Is there something else you can see that might be causing this? Any sample code you can send me? (to adrian@tmssoftware.com)

I'm sorry. Code example wasn't complete.
This is all thing:

            IEnumerable<DefinicijaMjerenjaEntity> definicijaMjerenjaCollection = new List<DefinicijaMjerenjaEntity>();
            IEnumerable<IzvrsavanjeMjerenjaEntity> izvrsavanjeMjerenjaCollection = new List<IzvrsavanjeMjerenjaEntity>();

            XlsFile xlsFile = new XlsFile();
            xlsFile.Open(reportPath);

            FlexCelReport report = new FlexCelReport();

            report.AddTable("DefinicijaMjerenja", definicijaMjerenjaCollection);
            report.AddTable("IzvrsavanjeMjerenja", izvrsavanjeMjerenjaCollection);
            report.AddRelationship("DefinicijaMjerenja", "IzvrsavanjeMjerenja", "DefinicijaMjerenjaId", "DefinicijaMjerenjaId");

            report.Run(xlsFile);

It seems that problem is in relationship, because when I comment line

            //report.AddRelationship("DefinicijaMjerenja", "IzvrsavanjeMjerenja", "DefinicijaMjerenjaId", "DefinicijaMjerenjaId");

report is rendered without exception.

I've refactored code. Now I'm using implicit relationship, and everything is peachy.

Hi,

Thanks for the example, there was indeed an issue if the relationship was in a value type and thre were zero records.

We have fixed it internally, and it will be available in next release. If you need an urgent fix please contact me by mail.
