NullpointerException in org.orbeon.oxf.xforms.XFormsModel.performDefaultAction(XFormsModel.java:754)

All,

trying to set up a small user management application using OPS, but
having some problems with NullpointerException in
org.orbeon.oxf.xforms.XFormsModel.performDefaultAction(XFormsModel.java:754)

Here is my pageflow definition:
=======================
    <page   path-info="/users"
            id="users"
            xforms="oxf:/users/users.xforms.xml"
            view="oxf:/users/users.view.xsl"
            model="oxf:/users/users.model.xpl">
        <action when="/aspic:results/aspic:feedback/aspic:action = 'delete'"
                action="oxf:/users/delete.user.xpl">
            <result page="users"/>
        </action>
    </page>

(i.e. after deleting a user, re-run users.model.xpl and return to the same page)


Here is my XForms model:
=====================
<xforms:instance xmlns:xforms="http://www.w3.org/2002/xforms">
    <aspic:results xmlns:aspic="http://www.cruk.com/aspic/editor/v1">
        <aspic:feedback>
            <aspic:action/>
            <aspic:id/>
        </aspic:feedback>
        <aspic:users>
            <aspic:user>
                <aspic:email/>
                <aspic:firstname/>
                <aspic:lastname/>
                <aspic:username/>
                <aspic:id/>
            </aspic:user>
        </aspic:users>
        <request-security>
            <auth-type/>
            <secure/>
            <remote-user/>
            <role/>
        </request-security>
    </aspic:results>
</xforms:instance>

Here is my delete.user.xpl:
======================
<p:config xmlns:p="http://www.orbeon.com/oxf/pipeline"
          xmlns:oxf="http://www.orbeon.com/oxf/processors"
          xmlns:aspic="http://www.cruk.com/aspic/editor/v1">

    <p:param name="data" type="input" debug="input.data.for.delete"/>

    <p:processor name="oxf:null-serializer"
xmlns:p="http://www.orbeon.com/oxf/pipeline">
        <p:input name="data" href="data"/>
    </p:processor>

</p:config>

(i.e. do nothing for now - will add code to delete user record)


And here is my view:

Can anyone tell me if I am missing something obvious here? The
NullplointerException does not give me very much to go on..... It's
worth noting that taking out the 'action' element from the pageflow
definition causes the page to render just fine.

Thanks!

Henrik,

>Here is my pageflow definition:
>=======================
>    <page   path-info="/users"
>            id="users"
>            xforms="oxf:/users/users.xforms.xml"

Did you want to use the classic engine here? The @xforms means classic will
be used, if your learning this from new, then I would learn NG, remove this,
if this is a @default-submission (i.e. XML in your instance to start with)
then, it should be the XML for your instance, not the xforms:instance itself

>            view="oxf:/users/users.view.xsl"
>            model="oxf:/users/users.model.xpl">

Where is this file? What does it do?

>        <action when="/aspic:results/aspic:feedback/aspic:action =
'delete'"
>                action="oxf:/users/delete.user.xpl">
>            <result page="users"/>
>        </action>
>    </page>
>
>(i.e. after deleting a user, re-run users.model.xpl and return to the same
page) As I said above this XML should be stripped of the xforms:instance for the
your @default-submission

>Here is my delete.user.xpl:
>======================
><p:config xmlns:p="http://www.orbeon.com/oxf/pipeline"
>          xmlns:oxf="http://www.orbeon.com/oxf/processors"
>          xmlns:aspic="http://www.cruk.com/aspic/editor/v1">
>
>    <p:param name="data" type="input" debug="input.data.for.delete"/>

This should be @name="instance" to take data from the view
                       
You should use the xi:include, the XSL below won't work with
default-instance, unless your model does anything interesting?
noting that taking out the 'action' element from the pageflow definition
causes the page to >>render just fine.

Try those fixes and see what happens, the change to NG and input of the
delete.xpl might do the trick!

Ryan, all,

thank you, that worked! I was not aware that the new version of OPS
had changed the syntax for the pageflow definitions and I/O
definitions of the pipeline language. Tell me, do I need to set the
name attribute for output like this:

    <p:param name="instance" type="output"/>

or like this?

    <p:param name="data" type="output"/>

Sorry, I have not seen this in the documentation anywhere.

Also, I am not able to get the instance into the view using
xi:include. Perhaps this is related to the question above? Here is how
I am trying to import the instance data with xi:include (and failing -
nothing is returned):

         <xforms:model>
             <xforms:instance>
                 <xi:include href="input:instance"/>
             </xforms:instance>
         </xforms:model>

Is my syntax correct here? The documentation shows at least 2 ways of
specifying the href attribute :-)

If anyone knows the answer to these last 2 questions, I would be
eternally grateful:

1. This page presents a list of user entities, using xforms:repeat.
however, I am not able to highlight the different rows in the table,
like the "To Do Lists" example shows. Is my syntax correct?

2.My 'Delete' button does not seem to do anything. I would like it to
send back the userid of the currently highlighted row in my user
entities table, where the pageflow calls the
"oxf:/users/delete.user.xpl" pipeline. Is my syntax correct?

Thank you, everyone!  Code follows below.

That's all, I think.

Ryan, all,

thank you, that worked! I was not aware that the new version of OPS
had changed the syntax for the pageflow definitions and I/O
definitions of the pipeline language. Tell me, do I need to set the
name attribute for output like this:

    <p:param name="instance" type="output"/>

or like this?

    <p:param name="data" type="output"/>

Sorry, I have not seen this in the documentation anywhere.

Also, I am not able to get the instance into the view using
xi:include. Perhaps this is related to the question above? Here is how
I am trying to import the instance data with xi:include (and failing -
nothing is returned):

         <xforms:model>
             <xforms:instance>
                 <xi:include href="input:instance"/>
             </xforms:instance>
         </xforms:model>

Is my syntax correct here? The documentation shows at least 2 ways of
specifying the href attribute :-)

If anyone knows the answer to these last 2 questions, I would be
eternally grateful:

1. This page presents a list of user entities, using xforms:repeat.
however, I am not able to highlight the different rows in the table,
like the "To Do Lists" example shows. Is my syntax correct?

2.My 'Delete' button does not seem to do anything. I would like it to
send back the userid of the currently highlighted row in my user
entities table, where the pageflow calls the
"oxf:/users/delete.user.xpl" pipeline. Is my syntax correct?

Thank you, everyone!  Code follows below.

Henrik,

See my answers below
Both will work, data gives you input:data, instance gives you
input:instance. In a model you can use both, in a submission you must use
data.

You need an @id on your instance

How are you passing the data? Should be default-instance? Or use input:data
for the output of the model!
This is done automatically by the javascript, unless you have a class on the
elements to change the background, perhaps a reproducible example would be
good.

Ok your submission will have to look something like

<xforms:submission id="main" ref="instance('instance-id-to-send"
        method="post" action="users"
        replace="instance" instance="instance-id-to-replace"/>

Hope this helps
