I was asking Jan Blok by mail:
'Jan, can you please make a build where we can export a solution with more than 10.000 rows? That would save us a lot of work!'
Exact 5 minutes later, I received his email:
'Allready possible, add this:
servoy.maxSampleDataTableRowCount=100000
in the servoy-properties file'
SERVOY ROCKS!
