Is hashtable's append function broken?

Well, the title says everything. I tried to load and append data to a hashtable, but it didnt loaded anything at all. Am I doing something wrong, or this is an issue with the hashtable?

Edit:

The file is exists, and I can load it if I don't try to append.

You are right, it is broken. If you need to append data to a hashtable, you need to use one hashtable as a buffer and then copy the content of the buffer using "for each key"

pseudo event:

+ buffer: for each key

->hashtable: insert key buffer.currentkey with value buffer.currentvalue

Yup, I did the same while I was waiting for a respond. Thanks anyway.
