Description

I have an immutable class that shares naming for a field and a static getter:

package org.dempsay.demo.freemaker.api;

 

 

public class Sample {
    public final String data;
    protected Sample(final SampleBuilder builder) {
        this.data = builder.data;
    }
    public static String data(final Sample sample) {
        return sample.data;
    }
}

 

When I render it with the following template:

The data from this sample is ${sample.data}

I get this error:

Feb 17, 2018 7:59:40 AM freemarker.log._JULLoggerFactory$JULLogger error

SEVERE: Error executing FreeMarker template

FreeMarker template error:

For "${...}" content: Expected a string or something automatically convertible to string (number, date or boolean), or "template output" , but this has evaluated to a method+sequence (wrapper: f.e.b.SimpleMethodModel):

==> sample.data  [in template "sample.ftl" at line 1, column 32]

Tip: Maybe using obj.something(params) instead of obj.something will yield the desired value

FTL stack trace ("~" means nesting-related):
