#13 Problems with Dictionaries

[gala81]

While using a simple processor with a dictionary
shared between every document and created only one
time, this processor seems not to realize that the
dictionary already exists, even if there's a brutal
check like
if(!dictionary.containsKey("Name_of_the_entry"))
{//Creation of the entry
}

So the second time the processor is executed, enters
in the if block, giving this warrant:

ERROR - failed batch

Where, obviously,
org.isobel.processors.IsobelPreClassifierTrainer is
the name of my processor.
Just to be complete here is the warning given by
Isobel gui:
