List Component

[baggypants]

I got the new list component working today with a bit of careful thought and without any documentation at all, congratulations on your design.

I wrote about it here so I would remember what I did.

Cool, thanks Baggypants!  Yeah, I love the new List component, it's almost a light subreport!

I used the List component in this video tutorial:
http://jasperforge.org/website/ireportwebsite/IR%20Website/tutorials/Dashboard/Dashboard.html

I added your article to the iReport wiki:
http://jasperforge.org/plugins/mwiki/index.php/Ireport

Thanks again, I hope other people like you will share some documentation in the future!

Hi all;

I am trying to use the List component in a report design that uses an xml data source.

The goal is to interate over set of child nodes and display related data.

Can you help me please ?

Hi,

 

I really like the list component, but I'm getting some trouble doing one thing:

 

For each record in my main datasource, I'll display a sub-listing, using the list component.

 

On the dataset1 (the one linked to the list component), I've set a variable $V{listTotal} that will SUM a specific dataset1 field, let's say $F{ammount} which is a BigDecimal. It is set to reset at Report level, so for each list iteration (once for each main datasource record) it will start with value 0.

 

Perfect!

 

Now I have a problem ... I need to SUM all those sub-totals, so I can display a TOTAL at the end of the report ... but I can't seem to create a text field that can link to those dataset1.listTotal values ... or better still, I can't find a way to pass the listTotal value to a global SUM variable, so I can display it at summary band, or something ...

 

Any way of doing it?

 

Thanks

Hi,

I am using the javabeans datasource to generate my report. It works fine until it encounters an arraylist. How can I display the items in this arraylist? It contains custom objects with custom properties. I wanted to use the List Component for this, but how do I use it?

Can you help?

Thanks in advance,

Regards,

Hi Giulio,

I tried to mimic your dashboard demo and got a problem with the list component. As soon as I set the dataset to allow more than 1 row, the parent frame height is pushed out by the (number of rows) * the list height.

Any idea what I could do wrong?

Thanks in advance.

 HI everyone,

I want to use a scrollable list component.I am able to use simple list but it restricts me to show all the records due to its dimensions(height). So I want to add a scroll so that I can show as much records as per the requirement of the report.

 

Thanks.
