any method to know what parameter's value is passed to the subreport?<br />
<br />
I have a table and in a column of detail band, I add one more table as subreport.<br />
the main report dataset is SingleServerOverload and the subreport dataset is HelpdeskTicket.<br />
In the HelpdeskTicket, the query has three parameter like following:<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>
select
TICKETID,
CREATIONDATE,
DESCRIPTION,
STATUS
from SR
where
(LOCATE(?, classificationid) > 0 )
and CREATIONDATE > ?
and CREATIONDATE < ?
</pre>
<br />
and in the subreport table, Dataset parameter Binding, I define the following<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>
param_1:row["DATE"]
PARAM_2:ROW["helpdeskStartdate"]
PARAM_3:ROW["helpdeskEnddate"]
</pre>
<br />
then in the subreport dataset HelpDeskTicket beforeOpen event, I want to know<br />
what value is passed to the subreport parameter, so I write<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>
Packages.java.lang.System.out.println(row["classificationID"].value);
Packages.java.lang.System.out.println(row["helpdeskStartdate"].value);
Packages.java.lang.System.out.println(row["helpdeskEnddate"].value);
try {
Packages.java.lang.System.out.println(param_1);
}catch(ex){Packages.java.lang.System.out.println("catch println(param_1)");}
try{
Packages.java.lang.System.out.println(params["param_1"]);
}catch(ex1){
Packages.java.lang.System.out.println("catch println(params[\"param_1\"])");
</pre>
but the first three println cannot show the value of parameter, and the later<br />
two println show exception and go to catch statement.<br />
So any method to know what parameter's value is passed to the subreport?<br />
(because my subreport seems cannot run properly)<br />
<br />
thanks in advance.
