Freemarker If/else not working, strange.

I am not able to handle the exception here   Below is the response XML which is giving the error:   <response status="error"> <error code="503"> <message>An object in the path is null.</message> ...

    I'm a little late to the party, but thought I'd share a work-around I've used in the past for this situation. In the code below, I check first to see whether the user has an avatar. I do this by seeing if the object returned via the REST API is not null. If it's not null (there's an image), then I make an additional REST API call to get the avatar in the desired size.

     

    <#attempt>
  <#assign avatarObj = restadmin("/users/id/${user.id?c}/profiles/avatar").image />
  <#if !((avatarObj.@null[0])?? && avatarObj.@null=="true") >
    <#assign avatar = restadmin("/users/id/${user.id?c}/profiles/avatar/size/profile").image />
  </#if>
<#recover>
</#attempt> 

${avatar.url!""}

     I hope this helps!

Hi Nico nathan 

 

Below is my actual excerpt from the code which is giving issues. When the returned status is not success, it shoud print the text No Avatar Text Should be displayed on the screen, but instead, it shows Widget Could no be displayed 2 times. It is working fine for Success case.

 

 

 

<!-- If user is logged in-->
<#if user.registered == true>


<#attempt>
	<#assign check_status = rest("/users/id/${user.id}/profiles/avatar/size/profile")>
<#recover>
	<!-- Just checking the status of the REST call in the Attempt block -->
</#attempt>
	
		<#if check_status.@status = "success">
	           
				<#assign user_avatar = rest("/users/id/${user.id}/profiles/avatar/size/profile").image>
				<#assign user_profile = rest("/users/id/${user.id}?restapi.response_style=view").user>
				<div class="avatar-mash-area">
					<img src="${user_avatar.url}" alt="${user.login}" title="${user.login}" height="64" width="64"/>
					<#assign pvt_msg_count = rest("/users/id/${user.id}/mailbox/notes/inbox/unread/count")>	
						<div class="avatar-links-mash">
				
						<p>Hello, <a href="${user_profile.@view_href}" title="${user.login}"> ${user.login}</a></p>
