widget could not be displayed (custom widget)

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 ...

    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

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
