File preview is not working in community with LWC component
Hello Everyone,

I am using an lwc component on which users will upload a file and they can also preview that. For a preview, I am using navigationMixin and navigate the record to standard_namedPage which working fine for internal use but the same method is not working in the community. I am not able to preview the file using that. Today I did some research and get to know standard_namedPage not supported community and for that, I need to use standard_webPage which redirects me to the new tab and I can see my file there but the issue is on that new tab I can see my file as a thumbnail, not the actual file. Can someone guide me on how can I preview files in the community as the original file?

Below is the code that I am using for both internal and external.

 

Internal:

this[NavigationMixin.Navigate]({

type: 'standard__namedPage',

attributes: {

pageName: 'filePreview'

},

state : {

// assigning ContentDocumentId to show the preview of file

selectedRecordId:event.currentTarget.dataset.id

}

})

External:

//Getting content version id to assign the url.

contentVersionId = response;

var baseURL = 'https://'+location.host+'/';

var previewURL = baseURL + 'sfc/servlet.shepherd/version/renditionDownload?rendition=THUMB720BY480&versionId='+contentVersionId;

this[NavigationMixin.Navigate]({

type: 'standard__webPage',

attributes: {

url: previewURL

}

}, false );

Thanks,

Arpit Jain

    @SumitKumar10

    For LWC I didn't get any solution but for Aura component you can show preview on community.

    For You can refer below code:

    Component Code:

    <aura:iteration items="{!v.SignedGADPackage}" var="item" indexVar="index">

    <tr>

    <td width="25%">

    {!item.docName}

    </td>

    <td width="25%">

    <lightning:formattedDateTime value="{!item.generatedDocTime}" year="numeric"

    month="numeric" day="numeric" hour="2-digit" minute="2-digit"

    hour12="true" />

    </td>

    <td width="25%">

    {!item.generatedBy}

    </td>

    <td width="25%">

    <a href="" id="{!item.conDocId}" onclick="{!c.previewFile}">View&nbsp;

    <lightning:icon size="x-small" iconName="action:preview" alternativeText="Preview"

    title="Preview" />

    </a>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

    <a href="javascript:void(0)" id="{!item.conDocId}"

    onclick="{!c.downloadFiles}">Download&nbsp;

    <lightning:icon size="x-small" iconName="action:download" alternativeText="Download"

    title="Download" />

    </a>

    </td>

    </tr>

    </aura:iteration>

    JS Code:

    previewFile: function (component, event, helper) {

    var rec_id = event.currentTarget.id;

    $A.get('e.lightning:openFiles').fire({

    recordIds: [rec_id]

    });

    },

    downloadFiles : function (component, event, helper)

    {

    var documentId = event.currentTarget.id;

    var urlString = window.location.href;

    var baseURL = urlString.substring(0, urlString.indexOf("/s"));

    var urlEvent = $A.get("e.force:navigateToURL");

    urlEvent.setParams({

    "url": baseURL + '/sfc/servlet.shepherd/document/download/' + documentId + '?operationContext=S1'

    });

    urlEvent.fire();

    },

    Please markit as best answer if this helps you.

    Thanks,

    Arpit

Data loader problem
I'm trying to insert new records via data loader but I keep getting an error message saying 'Index 100 out of bounds for length 100' and the upload stops part way through, after some records have successfully uploaded.  Does anyone know what this error means?

    I’d first split the CSV into smaller batches and see if it always dies around the same record. That usually makes it easier to tell if it’s the file/data or Data Loader itself. I’ve also used Skyvia for Salesforce imports when Data Loader was giving me trouble, mostly because I could see the failed records and errors without restarting the whole thing.

Dear Community,

I am new to Lightning experience,i have some knowledge about lightning.i tried to generate the pdf for Account or any standard or custom object.i wrote the some logic the pfd is generated with empty sheet,i want all the fields of the perticular object which is i mentioned.i think i missed some logic in my components/controllers.

can any one suggest where i did mistake and also can tell me how to generate the pdf for perticular object either custom or standard

my code is 

Apex class:

public class DataDisplayController {

    public String PDFData{get;set;}

    

    public DataDisplayController(){

        

        PDFData = '';

    }

    public PageReference downloadPDF(){

        System.PageReference pageRef = new System.PageReference('/apex/PDFGenerator');

        //ensure pdf downloads and is assigned with defined name

        pageRef.getHeaders().put('content-disposition', 'attachment; filename=TestPDF.pdf');

        

        return pageRef;

    }

    }

Component:

<aura:component >

    <aura:attribute name = "sendData" type = "Account"/>

    <lightning:button label = "Download Document" onclick = "{!c.downloadDocument}" />

