Hello, I have to create a jasper report where in I have one fixed column with fixed field names but remianing columns can vary based on what product the end user selects. So I will have FieldName , FieldValue,FieldValue, ...,FieldValue(n) columns. The FieldValue fields are calculated on the fly based on the products. I searched on the net about it and most of the threads are dated back in 2006. They asked to use Valocity with Jasper to create Dynamic columns but I do not have example. Any pointer as to how to create such columns in this case? In my project we use .jrxml files. thanks
