I am in the process of upgrading from Struts 2.0.11.1 to 2.1.8.1 and am having some issues with the TabbedPanel.

Previously, I had customized how the TabbedPanel looks by setting the templateCssPath attribute to the location of a CSS file that was a copy of the provided TabContainer.css with my changes. I made a few minor changes which included pointing to different image files with different names. This worked great in 2.0.11.1. However, it does not appear to be working at all in 2.1.8.1.

When I look at the HTTP header in my browser, it does look like the control is attempting to do something with the templateCssPath that I provided. I just cannot tell what. In particular, I notice the following in my HTTP headers when using 2.1.8.1:

68:29:11.823   0.345  800   260   GET   200   text/css                                http://localhost:8180/sca/struts/TabbedPanel.css
68:29:11.961   0.274  823   1186   GET   404   text/html (NS_IMAGELIB_ERROR_NO_DECODER)     http://localhost:8180/sca/static/css/images/tab_left.gif
68:29:12.036   0.222  828   1201   GET   404   text/html (NS_IMAGELIB_ERROR_NO_DECODER)     http://localhost:8180/sca/static/css/images/tab_top_right.gif

If I remove the templateCssPath, I notice the following in my HTTP headers when using 2.1.8.1:

00:00:02.582   0.286  800   260   GET   200   text/css     http://localhost:8180/sca/struts/TabbedPanel.css
00:00:02.687   0.203  845   260   GET   200   image/gif     http://localhost:8180/sca/struts/dojo/src/widget/templates/images/tab_left.gif
00:00:02.770   0.126  850   260   GET   200   image/gif     http://localhost:8180/sca/struts/dojo/src/widget/templates/images/tab_top_right.gif

This is what is looks likes using 2.0.11.1 with the templateCssPath set:

00:00:47.149   0.233  1386   3919   GET   200   text/css     http://localhost:8180/sca/static/css/tabContainerGray.css
00:00:47.526   0.026  1405   518   GET   200   text/html     http://localhost:8180/sca/struts/dojo/src/widget/templates/TabContainer.html
00:00:47.645   0.131  1356   1556   GET   200   image/gif     http://localhost:8180/sca/static/images/gray_tab_left.gif
00:00:47.724   0.062  1361   3318   GET   200   image/gif     http://localhost:8180/sca/static/images/gray_tab_top_right.gif

Am I doing something wrong or is this a bug?

Thanks in advance,
Ken

Yes, I believe that is the case. If you use the Java Templates plugin it
switches the Templating Engine to Java. Since there are no themes defined
in the Java Template Engine other than simple, you're out of luck if you
want to mix themed and non-themed content.

I am finding the text regarding the enablement of Freemarker template caching in the performance tuning document (http://struts.apache.org/2.1.8.1/docs/performance-tuning.html) to be a bit confusing.

The document states:
<start clip>
As of Struts 2.0.10, setting the property struts.freemarker.templatesCache to true will enable the Struts internal caching of Freemarker templates. This property is set to false by default.

In Struts versions prior to 2.0.10, you had to copy the /template directory from the Struts 2 jar in your WEB_APP root to utilize Freemarker's built in chaching mechanism in order to achieve similar results.

The built in Freemarker caching mechanism fails to properly cache templates when they are retrieved from the classpath. Copying them to the WEB_APP root allows Freemarker to cache them correctly. Freemarker looks at the last modified time of the template to determine if it needs to reload the templates. Resources retrieved from the classpath have no last modified time, so Freemarker will reload them on every request.
<end clip>

I am confused. Do I or don't I need to copy the Freemarker templates to my WEBAPP to take advantage of the caching? Do I copy them to WEBAPP\template\.. or to WEBAPP\struts\template like with the static content?

Thanks,
Ken
