Casting in Qute?

[GregJohnStewart]

I have a pojo that can be one of several sub-classes. This pojo is held in another object, which holds the superclass form. Qute seems to preemptively be judging that the object doesn't have the method:

{#when result.getCheckedOutFor().getType()}
{#is OQM_ENTITY} {! I use type flags to specify sub-types, for Jackson !}
{#interactingEntityRef entityRef=result.getCheckedOutFor().getEntity()}{/interactingEntityRef}
{#is EXT_SYS_USER}
{result.getCheckedOutFor().getName()}
{/when}

This produces:

- {result.getCheckedOutFor().getEntity()}: Property/method [getEntity()] not found on class [tech.ebp.oqm.lib.core.object.storage.checkout.checkoutFor.@NonNull CheckoutFor] 

(CheckoutFor is my super class, held in result)

Is there an easy way to deal with polymorphism in Qute? Casting in the typical sense doesn't work here. Also tried instanceof in an if statement, same error.

Ok, so this is a build time validation error. We don't know the runtime type of the object returned from the getCheckedOutFor() method at this time. You can try to exclude this particular method from validation by means of quarkus.qute.type-check-excludes=org.acme.CheckoutFor.getEntity. It should resolve just fine at runtime.

Thanks, that works! I realize this is a hard thing to solve, but this resolution isn't amazing, as we are circumventing checks.

Maybe have a way for #let to cast?
