Thanks Ann again for your response.YOU really are giving some very good suggestions.
However, my senerio is little bit different here - Actually my List contains all the field Name whose bg color needs to be changed in the PDF. So lets suppose there are 50 fields I am displaying on the report, based on the list I just need to highlight the one which are present in the List.
So what I understood as of now is -
> I will define a style for every field
> include Conditional style, this will have conditional expression as paramList.contains(" ")
> include this style to the field.
so I will have as many style present as no of fields, SO EVERY field will have different style. I cannt use multiple conditional tag in same style as the list contains name which I am comparing it against my hardCode Field name.
But, I wanted a way out if I can limit the style tag definition to one and with only one conditional tag and all the field use that.
Please let me know if the problem statement is still not clear?
Thanks for looking into this!
