Javascript Error with match()

dbmathis

Hi All, 
 
I am using BIRT 3.7.2 and outputting to PDF. I have two different reports. The following code works fine with one report, however with the other report I get an error. Both are used in a data element. The one thhhhat works is a data element in a grid, the other is in a table. 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>var str = dataSetRow["userSelectList3"];
var re = /([A-Z]*)$/;
var n = str.match(re);

n[0];</pre>
 
dataSetRow["userSelectList3"] is a string and this code works fine. 
 
This however errors out in the second report. row["Organization"] is a string. Same code as the first report, but I get an error. 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>var str = row["Organization"];

//logToDebugWindow(str)

var re = /^(.*?\/)(.*)(\/.*)$/;
var n = str.match(re);

n[0];</pre>
 
I have verified that str is populated and not null. I just can't seem to figure out why this is not working? 
 
The error looks like the following: 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>org.eclipse.birt.report.engine.api.EngineException: A BIRT exception occurred. See next exception for more information.

Solved. Imports were breaking things.

Hi dbmathis,
 
I too have the same problem with my report. Can you please give some detail, about how you solved this ?
 
Thanks

Hi Rajanig,
 
I don't have any familiarity with the previous post, but my guess is that a Java package was being imported that contained a match() method and the imported method was overriding the standard JavaScript method. Another possibility when a basic JavaScript function fails to run properly in BIRT is that the Rhino JavaScript engine used by BIRT has a bug that is causing the function call to fail. It's unlikely, but it might be worth doing a quick search. Of course, most errors are basic syntax errors.
 
Regards,
Jeff
