On one, but not another, of two Windows XP machines the problem below
about argument types arises. I am so new to Simile that I don't even
know how to move the successful case to the other machine to get some
clues about what might be different in the two environments, nor could
I think of any (but unsuccessful, naive ) archive search strings to
find any other occurrences. The problem:
With Solvent, I make a small piece of javascript (below) and try to
run it with the Solvent code window Run button. Something---I suppose
it must be PiggyBank---raises an alert whose text is:
Error: There is no method
edu.mit.simile.piggyBank.WorkingModel.addStatement that matches
JavaScript argument types (undefined, undefined, undefined,
undefined). Candidate methods with the same name are: void
addStatement(java.lang.String,java.lang.String,java.lang.String,boolean)
It's perfectly clear to me what this message means. It's opaque what I
should do to look for a cause. Both Firefox installations are current,
both systems have JRE1.5
Thanks for any guidance.
