Hi David,
Thank you for response.

I have tried that. It doesn't work.
Here is my parameter:
<scalar-parameter name="departmentID" id="11">
<property name="valueType">dynamic</property>
<property name="dataType">decimal</property>
<property name="promptText">Department</property>
<property name="format">Unformatted</property>
<property name="controlType">list-box</property>
<property name="dataSetName">departments</property>
<expression name="valueExpr">row["ID"]</expression>
<expression name="labelExpr">row["Name"]</expression>
<property name="mustMatch">true</property>
<property name="fixedOrder">true</property>
<property name="defaultValue">9</property>
</scalar-parameter>
------------------------------------------------------------ -
here is "departments" DataSet:
<oda-data-set
extensionID="org.eclipse.birt.report.data.oda.jdbc.JdbcSelectDataSet "
name="departments" id="6">
<property name="dataSource">midwood</property>
<property name="queryText">select ID, Name
from dbo.Department
order by name</property>
</oda-data-set>
I need to show selected department name.
Thank you,
Vladimir

I see what you're asking now. The parameter is really the department id.
You don't really have a handle to the combo parameter 'name' part. You have
params["department-id"], but nothing for params["department-name"] as it's
displayed to the user, but it isn't a param per se.
What I do is a bit different. I use the DepartmentID to index into my
departments table to return a dataset for my report. As part of that, I
also return the department-name in dataset query even though I may not
actually need it for the report. Then I display that in my report header as
row["department-name"]. Will this work for you?
So what I have is actually two datasets:
1. dataset departments which is used to form the parameter with query:
select ID, Name from dbo.Department order by name.
2. dataset department which is used in my actual report with query: select
ID, Name from dbo.Department where ID=? <bound to parameter DepartmentID>
and used to display the department name in my report.
is this clear?

Yes it's clear. In fact I use the same approach as you.
Only instead of second query I'm using "getDepartmentByID" stored procedure
with related parameter.
But it doesn't look for me as elegant solution.
We have to use additional dataset and additional report item such as table
with additional parameter bounding just to work out the issue.
I have suggestion to file enhancement. What do you think?
In case you agree with me on this, please make enhancement.
I will add comments later to show them it's not just one developer who need
that enhancement.
Thank you,
Vladimir
