Hi, all! We have a custom component, and when the user is logged out, we see a "This widget could not be displayed." message. I checked with Support and they said to make sure <#if !user.anonymous && (tkbBoards.board?size-1>0)> is in the code before the API call. Any idea on what else might be wrong? I'd appreciate any help!

Hi @jchen, Sorry, my bad ... typo there ... it should be this (without the "/" in the back of first line) <#if !user.anonymous>... rest of code ...</#if> (Just FYI, the error description said line 1, column 22 ... that means a typo on the first line, 22nd character) Let us know if that works out for you

widget could not be displayed (custom widget)

Hello there,
Actually i faced this problem many many times, but at the end i found that there's no error in the code, there's no error at all, this error caused by a permissions limitation! all you have to do is changing the permissions in the "Admin" tab, and then everything should go as you expected.

I've gotten that error a number of times if there's some type of freemarker error in your code. Most of the time you get the crazy yellow/red long error message but not always. Maybe go through your code line/block by line/block and comment in/out things as you go through in order to test what will print out to the page without error?

hi jchen

Are you very certain that the <#if !user.anonymous> check is before any REST API call?

Typically, you get "widget could not be displayed" if there's a template exception. For instance, you're making a REST API as an anonymous user and your permission settings does not allow.

Hence, i concur with Support feedback, you need to put the <#if !user.anonymous> check prior to the REST API call

But i'm a little intrigue with your check - tkbBoards.board?size because that seems indicate that you're REST API call and assigning to variable tkbBoards.

Look out for statements like this:

<#assign tkbBoards = rest("/xxxx/...") />

If you do see this line, you need to put <#if !user.anonymous> prior to this line.

(not exactly sure what your code does but you should probably separate this <#if tkbBoards.boards?size check till after the REST API call?)

Hope that helps

Can you please post your code here, not the entire code, but just a snippet where you have used this condition. This usually is the case when the users don't have the permissions to make the API calls, other than that, I will need to have a look at your code.

  Here's the beginning of my code
  <#assign tkbBoards = rest("/categories/id/demandforce-tkb/boards/nested?restapi.response_style=view").boards/> <#if !user.anonymous && (tkbBoards.board?size-1>0)> <#assign boardIdList=[] /> <#list tkbBoards.board as board> <#assign boardId = board.id/> <#assign boardIdList = boardIdList + [boardId] /> </#list>
  I tried adding <#if !user.anonymous && (tkbBoards.board?size-1>0)> before the first line and got this
  Freemarker template 'preview' parsing failed:
  ParseException:Parsing error in template "preview" in line 55, column 16: Unclosed #if when the end of the file was reached.

    Hi jchen ,
    
    since you have put
    
    <#if !user.anonymous && (tkbBoards.board?size-1>0)>
    
    on the top of your code, you may have to put
    
    </#if>
    
    to the end of the code.
