widget could not be displayed (custom widget)

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

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

 Not sure what that means...any ideas? Sorry about all the questions, I'm fairly new at this!

That worked! JasonL , you are my hero :smileyvery-happy: THANK YOU!!!

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.
