SuggestionBox depending on more than one field

[hipa]

I want to do autocompletion for 2 fields(variants for each field depend on other field value). But suggestionAction function have only one parameter. How can I send to server 2 fields values?

you may use f:param. Or you may set ajaxSingle to false and the whole region will be decoded on server (you'll be able to use values of the other components in the region)
