There are errors evaluating script [message #996764]

I have been assigned to clean up a project for a client that uses BIRT reporting. I have fixed most of the issues but I still have one report that is not working and is returning an error. The error is:

Row (id = 1467): 
+ There are errors evaluating script "var fileName = row["Attached_File"];
params["HyperlinkParameter"].value = ImageDecoder.decodeDocs(row["Ecrash_Attach"],fileName);":
Wrapped java.lang.NullPointerException (/report/body/table[@id="61"]/detail/row[@id="70"]/cell[@id="71"]/grid[@id="1460"]/row[@id="1462"]/cell[@id="1463"]/table[@id="1464"]/detail/row[@id="1467"]/method[@name="onCreate"]#2)

I can post the full stack trace if someone wants it but for now I will omit it since it is very long.

Here is the source of the decodeDocs method:

public static String decodeDocs(byte[] source, String fileName) {
        String randName = "";
        byte[] docSource = null;
        if ( Base64.isArrayByteBase64(source) ){
            docSource = Base64.decodeBase64(source);
        }
        documentZipPath = writeByteStreamToFile(source);
        randName = writeByteStreamToFile(docSource, fileName);
        return randName;
    }

I am pretty well lost on this one. The error looks to be telling me there is an error on line two of the script which is:

var fileName = row["Attached_File"];
params["HyperlinkParameter"].value = ImageDecoder.decodeDocs(row["Ecrash_Attach"],fileName);

This is written in the OnCreate method of the report. Any help, even clues would be greatly appreciated. If you would like to see the report just ask and I will post the xml for it.

Can you post the full stack? You can probably put it in a text file and attach it to keep from expanding the post.

Do you possibly have any null values or special characters or something that are being passed to the file writer?

I don't think so. To me this script looks like it is getting an image file name that is in the current data. This is obtained by passing in an ID number associated with the table. I think this is then passed in to the decode method so that it can be viewed. I also thought something was null but the only things that could be null would be the ID or the possible absence of an image in the row. I went to the database and checked the table and the image is there for sure. The report will populate the text data so the ID number is getting passed successfully, it is only this script which handles the image that is not working.

So, no values in the row["Attached_File"] field have null values? I still would say the error is suggesting something along these lines. You might look into the line where writeByteStreamToFile is called without a fileName, yet the line below it has one. I don't know the code behind the function, so I don't know if this is handled.
