JasperReportsMultiFormatView cascade exporterParameters?

[Maulisho]

Hi,

I started using Jasperreports with spring yesterday and I want to make a report available in different formats, hence my use for JasperReportsMultiFormatView. I want to use the exporterParameters, but the MultiFormatView does not set the exporterParameters on the views it creates as I expected. Am I missing a point here? Or is this just a missing feature?

Another minor problem I found (I must say I didnt look into it very deeply), but the getExporterParameters method is protected and I think that causes the below expection while filling the property through .properties file by for instance a ResourceBundleViewResolver. Using an XmlViewResolver fixes the problem (prolly cause that just feeds the Map all at once to the setter method without calling a getter method first?)

Any thoughts on these issues?

Thanx,

Maulisho,

I'll raise an issue in JIRA for these bugs and try to get the fixes in for 1.2

Rob,

Thanx.

I wrote some code to circumvent the exportparameters not cascading issue. Nothing fancy, but overriding the setExporterMappings() to not do the fancy map conversion, but just simply store the original Map and then calling setExporterMappings on the created views should be enough. I think this will also fix the other problem (cause then the getter returns the same kind of map the setter inserted). So you might wanna think about moving the map conversion to some other place.

Alot of the properties in AbstractJasperReportsView are private though (including exporterParameters). So you would have to fiddle with that a bit.

Fixes for both issues have been committed to CVS.

I'm trying to turn off "is_using_images_to_align" as well, and I'm getting the same error as noted above (with Spring 1.2.3).

Here's what I have in my views.properties file.

reportView.exporterParameters.net.sf.jasperreports .engine.export.JRHtmlExporterParameter.IS_USING_IM AGES_TO_ALIGN=false

I've tried using the following as well, but no luck.

reportView.exporterParameters[net.sf.jasperreports.engine.export.JRHtmlExporterP arameter.IS_USING_IMAGES_TO_ALIGN]=false

What's the syntax for setting exporterParameters?

[robh]

Matt,

I plead ignorance here - I haven't been configuring my JasperReports using the properties syntax. Rather I have been using BeanNameUrlResolver and configuring using XML syntax. Can you raise a JIRA issue for this and I'll figure out what the situation is with the properties syntax.

Rob

[mraible]

I'm more than happy to enter an issue for this, but I'm not sure it's a bug. From looking at some tests, it seems like you should be able to set a maps keys and values using:

propertyName[keyName]=keyValue

If that's the property syntax, then it might be a bug - but I don't want to jump to that conclusion until I'm sure my syntax is correct.

[robh]

I agree - I don't think this is a bug, because it works when using the <map>. However, I am not really certain of the properties syntax. I have a few issues related to Jasper for 1.3 anyway so I'll look into this at the same time.

This is a bug - SPR-1198 (http://opensource.atlassian.com/projects/spring/browse/SPR-1198). I'll fix this for the 1.2.4 release.
