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 ,
I suspect that the firs assign is generating an expection and the whole code after it is being skipped.
Why don't you try to wrap that #assign into an <#attempt><#recover> block? Something like this:

 

<#attempt>
  <#assign check_status = rest("/users/id/${user.id}/profiles/avatar/size/profile")>
  <#assign test=check_status.@status/>
<#recover>
  <#assign test = "error"/>
</#attempt>

 

<#if test=="success">
   SUCCESS: ${test}
<#else>
  ERROR: ${test}
</#if>

 

I hope this helps.
