It works with JXpath expressions :
With this, I get What I need :
#{account/payer/lines[5]/CL1data/CL1_NUMLIG}
BUT
I need the number 5 to be replaced with the value of
account.payer.lines.currentLineIndex
So I thought of putting this value inside a variable using jx:set :
This works
<jx:set var="lineIndex" value="${account.payer.lines.currentLineIndex}"/>
var :${lineIndex} <br/>
But this doesn't work :
<jx:set var="lineIndex" value="#{account/payer/lines/currentLineIndex}"/>
var :#{$lineIndex} <br/>
I then need to do something like that :
<jx:set var="line" value="#{account/payer/lines[$lineIndex + 1]}"/>
So that I can get #{$line/CL1data/CL1_NUMLIG} or #{$line/CL1data/CL1_PRODUI}
But I'm stuck again...
To answer your question, I'm using javascript Objects, and javascript Arrays. I
took the petsotre block as an inspiration to build my webapp. Everything is in
flowscript ... I use this code to instanciate account.payer :
account = new Object();
account.payer = new Payer();
function Payer(codcli,codpay) {
this.data = null;
this.lines = null;
}
And to fill the array of lines, I use the javascript push() function like this :
account.payer.fetchLines();
Payer.prototype.fetchLines = function () {
this.lines = [];
var line = null;
try {
var conn = Database.getConnection("gptodb");
var resultCL1 = conn.query("select * from CL1 where CL1_CODCLI
= ? and CL1_PAYEUR = ?", [this.data.CP1_CODCLI,this.data.CP1_PAYEUR]);
for (var i in resultCL1.rows) {
line = new Line();
line.CL1data = resultCL1.rows[i];
line.fetchLITdata();
this.lines.push(line);
}
conn.close();
} catch(e) {
}
}

When you say "array"... what exactly is the lines object? A true Java
Array? A JavaScript array you created in flowscript? Something else?
In my experience JXPath expressions are more flexible in the kinds of
objects they know how to traverse, compared to Jexl expressions. Try:
#{account/payer/lines[6]/CL1data/CL1_NUMLIG} and see if it has any
better luck. Keep in mind [n] indexes in XPath are 1-based.
