Hi Dan,
Since I was not able to replicate the hello2 example from
http://exist-db.org/exist/xforms/hello2.xml (see above) I am now trying to
get your example 1.8 running
http://www.danmccreary.com/xrx/beginners-guide/beginners-guide-to-xrx.xhtml#ex.edit.xq
Unfortunately, this doesn't work, too.
I copied and pasted example 1.8 under /db/apps/terms/edit/edit.xq
Did some corrections, namely replaced
xmlns:xs="http://www.w3.org/2001/<acronym>XML</acronym>Schema"
by
xmlns:xs="http://www.w3.org/2001/XMLSchema";
copied and pasted
*Example 1.10. /db/apps/terms/edit/next-id.xml*
*Example 1.11. /db/apps/terms/edit/save-new.xq*
Because $file in edit.xq refers to a file named "new-instance.xml", I
created a file /db/apps/terms/data/new-instance.xml with the following content:
**
*<term>*
* <id></id>*
* <term-name>my name</term-name>*
* <definition></definition>*
* <publish-status-code></publish-status-code>*
*</term>*
**
*Now I was able to load edit.xq?new=true and it was displayed as expected.*
*However, when I pushed the Save button, nothing happened. Hence,
something is wrong either with XSLTform.xsl or with the example.*
Again I tried to understand what is (supposed to) going on with the
submission element. First of all I don't understand why the instance
attribute has the value "my-task".
My guess is that it should point to an existing instance in the model.
Yet there is no instance named "my-task", but only one named
"save-data". Therefore I changed the value of the instance attribute
in the submission element accordingly.
Still pushing the safe button didn't yield any effect.
Then I read about Alain'2 comment that "AVT for XForms submission is
not supported". But that didn't help me any further.
It would be great to have a working example!
