theme.register is not a function

[mvysny]

Using vcf-progress-spinner in a simple Vaadin project makes the javascript throw an exception when built in production mode:

Uncaught TypeError: theme.register is not a function
    <anonymous> http://localhost:8080/VAADIN/build/vaadin-bundle-2be600b9349182885bea.cache.js:34470

The stacktrace points to the following deobfuscated webpack code:

/***/ }),
/* 187 */,
/* 188 */
/***/ (function(module, exports) {

var theme = document.createElement('dom-module');
theme.id = 'vcf-progress-spinner-lumo';
theme.setAttribute('theme-for', 'vcf-progress-spinner');
theme.innerHTML = `
    <template>
      <style>
        :host {}
      </style>
    </template>
  `;
theme.register(theme.id);

Looks like a polymer import is missing.

I have updated this codebase and used the latest vcf-element template. In the process I removed the unnecessary style module that was causing the error reported here. @mvysny could you test with v1.1.0 and confirm that this issue is resolved?

[mvysny]

Using v1.1.0 is working for me, thanks! 👍

This code works for me, while failing previously:

@Route("")
@PWA(name = "Project Base for Vaadin", shortName = "Project Base")
class MainView : KComposite() {
    private val root = ui {
        verticalLayout {
            add(VcfProgressSpinner())
        }
    }
}

@NpmPackage(value = "@vaadin-component-factory/vcf-progress-spinner", version = "1.1.0")
@JsModule("@vaadin-component-factory/vcf-progress-spinner")
@Tag("vcf-progress-spinner")
class VcfProgressSpinner : Component()
