Freemarker If/else not working, strange.

Hi Gursimrat,
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.

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}"> ${user.login}</a></p>
						<#if pvt_msg_count.value?number &gt; 0>
						<p class="settings-links"><a href="/t5/user/myprofilepage/tab/personal-profile">SETTINGS</a><a href="/t5/notes/privatenotespage" title="${pvt_msg_count.value} Unread Messages"><span class="unread-pvt-msg">MESSAGES</a><a href="/t5/help/faqpage">HELP</a><a href="${webUi.getUserLogoutPageUrl("/")}">SIGN OUT</a></p>
						<#else>
						<p class="settings-links"><a href="/t5/user/myprofilepage/tab/personal-profile">SETTINGS</a><a href="/t5/notes/privatenotespage" title="No Unread Messages">MESSAGES</a><a href="/t5/help/faqpage">HELP</a><a href="${webUi.getUserLogoutPageUrl("/")}">SIGN OUT</a></p>
						</#if>
						</div>
				</div>
			<#else>
				
No Avatar Text Should be displayed

		</#if>

	<#else>		
<!-- If user is Not logged in-->
	<div id="buttonCol" class="signupCol clearfix">
			<div class="link-btn black-btn -btn">
				<@component id="users.action.login" />
			</div>

			<div class="link-btn blue-btn -btn">
				<@component id="users.action.registration" />	
			</div>
			
		</div>



		
</#if>

Hi Gursimrat 

the "Widget could not be displayed" text is used to mask the full stack trace (so that it is more user friendly) - if you need to know the precise exception you can always ask support to look for that in your logs.

I suspect the problem may be that in some scenarios the check_status variable may not be initialized correctly. Have you tried setting it to a value (such as an empty string) in the recover block, and then check for that before checking the status attribute?

Thanks,

Paolo

The problem is.. if you set check_status to "" the <#if check_status.@status == "success"> will fail because now check_status is not an XML node anymore but a string, which cannot reference the @status attribute and this would lead to an error.
That's why, IMHO, you should try and set another status variable in the <#attempt> statement and test on it.

Below is the exception that is getting printed, I am unable to figure it why it is giving error, any help?

The following has evaluated to null or missing:
==> check_status  [in template "preview" at line 108, column 22]

Tip: If the failing expression is known to be legally null/missing, either specify a default value with myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthessis: (myOptionVar.foo)!myDefault, (myOptionVar.foo)??

The failing instruction (FTL stack trace):
----------
==> #if check_status.@status??  [in template "preview" at line 108, column 17]
    #if user.registered  [in template "preview" at line 101, column 1]
----------

Following code has worked, but strangely, if the user for which i am checking is not an admin, it always shows widget could not be displayed.

If I assign Admin role to him, this works fine, even if I make rest calls as 

<#assign xyz= restadmin("dummy_rest_url")>

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