#{//foo/bar} doesn't work within forEach!

[Stephan Coboos <cr...@gmx.net>]

Hello,

I've tried to retrieve an object within a JXTemplate:

#{//foo/bar}

This works fine outside any "forEach". If I'am using it inner forEach, 
nothing will be printed out:

<jx:forEach var="something" items="${myList}">

   #{//foo/bar}

</jx:forEach>

Because // refers to the root, the value should be printed out within 
this context, right? Whats wrong?

Thank you.

Regards
Stephan

Yes of course. But it should work, shouldn't it? Because something like 
this works, correctly:

<jx:forEach var="myItem" items="${myList}">

Item: #{.}

</jx:forEach>

Note: The iteration will be done by using Jexl. The node to print out 
will be selected by XPath.
So i think it is possible to mix Jexl and XPath.

Could it be that you are using both Jexl and XPath tags?

No. That won't work. With the current implementation of JXTG XPath 
evaluation of absolute paths with a <forEach> only works if the 
expression passed to <forEach> is an XPath expression. Does this work:

<jx:forEach var="something" items="#{myList}">

  #{//foo/bar}

</jx:forEach>
