reactjs - 自动完成问题(Material UI + React + Reagent/ClojureScript)

Question

我在使用 Material UI 时遇到问题 Autocomplete与试剂(ClojureScript)。该元素呈现良好，但是当我尝试单击它时，出现以下异常:

Uncaught TypeError: Cannot read property 'focus' of null
    at handleClick (useAutocomplete.js:938)
    at HTMLUnknownElement.callCallback (react-dom.development.js:189)
    at Object.invokeGuardedCallbackImpl (react-dom.development.js:238)

    at HTMLUnknownElement.callCallback (react-dom.development.js:189)
    at Object.invokeGuardedCallbackImpl (react-dom.development.js:238)

打破 JS 调试器，我看到 inputRef.current为空(这是在 focus 和 removeAttribute 上调用的。(奇怪的是，在文件中设置 inputRef 的唯一地方是通过调用 useRef(null) ，这导致 inputRef.current 为空) .)
在我的代码中，我将 Autocomplete 字段定义如下:

(ns my-product-redacted.views.atoms
  (:require [reagent.core :as r]
            ["@material-ui/lab/Autocomplete" :default Autocomplete]
            ;; other requires
  ))

(def autocomplete-field (r/adapt-react-class Autocomplete))

然后，在一个 React 组件中，它的用法如下:

[a/autocomplete-field {:render-input      (fn [js-params]
                                            (let [clj-params (js->clj js-params)
                                                  params     {:label             label
                                                              :width             width
                                                              :select            select?
                                                              :Input-label-props {:shrink true}
                                                              :Select-props      {:native true}}
                                                  all-params  (into clj-params params)]
                                               (js/console.log (clj->js all-params))
                                               (r/as-element [a/text-field all-params])))
                       :options          (when select? (cons {:value "" :label ""} options))
                       :get-option-label (fn [option] (or (get (js->clj option) "label") ""))
                       :default-value    (when (not select?) value-override)
                       :value            (when select? value)
                       :disabled         disabled?
                       :on-focus         #(re-frame/dispatch [::forms/on-focus path])
                       :on-blur          #(re-frame/dispatch [::forms/on-blur path])
                       :on-change        #(re-frame/dispatch (conj on-change (-> % .-target .-value)))})]

(这里， a/text-field 也以与 a/autocomplete-field 相同的命名空间和类似的方式定义。)
JS 控制台日志(来自 (js/console.log (clj->js params)) 调用)显示 inputProps.ref.current设置为空。然而， InputProps.ref不为空。即便如此，我还是尝试手动关联通过 InputProps.ref 传递的相同函数。至 inputProps.ref.current ，但这并没有什么区别。
我也尝试过 https://github.com/mui-org/material-ui/issues/21245 中建议的解决方法(尽管该问题与格式塔库有关，而不是与试剂有关，但这表明引用转发可能存在问题)。但包装 text-field用 ref 放入一个 div取自 InputProps.ref也没什么区别。
有什么建议？

调用 js->clj在渲染输入 js 参数上打破了它们。
我在我的演示库中放了一个 Material UI 自动完成组件的快速演示 here .
但主要取自官方试剂文档/示例here :

(defn autocomplete-example []
  [:> mui/Grid
   {:item true}
   [:> Autocomplete {:options ["foo" "bar" "foobar"]
                     :style {:width 300}
                     ;; Note that the function parameter is a JS Object!
                     ;; Autocomplete expects the renderInput value to be function
                     ;; returning React elements, not a component!
                     ;; So reactify-component won't work here.
                     :render-input (fn [^js params]
                                     ;; Don't call js->clj because that would recursively
                                     ;; convert all JS objects (e.g. React ref objects)
                                     ;; to Cljs maps, which breaks them, even when converted back to JS.
                                     ;; Best thing is to use r/create-element and
                                     ;; pass the JS params to it.
                                     ;; If necessary, use JS interop to modify params.
                                     (set! (.-variant params) "outlined")
                                     (set! (.-label params) "Autocomplete")
                                     (r/create-element mui/TextField params))}]])
