"Faces Configuration" shown many times in Project Explorer

Question

in a Dynamic Web project i use Maven (m2e, m2e-wtp) and the JPA and JSF facet.
and it happens that the node "Faces Configuration" is shown up to 5 times in
the project explorer. after a clean one or some of these nodes vanish, but
after the clean and build is completed they are back again in the tree. I
already exported the project, reimported the project to a new workspace, but
the behavior is the same all the time. At the moment i am happy with only two
nodes visible in the explorer :)
And when i double click in one of those nodes i get the message in a popup
window saying:
No JSF configuration file exists in this project.
Please create a valid configuration file before performing this operation.
But there is a faces-config.xml in the src/main/webapps/WEB-INF folder and the
"Faces Configuration" nodes are able to show its contents, the navigation
rules, the managed beans and the converters.

Answer 1

I have not yet been able to reproduce the multiple instances of the "Faces Configuration" node, but other functionality has been addressed by the module core bug, https://bugs.eclipse.org/bugs/show_bug.cgi?id=121460. Until this bug was addressed, a lot of WTP functionality struggled with multiple folders being mapped to the web root.
When I make the following change to the "/.settings/org.eclipse.wst.common.component" file in an updated version of WTP, I no longer get the "No JSF configuration file exists..." message - that functionality is corrected:
OLD:
<wb-resource deploy-path="/" source-path="/src/main/webapps"/>
NEW:
<wb-resource deploy-path="/" source-path="/src/main/webapps" tag="defaultRootSource"/>
This can't be corrected in OEPE itself, it requires this WTP fix and will likely also require an m2e/m2e-wtp fix, since I imagine it is m2e-wtp that is creating the file.
I'm still trying to reproduce the multiple node issue; I have to wonder if it's related to the same fix as above, or if it is Linux-related. Do you ever see any other nodes duplicated in Project Explorer? I am continuing to attempt to reproduce. A zipped up project that demonstrates this behaviour might help considerably - let me know if that is possible.
Thanks,
