I have a simple list report with 2000 records working fine and takes about seconds to render!
But when I add a Date field (datetime nullable), the report become very slow to render, taking about 4 minutes to render.
I delete Date field and report works fine again. No sorting, no interaction, just a simple list.
If i change Date field from datetime nullable to datetime in the dictionary, reports works fine with the date field!
I took a look at debug output during rendering and I see the errors listed at the files attached.

Hello.

Please, check if you set the type of the column to DateTime (nullable).
For some data sources could be the issue with parsing of date.

Please, try our latest build and if you still get the issue, please, send us your report template with sample data.

Thank you.

Hello,
Actually I had to set all columns from DateTime (nullable) to DateTime.
All my reports with DateTime columns are now rendering too much faster!!!

I think here is some problem setting DateTime(nullable) in the dictionary that is slowing reports to render.
But for me the problem is solved anyway!
Thanks!
