#37 setWhenNoData - Returns blank reports

[Brian Swain]

using the drb.setWhenNoDat(WHEN_NO_DATA_TYPE_NO_DATA_SECTION); or the drb.setWhenNoData("NO RECORDS FOUND", noDataStyle); returns an empty Jasper report with no pages.

The report should contain the report minus the detail section. If the drb.setWhenNoData("NO RECORDS FOUND", noDataStyle); is used it should contain the text "NO RECORDS FOUND";

[Juan Manuel Alvarez]

thanks for reporting...

this is really an issue, nobody touch that part of code since long ago...

which version of DJ are you using?

[Juan Manuel Alvarez]

Hi there, I cannot reproduce the problem.

I run the test ar.com.fdvs.dj.test.WhenNoDataTest and it goes whell with any version the the overloaded method setWhenNoData(...)

can you please describe version of JR, DJ and if you are using a template JRXML?

[Brian Swain]

We are using the newest beta2 jar of DJ.
THis is the JRXML file:

It appears the issue is when a template is used. If I remove the template from my code, I get output. Please verify you can replicate this issue.

DJ,

The issue appears to be that even though I set the parameters for setWhenNoData, the generateJasperDesign code does not set these values if there is a template present.

I would like the ability to have a template with basic desgin but still be able to set the parameters to the DRB.

Also shouldn't there be the ability to have the WhenNoDataAllSectionNoDetail and also display some text??

Regards,
Brian

[Juan Manuel Alvarez]

Then I need to make sure such options are passed to the report AFTER the template is loaded, so they overwite them

[Juan Manuel Alvarez]

Fixed in this version http://fdvs.com.ar/djmaven2/ar/com/fdvs/DynamicJasper/3.0.11-beta4-SNAPSHOT/DynamicJasper-3.0.11-beta4-20090918.034625-1.jar

Note

The following option will be always overwritten by the dynamic report
* number of columns
* When-No-Data behavior
* When-Resource-Missing behavior
* Title start on new page flag (false by default)
* Ignore Pagination flag (false by default)
* Detail Band Split allowed flag (true by default)
* Summary start on new page flag (false by default)

Soon to be GA

djmamana,

I'm now able to see the no data text but the height is very small. I'm unable to insert more than a few lines of text. The page footer, summary etc are removed from a dynamic report and a tempalted report. Seems to be very restricting, is there a way to give the noData band the same flexibility as the Detail etc bands?

Brian

[Brian Swain]

The noDataBand should ahve the similar formatting options as other bands. If the report has a large title section and a page footer and summary section the noData section removes the page footer values and summary section. If you inster more than 4 lines of text into the NoData band the noData band is removed.
