Data exporting problem

Hi, 

Im having an issue passing data. It looks fine when in RM but when I export it goes a bit weird. 

My dataset has three attributes all with string values, with the first attribute having quite long string values ( 10000 words+). The dataset looks and works fine in rapidminer but when I try to export to csv some issues start to arise and after the 35th row it all falls apart. I think this problem is due to only being able to fit a certain amount of characters in one cell. 

This problem in itself is manageable, however, when I try to use the python operator on the dataset similar problems occur and from what I see in the log it would seem to be due to a similar problem (does the python operator export to csv internally?). 

So in summary I cannot use the Execute Python operator on my dataset. Am I missing something here? If not is there a workaround so I can operate on relatively big (not massive) bodies of text in a reasonably small dataset (2500 examples)?

Thanks

Alan
