Subject [jira] Commented: (COCOON-1737) JXTemplate Generater: set var problem
Date Thu, 19 Jan 2006 13:48:42 GMT

Werner Masik commented on COCOON-1737:
--------------------------------------

Sorry. I have to correct myself. The problem seems to be more complex than it looked like.
The bug cannot be reproduced with the example of my previous comment.
Further testing showed the following problems:

<jx:set var="gew_liste_id" value="Hello ${cocoon.request.get('liste_id')}" />
<liste_id path="${gew_liste_id}" />

leads to:
<liste_id path="Hello ${cocoon.request.get('liste_id')}">

instead of:
<liste_id path="Hello world">

(presuming that the request parameter liste_id contains the String 'world')
So the Jexl string ${cocoon.request.get('liste_id')} is not interpreted.

but without the Hello it works:
<jx:set var="gew_liste_id" value="${cocoon.request.get('liste_id')}" /> 

So maybe the documentation is wrong, or it's a bug. The workaround is to use the body:

<jx:set var="gew_liste_id">Hello ${cocoon.request.get('liste_id')}</jx:set>

The next problem is if you use a alias in another alias:

<jx:set var="gew_liste_id">Hello ${cocoon.request.get('liste_id')}</jx:set>
<jx:set var="testvar">the teststring is ${gew_liste_id}</jx:set>
<somexml myattr="${testvar}" />

leads to:
<somexml myattr="[Lorg.w3c.dom.Node;@1abcd5e" />

Once again it works if it is used in the body:

<somexml>${testvar}</somexml>

leads to:
<somexml>the teststring is Hello world</somexml>


That is what I actually tried to explain in my first comment. Sorry for the confusion.

is a alias and can be used like any other variable in the template. But it is not possible
to use it in a attribute value.

It works normal if it is used within the body.
