Null Container returned by getContainer
Hi,
I am trying to get the tiles definitions to work within folder. They seem to
be working on all root level files, but not inside folders. I am using the
BasicTilesContainer configuration with a tiles.xml file in the WEB-INF
folder. My error is as follows.
java.lang.NullPointerException
org.apache.tiles.template.InsertDefinitionModel.start(InsertDefinitionModel.java:74)
org.apache.tiles.jsp.taglib.InsertDefinitionTag.doTag(InsertDefinitionTag.java:276)
After attaching the source, I see that the line 217 in
org.apache.tiles.jsp.context.JspUtil.java calls getContainer(). Which in
turn calls an overloaded method of getContainer() on line 127 in the same
class. On line 127, I notice the following.
(TilesContainer) context.getAttribute(key,PageContext.*APPLICATION_SCOPE*);
I am suspecting that key is not being set or the attribute cannot be
retrieved given the appropriate key. They key should be set to
TilesAccess.CONTAINER_ATTRIBUTE. I guess someting in my Tomcat context is
not configured properly for this to not return the proper Tiles Container.
My web.xml looks like this
<servlet-name>tiles</servlet-name>
<servlet-class>org.apache.tiles.web.startup.TilesServlet</servlet-class>
<init-param>
<param-name>
org.apache.tiles.impl.BasicTilesContainer.DEFINITIONS_CONFIG
</param-name>
<param-value>
/WEB-INF/tiles.xml
</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
Do I need to specify some sort of a context param for the container to be
initialized and returned correctly? Please let me know.
Thanks,
Adi Saraf

I also suspect that the JspContext returned for the folders might be invalid
or null.
