[dtrussardi at tiscali.it]

Thank Johan,


> You will need to construct a valid javascript expression in the argument passed after #value:.

	i do some attempts but i don't find the right solution.
	In my smalltalk image i don't find a valid example how i can concatenate two value with a separator.

	Any reference ?

	I test this but the	 dict inspect   return an empty dictionary.

	I add the		 anHtmlRoot javascript 
						url: JSJsonDeploymentLibrary / #json2Js

	but with Safari  and Firefox don't work.

	Ciao,

		Dario
