Re: databases and flow [again]

[Jason Lane]

Thanks Joerg!
I'd actually solved the problem that prompted me to post the original 
message but I shall need this info later on, I have a just the form 
that will need this.

Many thanks ;)

I guess not, but these samples would depend heavily on the persistence 
framework. And, yes, OJB block comes with database access samples. If 
you do th access in the flow script or in Java is up to you, I prefer 
the latter.

At the end the pseudo code looks like:
form = instantiateForm(definitionURI);
data = getData();
form.load(data);
form.showForm(sitemapURI);
form.save(data);
storeData(data);
showResult();
So you can separata the database access completely from the 
flowscript. No need for generating flowscript on the fly.

Couldn't I just generate the flow with the TextSerializer?
H�? I don't understand. Why generating flow with TextSerializer?
I think SQLTransformer or ESQL-Logicsheet will be your friend:
Yes that is good, but if I want to generate a flow.js from a DB? 
Surely I need to out put to a text format, which .js is.

So for example in my flow.js:
var $0 = [
   //these values from db
   { key: "$1", value: "$2" },
];
Where $0-2 are results of DB query.
Sorry I'm sure I'm totally missing the point here ;(
Don't generate the flow script, but access the values from a class 
that accesses the database.
