I had the same issue here and never did get to the bottom of it.  Frustratingly im getting the same problem again while using an if/else block on another section of code.  Any update on this would be very helpful

Hi,

 

I got the same issue. It seems to me that Lithium catch the error before Freemarker does.

 

I want to test if one node of the REST result exists:

<#assign user_ranking = rest("/users/id/${user.id}/ranking").ranking />
<#attempt>
	<#assign user_ranking_image_left = author_ranking.display.left_image.url?replace("http://www.cvous.com", "")?js_string />
<#recover>
	<#assign user_ranking_image_left = "" />
</#attempt>
<#attempt>
	<#assign user_ranking_image_right = author_ranking.display.right_image.url?replace("http://www.cvous.com", "")?js_string />
<#recover>
	<#assign user_ranking_image_right = "" />
</#attempt>

But the "attempt" test will generate a "This widget could not be displayed" for anonymous or non admin members.

I don't even know why it works for admin member.

 

Have a nice day!
