----------------------------------
Summary: Placeholders are not resolved in Simple language while
using resource: prefix
Key: CAMEL-12486
URL: https://issues.apache.org/jira/browse/CAMEL-12486
Project: Camel
Issue Type: Wish
Components: camel-core
Reporter: Jan Bednar
Attachments:
Allow_dynamic_resource_loading_in_simple_language_failing_test.patch
This behavior was found in question
https://stackoverflow.com/questions/50063874/load-camels-body-dynamically-depending-on-header
This is because expression with prefix *resource* is resolved in
LanguageSupport#loadResource before property placeholders are resolved. This is
reasonable, as placeholders are resolved in expression loaded from file. But it
prevents from dynamic resource loading.
It would be nice to allow property resolution in resource in this way
{code:java}
.transform().simple("resource:classpath:${header.myFileName}"){code}
I would expect this behavior:
# Resolve placeholders in expression (now missing)
# Load String from resource as new expression (exists)
# Resolve placeholders in new expression (exists)
I have tried to create patch for *SimpleLanguage*, but I failed. Attaching
patch to *SimpleResourceTest* with expected behavior based on master.
