Hi dirk.
I create a create a nattable with a huge columns.when i execute the nattable, it still run in painterLayer in NatLayerPainter.java again and again. like a deadloop, when i set a small column count, it is right. do you know where control this function? can you give me some advises for that.
reproduce:
run attachment file _5016_AutomaticHugeDataSpanningExample
add a log in painterLayer function in NatLayerPainter.java,
we can find , it will run this function again and again. like a dead loop.
can you help me check it? thank you very much.

might be related to how spanning works in NatTable since every cell is rendered once, and a spanned cell in your case consists of several hundred cells.
Maybe you are trying to implement a pivot table, I don't understand what you are trying to do. But personally I think you are running into the wrong direction. Maybe instead of trying to rape the existing code you should try to implement a custom layer or a custom functionality to do what you are trying to achieve, but surely rendering 1000 columns in 500 pixels will never work in a clean way since there is so much that can go wrong or cause strange behavior in the current architecture.
