here's what we have.
in a stock D2W app there is a method in pageWrapper:
public String bodyClass() {
String result = null;
String pageConfig =
(String)d2wContext().valueForKey("pageConfiguration");
if (pageConfig != null && pageConfig.length() > 0) {
result = pageConfig + "Body";
}
return result;
}
Obviously it is setting the css class for the context. When I return from
making the jasper report pdf, the d2wcontect is null and there is the NPE.
as a work around, I added to the method that checks the context:
if (d2wContext() != null) {
NSLog.out.appendln("*** pageWrapper pageConfiguration is not null = *****
");
pageConfig = (String)d2wContext().valueForKey("pageConfiguration");
}
I get a very ugly page. now I can figure out why the compiled jasper report is
not using any of the fonts that I am specifying.
Are there any gotchas with the different versions of iReport and the version of
Jasper Reports in wonder?