    

</aura:component>

client-side controller.js

({

 downloadDocument : function(component, event, helper){

  var sendDataProc = component.get("v.sendData");

     "label" : "This is test"

  }; //this is data you want to send for PDF generation

  //invoke vf page js method

  sendDataProc(dataToSend, function(){

              

  });

 }

})

Helper.js

({

    helperMethod : function(component,callbackMethod) {

        var action = component.get("c.download");

        action.setCallback(this,function(response){

            var state = response.getState();

            if(state === "SUCCESS"){

                var generatePdf = reponse.getReturnValue();

            }

            else{

                console.log('unable to generate the pdf');

            }

        });

        $A.enqueueAction(action);

        

    }

})

VF Page:

<apex:page controller="DataDisplayController" showHeader="false">

    <apex:includeLightning />

    

    <apex:form>

        <apex:inputHidden id="hidData" value="{!PDFData}"/>

            var hidData = document.getElementById('{!$Component.hidData}');

            hidData.value = JSON.stringify(data);

            

            //invoke PDF Generation

            jsGeneratePDF();

         

            //invoke callback;

            if(typeof callback == 'function') callback();

        }

        

        

        function loadComponents(){

            console.log("Loading lightning component: DataProcessor");

            

            $Lightning.use("c:LightningPDFGeneratorDemoApp", function() {

                $Lightning.createComponent("c:DataProcessor",

                { 

                    sendData : saveData

                },

                function(cmp) {

                    // do some stuff

How to resize the lightning toggle button in lightning component?
<lightning:buttonMenu alternativeText="Toggle menu" iconSize="x-Small" onselect="{!c.handleMenuSelect}">

    In my case I used empty attributes for active and inactive toggle as these were unwanted. It reduced the height

    <lightning-input

       type="toggle"

       label="All"

       message-toggle-active=""

       message-toggle-inactive="">

     </lightning-input>

    Hi Sachin,

    Greetings to you!

    You cannot use the Developer Console to develop LWC. To experiment with Lightning Web Components, you can use the Lightning Web Components Playground: https://developer.salesforce.com/docs/component-library/tools/playground

    But there are some limitations:

    1. The playground doesn't provide Security with Lightning Locker.

    2. The playground can’t access Salesforce organizations, so it doesn’t support features that require data from Salesforce.

    https://developer.salesforce.com/docs/component-library/documentation/lwc/install_playground

    As per doc: https://developer.salesforce.com/blogs/2018/12/developer-tools-for-lightning-web-components.html

    There are other IDE as well for developing Lightning Web Component like Illuminated Cloud (https://plugins.jetbrains.com/plugin/10253-illuminated-cloud-2) but Salesforce recommends Visual Studio Code and the Salesforce Lightning Web Components Extension for VS Code. This combination provides powerful connections to the Salesforce CLI from within VS Code, plus additional features specific to developing Lightning web components for Salesforce.

    I hope it helps you.

    Kindly let me know if it helps you and close your query by marking it as solved so that it can help others in the future. It will help to keep this community clean.

    Thanks and Regards,

    Khan Anas

    I don't know if anyone has found solution for this or not, only way to do this is open the Lightning messaging channel in VS code, right click from directory and select "Delete from project and org"

Approval Processes Error : Lightning Community : Another user recalled or responded to this request.
I have a requirement wherein I need to send a quote record for approval using Salesforce standard approval process. I've maintained approver user in a custom field(user lookup) on my record. When I click on 'Submit for approval' from Sales portal it gets submitted successfully.

Problem : When I try to submit the 'same' record with a partner user from community portal, I get this error "another user recalled or responded to this request." 

Things that I have already tried:

1. Check if Approval process is active.

2. Check if Approver is active.

3. Create a fresh new record which is not submitted for approval yet. (Did not work for this either, No it was not already approved).

4. Logged in with the approver to check if he/she is able to access the quote record 'Read-Write'. (no sharing problem)

5. When I login as my user (Admin) to community and submit the record, Then I'm able to submit. (So, this cannot be community limitation either).

What am I missing??

Can anyone please help me here?

Thanks,

Priyal

    Thanks for the direction,  Gustavo Silva . I checked your post, but still spent two days finding a solution! 

     

    For me, the Process Automation Settings for "Automated Process User Email Address" was still pointing to an old "No Reply" ID. When the org-wide address was removed/updated, it should have auto-updated to show or point to the latest one. That was my issue. 

     

    The case is now with Salesforce, and I'm hoping they can help by making the latest address available in the dropdown list — hopefully they can get this fixed.
