Slide tries to get contents of folder
I facing strange problem - I'm trying to create simple store (similar to
WebdavFileStore). I implemented just BasicWebdavStore interface. Everything
works fine while there is no directories created inside store, on clean
startup. But when I restarting tomcat, application crashes with this
exception:

As you can see in 1 and 3-d line, my store returns true for folder /files, so
I don't have any idea why slide tries to get contents of this directory.. Any
ideas?
I'm using latest Slide from SVN,

I had the same problem. Afaik the WCK performs some tests with the store
implementation on startup (e.g. writing to a directory). Have a look at the
reference implementation, that throws exceptions (like
ObjectNotFoundException when you try setResourceContent() on a directory).
If those exceptions are not thrown the WCK doesn't run correctly.

Okay, I didn't know about root directory for files, that really could be the
clue.

Two things,
/files is the root directory for content in default slide, it is normally
configured by Domain.xml on startup if it doesn't exist. If your store has
a different root for content that is probably the source of the problem.
However, if you follow my guide, you will find the problem, I can't/won't do
it for you.

Okay, but what about this: if I delete the 'files' directory, and then start
Tomcat, EVERYTHING works fine - no exceptions or whatever else. But if I
restart tomcat, it throws the exception and nothing works anymore. Makes
sense?

Well obviously it is hard to say without seeing the code (no I don't have
time to look at your code), but something you did say might be a clue.
You said, " my store returns true for folder /files, so I don't have any
idea why slide tries to get contents of this directory "
So do you understand that the "/files" node is a collection/folder? And
that it would be natural to get the contents of a root directory like
/files?
Things to check. What did you do differently in your store than are done in
the default Tx* stores? Replace one store at a time with your own stores,
this sometimes helps to identify what you did wrong as one store depends on
another in a chain sometimes it is hard to determine the actual cause as the
previous store call might succeed but be wrong in its implementation causing
the next store call in the chain to fail. Ensure your scope is the same
initially as the default Tx stores. Get a default working first with all
the Tx* stores so you have a reference with a working repository.
After that if you haven't figured it out, post your Domain.xml and error log
extracts (not the whole thing please) along with the offending Store source
method and maybe somebody will be able to help.
