Product: Tomcat 7
Version: trunk
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
AssignedTo: [email protected]

When i web.xml like this:
<filter>
<filter-name>Seam Filter</filter-name>
<filter-class>org.jboss.seam.servlet.SeamFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>Seam Filter</filter-name>
<url-pattern>/app/yofc/*</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>Seam Filter</filter-name>
<url-pattern>*.seam</url-pattern>
</filter-mapping>
then ApplicationFilterChain have two same Seam Filter.
this would cause some app error. Patch:
void addFilter(ApplicationFilterConfig filterConfig) {
for(ApplicationFilterConfig filter:filters)
if(filter==filterConfig)
return;
if (n == filters.length) {
ApplicationFilterConfig[] newFilters =
new ApplicationFilterConfig[n + INCREMENT];
System.arraycopy(filters, 0, newFilters, 0, n);
filters = newFilters;
}
filters[n++] = filterConfig;
}
