HarmonyOS 鸿蒙Next form Kit服务卡片，EntryFormAbility使用PersistentStorage和AppStorage不生效

Form Kit服务卡片，EntryFormAbility使用PersistentStorage和AppStorage不生效

1. 想把所有加桌的formId缓存起来(鸿蒙SDK未提供获取目标应用所有formId的方法，只能开发者自己缓存)
2. 在EntryFormAbility里的onAddForm方法中AppStorage.set缓存，onRemoveForm方法里delete
3. 在利用PersistentStorage持久化
4. 在EntryAbility的里AppStorage.get 获取缓存，发现读取不到
5. 可以用db实现，但是存几个formId用db感觉有点复杂

请问EntryFormAbility是不是不支持与EntryAbility通过 PersistentStorage和AppStorage 共享数据？

import { formBindingData, FormExtensionAbility, formInfo } from ‘[@kit](/user/kit).FormKit’;
import { Want } from ‘[@kit](/user/kit).AbilityKit’;
import { JSON } from ‘[@kit](/user/kit).ArkTS’;
import { hilog } from ‘[@kit](/user/kit).PerformanceAnalysisKit’;

PersistentStorage.persistProp(‘WidgetCardFormIdSet’, new Set<string>([]));


export default class EntryFormAbility extends FormExtensionAbility {
onAddForm(want: Want) {
hilog.info(0x0000, ‘EntryFormAbility’, ‘onAddForm WidgetCardFormIdSet Size: %{public}s’,
AppStorage.get<Set<string>>(‘WidgetCardFormIdSet’)?.size);


let formId = want?.parameters?.[formInfo.FormParam.IDENTITY_KEY] as string
AppStorage.set(‘WidgetCardFormIdSet’, AppStorage.get<Set<string>>(‘WidgetCardFormIdSet’)?.add(formId))
let formData = ‘’;
return formBindingData.createFormBindingData(formData);
}


onCastToNormalForm(formId: string) {
hilog.info(0x0000, ‘EntryFormAbility’, ‘onCastToNormalForm formId: %{public}s’, formId);
// Called when the form provider is notified that a temporary form is successfully
// converted to a normal form.
}


onUpdateForm(formId: string) {
hilog.info(0x0000, ‘EntryFormAbility’, ‘onUpdateForm formId: %{public}s’, formId);
// Called to notify the form provider to update a specified form.
}


onFormEvent(formId: string, message: string) {
hilog.info(0x0000, ‘EntryFormAbility’, ‘onFormEvent formId: %{public}s’, formId);
// Called when a specified message event defined by the form provider is triggered.
}


onRemoveForm(formId: string) {
hilog.info(0x0000, ‘EntryFormAbility’, ‘onRemoveForm formId: %{public}s’, formId);
AppStorage.set(‘WidgetCardFormIdSet’, AppStorage.get<Set<string>>(‘WidgetCardFormIdSet’)?.delete(formId))
// Called to notify the form provider that a specified form has been destroyed.
}


onAcquireFormState(want: Want) {
hilog.info(0x0000, ‘EntryFormAbility’, ‘onAcquireFormState Want: %{public}s’, JSON.stringify(want));
// Called to return a {[@link](/user/link) FormState} object.
return formInfo.FormState.READY;
}
}
