[Qtitools-discuss] Minibix Bug

[Steve L. <sw...@ca...>]

Now that we have Minibix code on sourceforge I'm making sure I use this 
list for discussion of bugs in it!

I've been trying to upload a content package, regrettably a private one, 
and I'm getting the following error (see below).

Any clues?

[Raymond C. <ra...@ca...>]

The clue seems to be:

Caused by: uk.ac.cam.caret.minibix.metadata.api.BadFormatException:
Unexpected token CBRACKET at
uk.ac.cam.caret.minibix.metadata.impl.ParserImpl.parseExpr
(ParserImpl.java:92)

Can you see anything in your manifest file which could have caused that?

My metadata contains brackets galore, round ones and square ones. 
Surely these are allowed in fields like LOM:Description?

After some investigation with a bisection search through the items that 
were causing the problem I've discovered that:

<imsmd:keyword>
  <imsmd:langstring/>
</imsmd:keyword>

This was the culprit.  An empty keyword in the metadata triggers this bug.

Re: [Qtitools-discuss] Minibix Bug

[Dan S. <da...@ca...>]

If you add logging to the first line of parse_internal to print out the 
string "in" (or equivalent in a debugger) we can see what it's failing 
on. It's probably just a case of adding an else if to the parser method, 
but it's hard to see what it's barfing on at the moment.
