[Xsltforms-support] unpredicatble submission behaviour

[Immanuel N. <imm...@go...>]

Hi,

I still try to understand how submission put and get works. Exist-db comes
with the example
exist/webapp/xforms/hello2.xml (I assume it is known to you?! see
http://exist-db.org/exist/xforms/hello2.xml).

This example works basically as one expects. In order to learn from it I
made copy to

/db/my-hello.xml

and changed only two paths in that file to fit to my setting:

  <xf:submission id="put-to-db" method="put" replace="none"
resource="../rest/db/xforms-example-hello2.xml">

to

  <xf:submission id="put-to-db" method="put" replace="none"
resource="/exist/rest/db/xforms-example-my-hello.xml">

and


   <xf:submission id="get-from-db" method="get" replace="instance"
resource="../rest/db/xforms-example-hello2.xml?_query=/person&amp;_wrap=no">

to
    <xf:submission id="get-from-db" method="get" replace="instance"
resource="/exist/rest/db/xforms-example-my-hello.xml?_query=/person&amp;_wrap=no">

And this is my problem:

Let's say the initial content of /exist/rest/db/xforms-example-my-hello.xml
is

<person>
    <name>Otto</name>
</person>

When I go to http://localhost:8080/exist/rest/db/my-hello.xml everything is
displayed as in the hello2 example.

Now I type in the text: Anna
and push the button: Safe

This changes /exist/rest/db/xforms-example-my-hello.xml to:

<person>
  <name>Anna</name>
  <name>Otto</name>
  <name/>
  <name/>
  <test/>
  <name/>
</person>

Actually this is the same effect as in the hello2 example. The first
question here: why is

  <name/>
  <name/>
  <test/>
  <name/>

added? I would expect only a change to

<person>
  <name>Anna</name>
  <name>Otto</name>
</person>

But even more strange is the effect of the following interaction:

Let's start again with

<person>
    <name>Otto</name>
</person>

Now I type again the text: Anna
but push then the button: Refresh from DB

Still the content of  xforms-example-my-hello.xml is (as expected):

<person>
    <name>Otto</name>
</person>

However, when I type again: Anna
And then push the button: Safe

Then the content of xforms-example-my-hello.xml is:

<exist:result>
  <name>Anna</name>
</exist:result>

That's not I would expect. Instead I would expect again:

<person>
  <name>Anna</name>
  <name>Otto</name>
</person>

For me the behaviour of submission is thus rather unpredictable. Or do you
have an explanation? I would be very happy to learn how this submission
really works.
