> NPE when no title using primefaces mobile
> -----------------------------------------
>
> Key: MYFACES-3708
> URL: https://issues.apache.org/jira/browse/MYFACES-3708
> Project: MyFaces Core
> Issue Type: Bug
> Affects Versions: 2.1.10
> Environment: primefaces 3.5, primefaces mobile 0.93, OWB 1.1.7, Tomcat 7
> Reporter: Karl Kildén
>
> Primefaces mobile pages are described with pm:page and you can set title="your title".
> I don't want a title so I left the attribute out but that caused NPE.
> HtmlResponseWriterImpl
> 1018 if (str.length() > 0)
> The string in that case is null hence the length check causes NPE. Not sure if str != null should be added or not , maybe primefaces is doing something bad.
> Workaround is to use title="" but it's not very pretty.
