chart development and testing

[samp7673]

So I am doing chart development and my goal was to avoid having sql statements in jrxml files. I was relying on an example of going from a struts action to generate the report where a list of beans is passed in that is set up in the config file. I am confident the beans contain data and I've had some success doing this but as development gets more complex I don't know what to do about the java.lang.IllegalArgumentException: Null 'key' argument errors. The stack trace in the browser is not givng me much to go on; specifically what field is causing the problem. How can I tell what field it's complaining about? Right now, I have been using a sql query off a database to do development of layout than switching to the list of beans for integrated testing. I strip out the <query> taq when I do this. Is this not the correct way to do this work? I do not think the group architect will allow for straight sql off the database from within the report.

Hi,

 

You have to show us this exception stack trace. Maybe we can figure out something from it.

 

Thank you,

Teodord,

  I think I find it for now. When drawing up the report in iReport, I was retrieving content from a jdbc connection. I guess how I was receiving it was not too important but in the field declarations at the beginning of the report, each field had a child with description. I had another example that was working. I noticed it wasn't using descriptions. So I cut those. Also, I cut the doctype statement at the type. I also had to cut the query element out as well being that I was passing in a collection of beans.
