[daisy] How To set a multivalue-field in documenttask

[Karel Vervaeke]

So you need to chant the right incantation and hold some chickenbones
in the moonlight. 

Sorry, friday afternoon and all that, here's what you need:

['template'] is not seen as a java array (because, technically speaking,
it really isn't, it's a Javascript array thingy).

To create a Java array, you should write something along the lines of :

var valueArray =
Packages.java.lang.reflect.Array.newInstance(Packages.java.lang.String,
1)
valueArray[0] = 'template';

HTH,
Karel

ps: you may even need to write Package.java.lang.String('template'), but
I'm not sure.
