Setting params in code?

I have created three report parameters (problem, cause, remedy). I set them to a data row value as follows (fetch method of inner data set): 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>if (row["type"] == 'PROBLEM')
params["problem"] = row["description"];

if (row["type"] == 'CAUSE')
params["cause"] = row["description"];

if (row["type"] == 'REMEDY')
params["remedy"] = row["description"];</pre>
 
I want to reset the parameters to empty strings after displaying them, so I added the following code to the fetch method of the outer data set: 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>params["problem"] = null;
params["cause"] = null;
params["remedy"] = null;</pre>
 
This seems to work in the BIRT viewer, but when run it in Maximo, that code does not seem to be read. If the parameters do not receive a new value, they don't reset to null, they just continue to display what was stored in them last. 
 
Any ideas? I can explain better if necessary.

OK, I figured this out. I put the second code snippet in the beforeOpen method of the inner data set and it worked.
