Tiles 2.x: TilesConfigurer NPE when no definitions found [SPR-12362]

[spring-projects-issues]

Arnaud Kleinveld opened SPR-12362 and commented

We had two lines in the webmvc-config.xml for the TilesConfigurer

<value>/WEB-INF/views/**/views.xml</value>
<value>/WEB-INF/flows/**/views.xml</value>

Then when we removed the last views.xml under the /WEB-INF/flows tree the application crashes at startup with an NPE caused by line 423 of the TilesConfigurer. See error-report with stack-trace attached.

Fixed for 4.1.2 now, to be backported to 4.0.8 and 3.2.12.

Note that is a Tiles 2.x specific issue; it works fine with Spring's Tiles 3 support as-is. Out of curiosity, any specific reason why you're still on Tiles 2.x? We keep supporting it for the time being next to Tiles 3, just wondering...

We started our first roo project and surprisingly roo installed old versions of everything. We have updated the patch levels and will have to plan major upgrades too.

No worries, I'm sure there are plenty of existing Spring applications still using Tiles 2 simply because that's what they started with...

Our plan is to formally deprecate Tiles 2 support as of Spring Framework 4.2 in Q2 2015, and eventually remove it in early 2016.

Thanks. We will have upgraded by then.
