additional config required in order to use the grails datasource in reports

[jackradiance]

After setting useGrailsDatasource to true in the application.groovy birt configuration, I got an error saying that the dataSource was null. I was able to fix this by adding a line to the bean definition in resources.groovy (step 2 of the readme setup instructions)

birtReportService(BirtReportService, grailsApplication) {
    dataSource = ref('dataSource')
}

I figured this out by reading this stackoverflow answer:

https://stackoverflow.com/questions/21491074/grails-getting-the-data-source-in-a-normal-groovy-class

The author of the stackoverflow answer mentions that there are a couple of other alternative solutions that I believe could be implemented using either applicationContext or grailsApplication in BirtReportService.groovy

Thank you, @jackradiance, for the suggestion.

I remember having tested this and it worked -- at least when I released this version first. But of course, this depends on the way you use Autoconfiguration and so on.

I am quite sure, there are better ways to do this plugin. I just created it because I needed to migrate an old application which was still using BIRT. Fortunately we got rid of BIRT now, so this is for me a legacy project without maintenance.
