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

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.

    hi jchen,

    i see two issues.

     

    Issue 1: no closing #if

    for this message:

    Unclosed #if when the end of the file was reached.

    you need to put the closing </#if> at the bottom on the page

     

    Issue 2: check for tkbBoards cannot be done before the var assignment

    Try something like this:

    - check if user is not anonymous before making the REST api call 

    - check the tkbBoards size only after the REST api call

    - after the rest of the code remember to put the closing </#if> (and you need 2 now as there's 2 #if)

    <#if !user.anonymous />
<#assign tkbBoards = rest("/categories/id/demandforce-tkb/boards/nested?restapi.response_style=view").boards/>

<#if (tkbBoards.board?size-1>0)>
<#assign boardIdList=[] />
<#list tkbBoards.board as board>
	<#assign boardId = board.id/>
	<#assign boardIdList = boardIdList + [boardId] />
</#list>

... rest of the code here ...

</#if>
</#if>

      Thank you guys for your suggestions! JasonL , I did as you suggested but get this error
