According to the documentation here in order to retrieve a list of picklist values for an object we need to pass in a Record Type Id which can be retrieved using the getObjectInfo method.

The issue is that these are both wire functions and I cannot figure out how to chain these methods.

If I try code like the following:

getObjectInfo({ objectApiName: ACCOUNT_OBJECT })

            .then(result => {

                return getPicklistValues({recordTypeId: result.defaultRecordTypeId, fieldApiName: TYPE_FIELD});

            })

            .then(result => {

                this.picklistValues = result.data

            })

            .catch(error => {

                this.error = error;

            });

I get an error

render threw an error in 'c:getpicklistexample' [Imperative use is not
supported. Use @wire(getObjectInfo).]

If I try something like

@track rtId;



    @wire(getObjectInfo, { objectApiName: ACCOUNT_OBJECT })

    handleResult({error, data}) {

        if(data) {

            this.rtId = data.defaultRecordTypeId;

        }

    }



    @wire(getPicklistValues, {recordTypeId: this.rtId,fieldApiName: TYPE_FIELD})

    picklistValues;

Then it throws an internal server error. Anybody have an idea as to how I could retrieve the record type Id and then call to get the pick list values like the documentation suggests?

FYI my imports are:

import { LightningElement, wire, track } from 'lwc';

import { getPicklistValues, getObjectInfo } from 'lightning/uiObjectInfoApi';

import TYPE_FIELD from '@salesforce/schema/Account.Type';

import ACCOUNT_OBJECT from '@salesforce/schema/Account';

You have to use dynamic binding:

@wire(getPicklistValues, {recordTypeId: "$rtId", fieldApiName: TYPE_FIELD})

picklistValues;

This is mentioned in Use the Wire Service to Get Data.

I wrote a mockup that demonstrates this. You should be able to copy-paste this code directly.

<template>

    <template if:true={hasPicklistValues}>

        <select>

            <template for:each={picklistValues.data.values} for:item="entry">

                <option key={entry.value} value={entry.label}>{entry.label}</option>

            </template>

        </select>

    </template>

</template>

import { LightningElement, wire, track } from 'lwc';

import { getPicklistValues, getObjectInfo } from 'lightning/uiObjectInfoApi';

import TYPE_FIELD from '@salesforce/schema/Account.Type';

import ACCOUNT_OBJECT from '@salesforce/schema/Account';





export default class Democomponent extends LightningElement {

    @track rtId;

    @track error;



    @wire(getObjectInfo, { objectApiName: ACCOUNT_OBJECT })

    handleResult({error, data}) {

        if(data) {

            this.rtId = data.defaultRecordTypeId;

        } else {

            this.error = error;

        }

    }



    @wire(getPicklistValues, {recordTypeId: "$rtId", fieldApiName: TYPE_FIELD})

    picklistValues;



    get hasPicklistValues() {

        return this.picklistValues && this.picklistValues.data && this.picklistValues.data.values;

    }

}
