2002 JI Open Discussion Posted August 27, 2006 Share Posted August 27, 2006 By: Betuca Buril - betuca multivalue parameter 2003-03-13 13:22 Hello people! I was trying to use Jasper with Ireport and i?ve got some questions. When i use a database connection with a SQL select it works realy fine. I used a field on the IReport toll ($F{field_name}). In another java class i needed to use a list of parameters, but i cant make it work. Does anyone knows how can i put on the report an Array( collection, list, ...) on a parameter? Thanks for your help By: Teodor Danciu - teodord RE: multivalue parameter 2003-03-13 13:40 Hi, This smells like subreports combined with JRBeanCollectionDataSource. You can pass your collection as a parameter, but you need a subreport to iterate on it and generate some output in the master document. Check the "subreport" and the "datasource" samples. I hope this helps. Teodor By: Enrico Goosen - enricogoosen RE: multivalue parameter 2003-03-13 22:59 Further to what Teodor wrote... Remember to set the parameter class to "java.lang.Object". Then cast it to the appropriate Type. In my report I pass a HashMap as a parameter. I've got a scriptlet that uses the HashMap to display totals in the Summary section of the report. This might be useful in your case...if so, check out the scriptlet example, in the samples section. Regards, Enrico By: Betuca Buril - betuca RE: multivalue parameter 2003-03-17 12:19 Thank you guys!
