I've recently upgraded to the newest Excel package (v8.0.1 at the time of writing) and now all my reports which are exported to Excel and call the $this->dataStore() method throw the following exception:

Fatal error: Uncaught Error: Call to undefined method koolreport\excel\ExportHandler::dataStore()

Where has this function gone? How can I access data stores in my Excel template?

Many of my templates rely on accessing data stores directly (outside any widgets).

This is the piece of code that invokes the report run and it's export to Excel:

$reportClass = new MyReport();
$reportName = 'MyReport';
$reportClass->run()->exportToExcel($reportName)->toBrowser($reportName . '.xlsx');

And the file structure is as follows:

• MyReport.php: Report class file
• MyReport.view.php: HTML view file
• MyReport.excel.php: Excel view file

That fixed it, thank you!
