i will check this asap

accepted for evaluation

it is true that the thrown exception contains no description but that is another
topic (inconsistent error handling ...)

But i would expect that you simply use the API wrong here. What do you want to
achieve? First take a look into the description of XStorable. You can't use
store() on a new document before you have stored it to an URL. getLocation() on
a new document retunrs an empty string and can cause a problem as well ->
depending how it is used. 

When i create a new document, use storeAsUrl or storeToUrl (see the decription
for the difference) and use later store() or again storeToUrl everything works
as expected and no exception is thrown.

I'm not trying to store new document. I'm trying to store document which I 
opened. 
I used 
xComponent = aLoader.loadComponentFromURL("file:///" + fajl, "_blank", 0, pv);
xTextDocument = (XTextDocument)xComponent; 

to open existing odf file.
I changed it.
I tried to save it with same filename.

it works for me with a loaded document as well. I don't know what you are doing.
Although storeToURL with the same URL as the loaded document makes not really
sense but it works. The document on the disk is changed and the document in the
office has still the status "changed". But when i close the document without
saving and load it again i got the latest changes from storeToURL. I got no
exception!!

Ok, here is simple POF

It breaks on line xSave.storeToURL or on xSave.store()

your example works fine for me. But of course  you don't prepare a valid URL in
LoadDoc. Your input is "c:\example.odt" and you don't convert the backslash.
However, the example works fine for me and i got no exception.
I tested the example with an office based on a m196 source tree and a .NET 2.0
framework. I don't expect that this makes the difference but you can at least
check it with a newer development build of the office.
