Option choices for input controls don't appear

[Jasperiousity]

The available choice names for my input controls are not showing. I am not sure if it's the way a set the input controls. Also I would like to use a dropdown list instead of a checkbox. How can I correct these issues. Please see the current look in the image below.

I am thinking that you are not seeing any values, because in your definition of your input control, on the Set Parameter Values page, in the Visible Columns entry, there are no columns shown.  Probably you entered a column, but didn't press "Add".

When editing the input control, under Type, there are many different input control types. You probably want your input to be of type "Multi-select Query".

Thanks for replying. I followed your instructions and now I'm getting Null for the options in the "Multi-select Query" and I also added the visible columns.

Here is a screenshot.

 

I also used the following query which has two options which I added as the visible columns. In JasperReports Studio, I created a parameter of Class java.util.Collection with the "Default Value Expression" of new ArrayList(Arrays.asList("Subscription", "Redemption")). These are the values I expect to see but appear as null. 

SELECT DISTINCT tran_type FROM prov.ATrans ORDER BY tran_type

Your "Select Distinct tran_type...." query was defined using the proper data source (in the Link a Data Source to the Query page in JS Server)?
And when you run your query in your database (in like SSMS), two of the values in it are always "Subscription" and "Redemption"?
And you added "tran_type" as a Value Column and you added "tran_type" as a Visible Columns (in the Set Parameters Values page in JS Server)?

"[Null] | [Null]" in your results (the two [Null]s) that indicates to me that you ADDed two visible columns to your input control, but your "Select Distinct..." statement only returns one column.
