Export to excel with no header row

[adalbero]

Hello,

I implemented an export to Excel from a ListGrid. But the generated XSL file does not have the header row. It leaves one row blank.

The RPC Request is:

{
"actionURL":"http://dev-win10-ag:8080/dim2/dim2/sc/IDACall",
"showPrompt":false,
"transport":"hiddenFrame",
"promptStyle":"cursor",
"bypassCache":true,
"data":{
"criteria":{
"a_status":"For Approval",
},
"operationConfig":{
"dataSource":"report_data",
"repo":null,
"operationType":"fetch",
"textMatchStyle":"exact"
},
"exportResults":true,
"exportAs":"xls",
"exportDelimiter":",",
"exportTitleSeparatorChar":"",
"exportFilename":"Test Report All.xls",
"exportPath":null,
"exportDisplay":"download",
"lineBreakStyle":"default",
"exportFields":[
"a_icon",
"object_name",
"a_status",
"document_language",
"lx_restrict_document"
],
"exportHeader":null,
"exportHeaderless":null,
"exportFooter":null,
"exportFieldTitles":{
"a_icon":" ",
"object_name":"Name",
"a_status":"Status",
"document_language":"Document Language",
"lx_restrict_document":"Restrict Document"
},
"exportDatesAsFormattedString":null,
"exportRawValues":true,
"exportCurrencySymbol":"$",
"exportHeaderSpans":null,
"exportOtherFields":{
"a_icon":" ",
"object_name":"Name",
"a_status":"Status",
"document_language":"Document Language",
"lx_restrict_document":"Restrict Document"
},
"exportWrapHeaderTitles":null,
"exportPropertyIdentifier":"title",
"appID":"builtinApplication",
"operation":"report_data_fetch",
"oldValues":{
"a_status":"For Approval",
}
}
}



The server generates this exception:

The request won't be enough to allow us to reproduce this, and we'll need to see a test case. We recommend that you start with a framework sample and change settings to match your app to try to cause the same problem.
