Referencing using binary name

[marcosamba]

Trying to compile a jrxml file I'm having the following exception:

TheÂnestedÂtype org.example.ClassA$ClassB cannot be referencedÂusingÂitsÂbinaryÂname

Class B is a static inner class of Class A and I want to access to a (non static) property of type ClassB present in ClassA using a (non static) getter method:

public ClassA {

private ClassA.ClassB propB;

public ClassA.ClassB getPropB() {
return propB;
}

public static class ClassB {
...
}

}

Why do I get the excpetion? What can I do to avoid it?

Thanks.
Marco.

Hi,

 

What version of JR are you using?

 

Thank you,

Teodor

The last one, well until a few hours ago, 2.0.5.

 

Do you think the brand new version will not have this kind of issue?

 

Thanks,

Marco

Hi,

 

I thought you use an older version because I remember fixing something similar to this in the past.

Can you attach the JRXML file, and maybe some sample classes that you have so we can quickly reproduce the problem?

 

Thank you,

Teodor

I've prepared a basic example because the real case is quite complex.

Consider to use a JRBeanCollectionDataSource as Datasource for the report. The Beans are of type ChildB, you can use IReportBeansFactory as factory class to use in iReport (method getChildB) and the provided jrxml to test.

What I get is the following exception trying to compile the jrxml:

TheÂnestedÂtypeÂorg.example.beans.ChildB$InnerChildÂcannotÂbeÂreferencedÂusingÂitsÂbinaryÂname valueÂ=Â(java.lang.String)(""+((org.example.beans.ChildB$InnerChild)field_inner.getValue()).getDesc());//$JR_EXPR_ID=10$

Thanks,

Try to set the "inner" field type to "org.example.beans.ChildB.InnerChild" (instead of org.example.beans.ChildB$InnerChild).

You got it :)
