hi,

I've just started using crystal reports XI and have been atleast successfully integrated it with our struts webapp, however, I'm still having problems when clicking one of the buttons in the reports itself like the zoom list, pagination & etc. Anyone here to know how to resolve this? I've already tried opening a new window when generating report by using target="_blank" to decouple struts and crystal reports but the problems still the same. Below is the sample error when clicking(changing) the zoomlist:

org.apache.jasper.JasperException
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:254)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:295)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
org.displaytag.filter.ResponseOverrideFilter.doFilter(ResponseOverrideFilter.java:125)

root cause

java.lang.NullPointerException
org.apache.struts.taglib.tiles.InsertTag.processAttribute(InsertTag.java:687)
org.apache.struts.taglib.tiles.InsertTag.createTagHandler(InsertTag.java:478)
org.apache.struts.taglib.tiles.InsertTag.doStartTag(InsertTag.java:438)
org.apache.jsp.cssLayout2_jsp._jspx_meth_tiles_insert_0(cssLayout2_jsp.java:471)
org.apache.jsp.cssLayout2_jsp._jspService(cssLayout2_jsp.java:187)
org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:137)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:210)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:295)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
org.displaytag.filter.ResponseOverrideFilter.doFilter(ResponseOverrideFilter.java:125)


any help would be greatly appreciated.

thanks,
