<Solved> Error: Name cannot begin with the ' ' character, hexadecimal value 0x20. Line 7, posi

[mvines]

After having a successful deployment of the Stimulsoft online toolset, I am starting to see the following error when attempting to load my reports into the web designer, or web viewer.

Name cannot begin with the ' ' character, hexadecimal value 0x20. Line 7, position 8.

It is thrown on this line
stiReport.Load(_report.FullyQualifiedReportName);

where _report.FullyQualifiedReportName contains a value like.
C:\Development\Files\Trunk\Reports\Private\80ba0ae5-311d-4c55-ab7a-1929f42be43b\49b2a8b9-6936-4831-9f2c-d72f054b9ee6\MVines Report 3.mrt
I have checked for the presence of white space around this value. It is not present.

In case this was a dataset issue, I distilled a report down to only one column in my dataset. The column name I am using is Case_CaseStatus, also verified not to have spaces in front of it.

Where does this error come from? What name is it suggesting has the issue?

Thanks for your time,

Matthew Vines

It is the Name element under DataSources that I think is causing the issue. This is how I am registering my dataSource when creating the report.

Code: Select all

stiReport.DataSources.Clear();
stiReport.RegData( "DataSource", _report.GetSchemaDefinitionDataTable() ); //_report.GetSchemaDefinitionDataTable() returns the data table used for the report without any data
stiReport.Dictionary.Synchronize();

I have found the issue, but do not know the cause of it.

Code: Select all

        
        
          IDNumber,System.Int32
        
        
        
        DataSource
      

What is the element name here?

Code: Select all

Why would it be missing?

One more piece of information for the puzzle. Apparently the problem started when I switched to

Code: Select all

_report.GetSchemaDefinitionDataTable()

before this issue, I was registering a dataset, I switched it to a data table because I only ever have one result set in my reports. This appears to be the source of the issue. I changed it back to a dataset and everything is moving along just fine.

This may be a bug in the Stimulsoft Report Serializer. There is an overload for RegData that takes a DataTable, but it does not appear to function correctly.

Element name is name of datasource. You can't use empty names in report.

Thank you.

Please check DataTable which returned by GetSchemaDefinitionDataTable method. TableName must be filled.

Thank you.

Thanks Jan,

That appears to have been the issue. Thanks for the reply.
