Problems reloading subsitemap
Hi,
I am running into a problem with reloading of subsitemaps. After initial startup everything runs fine but once I change a subsitemap treeprocessor can not find the correct components anymore. In fact it seems that the component locator in the CM is no longer valid. I am seeing the following warning in my logs.
WARN Thread-6 12:13:35:177 [sitemap] (): ComponentLocator exception from parent CM during lookup.
java.lang.IllegalStateException: You cannot lookup components on a disposed ComponentLocator

So CM is in illegal state when a lookup is done on it in DefaultTreeBuilder.getTypeForStatement(DefaultTreeBuilder.java:531).
As you can see I'm accessing cocoon thrue a custom servlet and Cocoon is initialized outside a particular webapp (inside my own container). Since I am not familiar with the treeprocessor internals I don't know where to start tracing this problem. Any pointers anybody?
This problem does not appear when the root sitemap changed.
Thanks,
Unico

Well, this should be my job to fix this, but I'm currently out of time :-(
Has somebody changed something recently in the TreeProcessor, or have
time to dig further ?
