Hi Alejandro,

what exactly do you need? I got a tiny code that turns a Uniface List into JSON! This will be part of my next "Uniface Frontend Templating" series (Part 4).

In case of beeing impatient, the code is not that sophisticated. JSON is a pretty clean form for structured data.

"Uniface uses the JSON format for updating dynamic server pages using websave and webload"

I would assume U9.4 NOT to deliver JSON directy for other purposes than websave and webload! If you want to digg deeper into this, then let me know :)

Saludos,

Hi,

I've got some very hacky and quite complex code for turning lists into JSON and vis versa - I had to remove UTF8 at the same time.

I'd be too embarrased to share it though.

I'd like to see more direct support and a more elegant solution

Just because I'm that curios ... @ AyeJay

Why do you want to return JSON into Uniface? ... I return those data as params which are accessible via $webinfo("input") ... or build Strings, that are Uniface-Like (eg. csv FIELD=VAL|FIELD2=VAL|) and replace "|" by gold internally (allthough we could also do that in JavaScript before sending the data back in).

Doing so makes it easier to handle it :)

My code looks like : http://www.udev.info/uniface/uniface-web-tools-ulist2json/

kind regards,

/EDIT: getting old, I guess. I already did that contribution with complete examples on 2010-07-23! ... *doh*

Interesting question - one I never really asked myself.

Because I was accessing someone else's web service and I was told I was going to get JSON as a response  and picking the data out of JSON in a sort of ad-hoc way is the idiom in the application in question.

I was doing this in the context of a uniface service rather than web page.

I'd like to find a better way - Always willing to share my mistakes (within the bounds of commercial confidentiallity) and hopefully learn from them

Thanks for the lists 2 JSON code

... you're welcome :)

Unfortunately the webload/websave commands do not have the same level of component structure mapping support that are available for xmlload/xmlsave. They just dump out the entire structure and currently only seem meant to support Dynamic Server Pages. We use an XSLT transformation to generate JSON from an XML document.
