I have some problems generating a pdf. I need to generate a big table in a subreport, but in some cases this table freezes the generating process while loading. When any of the rows from the table is deleted, the pdf generates without errors (but it is missing the deleted row) (it doesn't matter which row gets deleted, this allows generating). We are using a XML imported from WebRatio as a source. It even crashes iReport when trying to see the pdf in iReport preview option ( Execute (with active connection) ). This problem is also avoided configuring each row to occupy a complete page but since the table is so big, a lot of space gets wasted so this solution will not work for our organization.
