Output text is changed(Thymeleaf3)

[yKazihara]

After I upgraded from 2 to 3, output text is changed.

public class Page {
  public String code;
}

public class SampleAction {
  ...
  Page page = new Page();
  page.code = "APPLE";
  ...
}

<span th:text="${it.code}">ORANGE</span>

・Thymeleaf 2.1.4.RELEASE
　APPLE // OK

・Thymeleaf 3.0.2.RELEASE
　701259 // hashCode?

Could you tell me why the output is changed?

[danielfernandez]

Nothing should have changed in your case. Are you completely sure that your expression in the second case includes the .code part?

Also, what is the environment? Are you using thymeleaf in a Spring app?

I don't use thymeleaf in a Spring app.

I wrote another sample.
This Junit test was successful.

import static org.hamcrest.CoreMatchers.*;
import static org.hamcrest.MatcherAssert.*;

import org.junit.Test;
import org.thymeleaf.TemplateEngine;
import org.thymeleaf.context.Context;

public class Sample {

  public static class Page {
    public String name = "orange";
    public String code = "apple";
  }

  @Test
  public void test() {
    TemplateEngine engine = new TemplateEngine();

    Page page = new Page();
    Context context = new Context();
    context.setVariable("p", page);

    assertThat(engine.process("[[${p.name}]]", context), is("orange"));

    assertThat(engine.process("[[${p.code}]]", context), is(not("apple")));
    assertThat(engine.process("[[${p.code}]]", context),
        is(Integer.toString(page.hashCode())));
  }
}

This is actually a bug in the OGNL expression language. OGNL is the expression language being used by Thymeleaf in non-Spring applications. See orphan-oss/ognl#32

I'm leaving this open in order to update Thymeleaf's dependency to a future version of OGNL that might fix this.

[danielfernandez]

OGNL 3.1.12 released and Thymeleaf's 3.0 branch updated to use it.

Already in 3.0.3-SNAPSHOT
