Qute: Incorrect behaviour with complex expressions

[kucharzyk]

Describe the bug

I've created bean Validation for validation purposes

@RequestScoped
@Named("Validation")
public class Validation {

    public boolean hasViolations(String field) {
       // implementation details
    }

    public List<String> getViolations(String field) {
       // implementation details
    }
}

I've tried to use method getViolations in my tag

{@java.lang.String field}
{#if inject:Validation.hasViolations(field)}
    <div class="mb-3 alert alert-danger d-flex align-items-center" role="alert">
        <svg class="bi flex-shrink-0 me-2" width="24" height="24" role="img" aria-label="Danger:">
            <use xlink:href="#exclamation-triangle-fill"/>
        </svg>
        {#each inject:Validation.getViolations(field)}
        <div>{it}</div>
        {/each}
    </div>
{/if}

And I've got the following exception:

io.quarkus.qute.TemplateException: Found template problems (1):
[1] Incorrect expression found: {field}
        - Unsupported iterable type found: java.lang.String
        - at tags/validation.html:8

It works only with small workaround (define local variable using let)

{@java.lang.String field}
{#if inject:Validation.hasViolations(field)}
    <div class="mb-3 alert alert-danger d-flex align-items-center" role="alert">
        <svg class="bi flex-shrink-0 me-2" width="24" height="24" role="img" aria-label="Danger:">
            <use xlink:href="#exclamation-triangle-fill"/>
        </svg>
        {#let violations=inject:Validation.getViolations(field)}
        {#each violations}
        <div>{it}</div>
        {/each}
        {/let}
    </div>
{/if}
