Array Reference

[ajpowellatl]

This loop does not seem to like the reference to the array via
application.production.getWorkLoad() where i is the index. Is there a way to
reference this array without dumping it into a local variable on the page?

Thanks for the help!

<cfloop from="1" to="#ArrayLen(application.production.getWorkLoad() )#"
index="i">
<tr>
<td><cfoutput>#application.production.getWorkLoad( )[i].id#</cfoutput></td>

<td><cfoutput>#application.production.getWorkLoad( )[i].client.name#</cfoutput>
</td>
<td><cfoutput>#application.production.getWorkLoad( )[i].agent#</cfoutput></td>
</tr>
</cfloop>

Not the way you're trying to do it, no.

However you could note that a CF array is in fact an implementation of a
Java vector, so you can do this:

i = application.production.getWorkLoad().iterator();
while (i.hasNext()){
writeOutput(i.next() & "<br />");
}

There's a CHANCE that Macromedia (or Adobe, by the time it becomes an
issue) might decide to stop making an Array be an implementation of a
Vector, in which case this code might stop working. Not sure the odds of
that happening are worth worrying about though.

This works great, with one exception. When it gets to the last column of the
last row, it bombs out. This is the error it throws:

java.util.NoSuchElementException

Any ideas? The data is there in the object (it's an array of objects)

Can you post your code?

Here you go:

<cfscript>
i = application.production.getWorkLoad().iterator();
while (i.hasNext())
{
writeOutput("<tr>");
writeOutput("<td>");
writeOutput(i.next().id);
writeOutput("</td>");
writeOutput("<td>");
writeOutput(i.next().client.name);
writeOutput("</td>");
writeOutput("<td>");
writeOutput(i.next().agent);
writeOutput("</td>");
writeOutput("</tr>");
}
</cfscript>

You don't want to make multiple calls to i.next(). Every call to i.next() takes
you to the next item in the iterator.

Try:

<cfscript>
i = application.production.getWorkLoad().iterator();
while (i.hasNext())
{
tmp = i.next();
writeOutput("<tr>");
writeOutput("<td>");
writeOutput(tmp.id);
writeOutput("</td>");
writeOutput("<td>");
writeOutput(tmp.client.name);
writeOutput("</td>");
writeOutput("<td>");
writeOutput(tmp.agent);
writeOutput("</td>");
writeOutput("</tr>");
}
</cfscript>
