Is there a Cascading Input controls workaround?

[kmansfield]

I see posts on users asking about the cascading input controls and that it is currently not supported by jasperserver. I wonder if anyone has a good work-around and a sample code on how to do this?

 

Cascading input controls for example allow user to select a country in the first control and then a city select auto-populates in the second control based upon the user's country selection.

 

Here is a post with more information on the cascading enhancement. cascading input post

 

I'm also tempted to contribute a more formal solution to the project, but I doubt my boss will give me the time and thus need to do a work-around first. Are there any proposed architecture in case I have more time?

 

Thanks,

 

Keith

We know we need to do this, but have not started work on it.

 

You could have a custom parameter JSP page that does the cascading logic.

 

 

 

In general, this would be an extension of the Query based input control, with a concept of columns being in levels 1-n. There are a couple of alternative displays of this.

 

1. Drop down boxes, 1 per level.

2. A multi-select version, so you could select cities from Bulgaria and Austria, say.

 

Validation could be controlled so that all levels have to be selected, or only the first N levels.

 

Apart from cascading controls, folks have been asking for cross control validation and the ability to order controls on the page/dialog box.

Vishal;

Set the custom parameter page on the report unit where you want to use the cascading logic to your new page. Have a look at WEB-INF/jsp/DefaultParametersForm.jsp to see how you can link up to the parameters of the report.
