Head Contribution error with boolean

[Ergun Polat]

Hi, 

For some reason when my boolean result returns false, which is part of my head contribution tag, I am getting an error 

Here is my tag

18 <@hst.headContribution category="htmlHead" >
19    <#if document.rocketlawyerfr_seometadata.selection_booleanradiogroup>
20       <meta name="robots" content="noindex, nofollow" />
21     </#if>
22 </@hst.headContribution>

When the  document.rocketlawyerfr_seometadata.selection_booleanradiogroup is false it returns the following error 

[INFO] [talledLocalContainer] [Fatal Error] :1:1: Premature end of file.
[WARNING] [talledLocalContainer] 14:46:05 WARN  [HstFreemarkerServlet] Error while invoking the "headContribution" JSP custom tag; see cause exception

[INFO] [talledLocalContainer] ----. To see the stack trace, set 'org.hippoecm.hst.servlet.HstFreemarkerServlet' log-level to debug in log4j configuration or runtime via the logging servlet

Not sure why this is failing, If anyone can help that would that be great. Thanks

Hi,

If you wrap hst.headContribution tag by #if instead of the other way around, it will work.

hst.headContribution needs to parse the markup inside itself. In your case, it failed to parse the empty string in case of false.

HTH,

Woonsan
