Insert a new node between two old nodes
I want to design a web site where a user can insert a new object inside a
list of objects at a given position in the list.
The user enters a list of items in a <form> (name of the object, it price,
...) and when it submits this form I want to update an XML file containing
the whole list of objects.
Is it possible to do it with XSP ?
Something like this but the problem here is that I don't know the position
of my new node until the user as validated the form to give it to me :
<xsp:page
language="java"
xmlns:xsp="http://www.apache.org/1999/XSP/Core"
>
<objects>
<object>
<name>Knife</name>
<price>10</price>
</object>
<object>
<xsp:logic>
InsertNewObject()
{
...
}
</xsp:logic>
</object>
<object>
<name>Fork</name>
<price>15</price>
</object>
</objects>
</xsp:page>
Is it possible to modify the content of another XML file with XSP than the
XSP file itself ?

Mixing taglibs
Posted by Mats Norén <ma...@spectral.se>.
So if I want to mix two taglibs populate a form from a database and then save the
changes back to db...do I have to use the sql-processor and then use the xsp-processor
after...or the other way around ?

Ideally you should be able to mix the two.
1. The version of FP that you are using is flawed in various ways, I am
working on the upgrade which is a complete rewrite.
2. Donald and I use completely different techniques for writing TagLibs.
3. We have never had the time to ensure they work together.
Early days I am afraid .....

Ahh, I made a mistake and didn't include the esql-taglib properly..after doing that
it didn't compile.
Okey, so basically I have to find a workaround instead of mixing the two ?

We are not necessarily writing TagLibs to co-exist at the moment.
We are still learning the issues ....
Does this XSP page compile properly?
Can you work out from the Source code of your compiled XSP what is going wrong?

yeah - your XML isn't well-formed.

Yep, that was the problem. Thanks!
Another question ?
If I mix two taglibs on the same page...like for instance fp with esql the
esql-tags doesn't execute..
Example:
<?xml version="1.0"?>

Hi Mats ... mmmm , if your working on a Unix box, check if the files write
permissions are ok, remember that the FP examples and also the whole cocoon
engine will run using same user as the Servlet container you're working with (I
mean, Jserv by example runs as "nobody" by default ...).
Hope it helps ...

Sorry, I have no idea what is going wrong for you.
Do other XSP pages in the cocoon/samples work OK?

FP Taglib
Posted by Mats Norén <ma...@spectral.se>.
I'm having problems with the fp-taglib example.
When trying to edit or add paragraphs...nothing happens...nothing at all.
I see the edit/add pages but when I try to save the changes they don't go
through...
Any ideas ?
