--------------------------------
Fix Version/s: 4.14.3
> Freemarker shared variables not respected when using dynamic templates
> ----------------------------------------------------------------------
>
> Key: CAMEL-22772
> URL: https://issues.apache.org/jira/browse/CAMEL-22772
> Project: Camel
> Issue Type: Bug
> Components: camel-freemarker
> Affects Versions: 4.16.0
> Reporter: Bartosz Popiela
> Priority: Minor
> Fix For: 4.14.3, 4.17.0
>
>
> I have a ComponentCustomizer which provides a custom Freemarker method:
> {code:java}
> @BindToRegistry(lazy=true)
> public ComponentCustomizer freemarkerCustomizer(@BeanInject CacheService
> cacheService) {
> return new ComponentCustomizer() {
> private final BeansWrapper beansWrapper =
> new
> BeansWrapperBuilder(freemarker.template.Configuration.DEFAULT_INCOMPATIBLE_IMPROVEMENTS).build();
> @Override
> public void configure(String name, Component component) {
> try {
> configure((FreemarkerComponent) component);
> } catch (TemplateModelException e) {
> throw new RuntimeException(e);
> }
> }
> private void configure(FreemarkerComponent component) throws
> TemplateModelException {
> var configuration = component.getConfiguration();
> configuration.setRecognizeStandardFileExtensions(true);
>
> configuration.setRegisteredCustomOutputFormats(List.of(SafeJsonOutputFormat.INSTANCE));
> configuration.setSharedVariable("customMethod", new
> MyCustomMethod());
> component.setConfiguration(configuration); // This is necessary
> because FreemarkerComponent#getConfiguration returns a cloned object
> }
> @Override
> public boolean isEnabled(String name, Component target) {
> return target instanceof FreemarkerComponent;
> }
> };
> } {code}
> When passing a template with the CamelFreemarkerTemplate header,
> FreemarkerEndpoint creates a new freemarker.template.Configuration which
> doesn't provide my customMethod.
