Claus Ibsen created CAMEL-6674:
----------------------------------
Summary: Add allowNull option to @Converter to allow type
converters to return null as valid response for special use-cases
Key: CAMEL-6674
URL: https://issues.apache.org/jira/browse/CAMEL-6674
Project: Camel
Issue Type: Improvement
Components: camel-core
Affects Versions: 2.11.1, 2.12.0
Reporter: Claus Ibsen
Assignee: Claus Ibsen
Fix For: 2.11.2, 2.12.1
See nabble
http://camel.465427.n5.nabble.com/Xpath-parameter-binding-NodeList-vs-Node-tp5738067.html
This avoids the situation with the NodeList -> Node converter that may return
null the 1st time, and then its regarded as a misses for conversion in future
attempts.
Just be annotation the method from
@Converter
to:
@Converter(allowNull = true)
Should allow to fix this. As then the type converter registry knows that a null
response is valid.
