BIRT Report: object not defined

It may not be obvious in the video - you need to add a hidden field (those two Total.count() in the video) to load the data set along with the JavaScript object in it. The same technique is also described in this developerWorks article, if you prefer reading.
http://www.ibm.com/developerworks/rational/library/10/creatingcustomreportswithbirtandrtc-part3/

Instead of specifying projectArea, use:
if (typeof(projectArea) == "undefined") {
    null;
} else {
    projectArea;
}

You can also try initializing projectArea = null;      in the report body initialize method.

Don, can you please attach the BIRT report design to illustrate the problem. I am having a hard time understanding the issue.

Hi, Rafik

Thank you very much for the reply. I am providing the procedures I am trying following your videos to explain more(I cant  attach the design file here,  no option to do that. Since I have to add many screenshots, comments won't allow me to do that, have to use answer here)


1. Create Work item dataset for custom severity enumeration

2. create severity dataset


3. Project area dataset from Common data source


4. Define projectArea in the script for project area dataset


5. pass projectArea; to severity dataset





6. when clicking OK, it complains projectArea is not defined(which I did define but it is not able to pass from different dataset(from Project Area to severity)


(detailed errors:
A BIRT exception occurred.
  Plug-in Provider:Eclipse.org
  Plug-in Name:BIRT Data Engine
  Plug-in ID:org.eclipse.birt.data
  Version:2.6.2.r262_v20110215
  Error Code:data.engine.UnexpectedError
  Error Message:Data engine operation failed due to an unexpected exception.
A BIRT exception occurred. See next exception for more information.
There are errors evaluating script "projectArea;":
ReferenceError: "projectArea" is not defined.
)

7. Now I set the default value of project area itemid in severity's parameter to '{Current Project Area}' to workaround the above error in order to move forward.
Create dynamic text to bind severity dataset, preview result looks ok.


8. Create new object and mapping following the instructions in the videos:


9.Create computed column in workitem dataset


10. It allows me to save but when previewing, it throws error that sev is not defined hence the computed column can not be computed. the problem seems to be similar to the previous projectArea not defined.



What did I do wrong in the above experiment? I follow the instructions in the videos although I do notice the BIRT version could be different. I installed the specified version in the 4.0.6 help. Please help. thanks a lot.
