simple flowscript array question

Hi,

I am simply trying to create a javascript array in flowscript.  The wiki 
and docs are peppered with such examples:

   var array = ["one","two","three"];

Or:

    var array = Array(3);
    array[0] = "blah";

For me, trying to create the array throws a:

org.mozilla.javascript.EvaluatorException: 	
file:/home/knoppix/workspace/DataServer_v2_1/build/webapp/admin/flow/model.js", 
line 154: Java constructor for "java.lang.reflect.Array" with arguments 
"number" not found


It looks like it's trying to create a java array, instead of a 
javascript array.  Can I force it to create a javascript array?


What on earth am I doing wrong?  Has something changed?

Thanks,
Greg

Hi Kranga,

This works :

try {
     ....
} catch (exception) {
     print(exception.message);
}

Is it possible to catch java exceptions in flow scripts? If yes, can someone
send me a snippet?

Thanks

Hi Greg,

What about
var array = new Array(3);

Re: Linking SQL Transformer and XSL Transformer

Hi Matt,

Using XSP and the ESQL taglib is way simpler for your example.
see http://cocoon.apache.org/2.1/userdocs/xsp/esql.html

Linking SQL Transformer and XSL Transformer

Posted by Matt Rich <ma...@pasteur.fr>.

Hello!

I'm currently trying to display sql request results in dropdown menus .

I think i must have three Transformers in my pipeline:

- I generate the requests from an XMl file through an XSL Transformer
- Then I try to execute the generated requests through an SQL 
Transformer
- Then I must rearrange the  results '  presentation with another XSL 
Transformer

Is that correct ?

(As for now, the problem must be I don't manage to generate the <sql: 
...> tags so that they can be read by the transformer :
I' ve tried this way :
          <xsl:element name="sql:execute-query">
         <xsl:attribute name="xmlns:sql" 
namespace="http://apache.org/cocoon/SQL/2.0"/>)

Has anybody an idea?

Many thanks in advance!!!

Matt

Hi Greg,

I'm not a javascript expert, but have you tried:

var array = new Array(3);

See:

http://devedge.netscape.com/library/manuals/2000/javascript/1.5/reference/array.html#1193137

Hope this helps,

John
