Not sure if that helps or not.
I think you're correct, the string is null, hence the error.
Maybe rather than using ?has_content, try the below:
Checks if the attribute of the object is null:
<#if object.attribute??></#if>
Checks if object or attribute is null:
<#if (object.attribute)??></#if>
Hope this helps !
- @olivier thats the case iam also assuming. Some time subject comes null that's why exception is coming. But iam not sure how to stop that null value or make such condition that it shouldn't show exception.
Have you tried
<#function truncateMaybe string, append = '...'>
<#if (string.attribute)??>
<#if ( string?length < 30 ) >
<#return string>
<#else>
<#return string?substring( 0, 30 ) + append>
</#if>
</#if>
</#function>You can probably combine the two conditions in one if statement ...
I'm not a freemarker expert, this is just a guess ...
- @olivier yes. I did try that but its not working to me
