---------------------------------------
Summary: Can't access nio Path.getParent() in templates
Key: FREEMARKER-145
URL: https://issues.apache.org/jira/browse/FREEMARKER-145
Project: Apache Freemarker
Issue Type: Bug
Components: engine
Affects Versions: 2.3.30
Reporter: Alfio Gloria
When using something like ${data.path.parent} freemarker throws an exception
"The following has evaluated to null or missing" (obviously on a path that has
non null parent).
After some investigation i figured out that freemarker does not recognize
getParent() as a valid bean method.
This seems due to a condition in ClassIntrospector, line 827:
if (am.getReturnType() == m.getReturnType())
where
am.getReturnType() -> java.nio.file.Path
m.getReturnType() -> sun.nio.fs.UnixPath
I don't know the rationale of the aforementioned condition but it seems weird
to me that I can reference a Path object with ${data.path} but not with
${data.path.parent}
