I try to figure out how to get a Bundle Template inheritation/override with Symfony.

I am aware about the Documentation: https://symfony.com/doc/current/bundles/override.html#override-templates

Thats´s so far clear and works as expected.

But, i create a own Bundle which inherits as Dependency another Bundle with the goal to extend this.

Bundle A: Toolbox Bundle (Templates located in the Bundle in “templates” Folder and has config as well)

Bundle B: My own Bootstrap Bundle (Templates located in the Bundle in “templates” Folder)

what i do is this:

class BootstrapBundle extends AbstractBundle implements PimcoreBundleInterface, DependentBundleInterface
{
...
    public function loadExtension(array $config, ContainerConfigurator $container, ContainerBuilder $builder): void
    {
        $container->import('../config/services.yaml');
    }

    public static function registerDependentBundles(BundleCollection $collection): void
    {
        $collection->addBundle(new ToolboxBundle);
    }

    public function prependExtension(ContainerConfigurator $container, ContainerBuilder $builder): void
    {
        // prepend config from a file
        $container->import('../config/packages/toolbox.yaml');
    }

...
}

Then i use my “Bootstrap” Bundle within my own Project, and – damn – it ignore the “templates” folder within my own Bundle. Only in my project files if i create a folder for override Templates it works, but it only “overrides” the original Template Path Parts.

My expectation was that Templates will we search in this order:

{current_project_dir}/templates/bundles/BootstrapBundle/...
{current_project_dir}/templates/bundles/ToolboxBundle/...
{vendor_bootstrap_bundle_dir}/templates/bundles/ToolboxBundle/...
{vendor_toolbox_bundle_dir}/templates/...

But it only searches:

{current_project_dir}/templates/bundles/ToolboxBundle/...
{vendor_toolbox_bundle_dir}/templates/...

Looks i made something wrong within my Bundle or it isn´t possible to achive such a inerhitation from Bundle Templates
