JXTemplate forEach assigns entire list to current
Hi all,
I have a forEach tag in my template, which behaves oddly. The variable
comes from an InputModule, which returns a List<String>, then it is
referenced as a parameter in the sitemap, which is passed to the
jxtemplate transformer. I would like to print each string as a line on
the output.
However, when I print #{.}, it prints the entire list, and the loop
quits after one iteration, regardless of the size of the list. When I
try Jexl syntax, it doesn't print anything. I am clueless.
Output is like this:
[value1, value2, ... ]
Here's the sitemap:
<map:match pattern="report.html">
<map:generate type="jx" src=".../templates/report.xhtml">
<map:parameter name="initSources" value="{skarabExt:initSources}"/>
</map:generate>
<map:serialize type="html"/>
</map:match>
Here is the template:
<jx:forEach select="#{$cocoon/parameters/initSources}" varStatus="status">
<jx:out value="#{$status/current}"/>
</jx:forEach>
I am using cocoon 2.2.0 and cocoon-template-impl 1.1.0 from Maven.
Thanks in advance!

This is perfectly correct, straight from the documentation, but in
JXPath syntax, which is slightly different than Jexl. I guess it has
only worked because of the different semantics of the expression.
varStatus contains the status variable, which can be used to access
various iteration parameters regardless of which syntax you use.

See forEach.

For all I know you're using the forEach incorrect.
<jx:forEach select="#{$cocoon/parameters/initSources}" varStatus="status">
<jx:out value="#{$status/current}"/>
</jx:forEach>
should be
<jx:forEach items="${cocoon/parameters/initSources}" var="element">
<jx:out value="${element}"/>
</jx:forEach>
Unless you really intended to show the varStatus?!
Kind regards,
Robby Pelssers

I have built a string from the elements, and used a Jexl expression to
re-split the string into a list. Ugly, but works.
