fix: do not set an empty id in plugin framework resource config - #813
For plugin framework resources, getFrameworkExtendedParameters sets id to "" until the resource exists. If the id attribute is a number (e.g. Int64), "" fails to decode, so Connect fails and Create never runs:
cannot construct tf value from json: AttributeName("id"): error parsing number: EOF
The id is now left unset until there is one. This is the plugin framework counterpart of #789, which only fixes the CLI path.

Walkthrough
The framework parameter builder now omits id when the configured ID function returns an empty string. A new test covers empty and non-empty external names.
Changes: Framework ID parameters
Layer / File(s)
Summary
Conditional ID parameter pkg/controller/external_tfpluginfw.go, pkg/controller/external_tfpluginfw_test.go
The builder adds id only when the configured ID function returns a non-empty string. The test checks that an empty name leaves id absent and that "42" is included as the ID.
Issue 785 reports failures associated with empty or synthetic IDs before refresh. This change addresses the empty-ID condition for framework parameters; the issue also covers general state writes outside this diff.
Merge Risk: Moderate · previous review d506e
Omitting empty IDs fixes the targeted decoding problem, but numeric IDs supplied through an injector can now cause reconciliation to panic during state reconstruction. Make reconstruction type-safe before merging.

Full details: Template Breaking Changes
Explanation
The shared framework connector changes generated controller behavior for empty IDs. It can allow resources with numeric IDs to reach creation where Connect previously failed. Both synchronous and asynchronous generated controllers use this connector. The new test checks a parameter map with a string ID schema, not provider reconciliation.

Use a concrete type for the expected ID.
Could we use a string for the expected ID and check the returned type separately? This preserves the presence and value checks while following the Go type convention. Thanks!
As per coding guidelines: “No any type used throughout codebase - use concrete types or type parameters.”

Add numeric-ID reconciliation coverage.
If numeric-ID decoding or creation fails after the map is built, this test still passes. Could you add a numeric-ID case that exercises Connect and successful Create, including a reconnect with a populated ID? Thank you.

Handle non-string IDs during reconstruction.
If an injector supplies a numeric id and GetIDFn returns "", the value remains in params. A cache miss then panics at id.(string), preventing reconciliation. Could we make the reconstruction check type-safe? Thanks!

When a framework provider returns numeric ID 42 with IdentifierFromProvider, IDAsExternalName rejects it after the remote resource is created. Create then fails without recording the external name. Please support numeric IDs in the external-name path. Thanks.

getFrameworkExtendedParameters always set params["id"] to the Terraform
ID, which is empty until the resource is created. A plugin framework
resource whose id is a number cannot decode "", so every reconcile
failed in Connect before Create could run:
cannot construct tf value from json: AttributeName("id"): error
parsing number: EOF
When there is no ID yet, delete the id from the parameters, including
one set by a TerraformConfigurationInjector or by the identifier setter
(e.g. ParameterAsIdentifier("id") with an empty external name), so the
id is either absent or the Terraform ID. This is the plugin framework
counterpart of crossplane#789.

Reads right to me. On main the id is written whenever the schema has one, so a resource that does not exist yet gets "", which an Int64 id cannot decode; leaving the key out until GetIDFn returns something is the minimal fix and is a no-op for string ids, which decoded "" fine before. Since params["id"] = tfID used to overwrite whatever an injector had put there with "" anyway, dropping the key in that case does not lose anything that was previously kept. Read against head 712b561 on main, not run locally.
For the maintainers: this is the plugin framework twin of #789, which guards the same empty id on the CLI path in EnsureTFState; the two touch different files and compose.
I would approve this; the decision is with the maintainers.
