Okay, I understand the problem now. Since the XML file represents a range of buffered items which are available once the file has been generated, you have to set the bufferSize-value to the count of items available in the xml file. In your given example, this would be "50".
I'll take care of this, just can't do it right now.
In your example the number is 5000 so I'm confused about any difference between your example and mine.
Perhaps I can give you the example:
/pflege/get-data-Netz.xml?start=10&limit=10 will produce
@sfrancolla - I'm just putting out my opinion. The following has nothing to do with Thorsten (MindPatterns). This version is still at 0.1 (alpha). So far there hasn't been an update. Just a sneak preview publishing - "official" publishing of the extension pack has been said to be made next weekend.
As for creating a project for it... ExtJS is a project. An extension or a component pack which is at least 5 very big/useful components could be a project. For an extension pack like this one will never need more than a changelog, live demo, usage information. Contributing with code/ideas is always welcome throughout the ExtJS community forum. You will just need to state your view and optionally post your code - you could as well zip your new code and attach it, or create a live demo somewhere. Creating a project (by that understanding changelog, bug tracker, suggestion posting, help, etc) for this is a bit far-fetched don't you think?
@Thorsten - it was bad that you gave your first name, in the first post to the thread. Now I'm inclined to use your first name, while others know/refer to you as MindPatterns
