Error when using xforms:action with xforms:setValue

Hi,

I keep running into errors when trying to run the following code:

<xforms:action ev:event="xforms-ready">

<xforms:setValue ref="instance('categories-instance')/categories"

value="xxforms:call-xpl('http://localhost:8080/forms/categories.xpl', instance('categories-instance'),'formatted-output')/*, 'output')"/>

</xforms:action>

The exact error I get each time is: Invalid action: {http://www.w3.org/2002/xforms}setValue. My purpose here is try to populate an instance using a pipeline, but I don’t think it’s even getting there. Can anyone tell me what I am doing wrong to cause this error? It would probably be better if the error message told me what I was doing wrong, because I’ve seen people use xforms:action with setValue in some of the archives with no errors.

More detail, from the logs:

RE: Error when using xforms:action with xforms:setValue

Message

Hi Stephanie

Your error I think is because xforms:setValue should be xforms:setvalue.

However, the "ref" attribute of xforms:setvalue is a single node binding (http://www.w3.org/TR/xforms/#action-setvalue) - from your code it looks like you are attempting to update all or part of an instance (ie more than one node) - I don't think that will work.

Instead consider defining a submission to update the instance, and within your xforms:action have an xforms:send to kick off the submission.

Also, instead of calling your XPL directly, an alternative approach is to define a URL in your page-flow.xml which executes the XPL, and call that URL to update your instance.

Regards

Steve

Hi Steve,

Ah, yes that would be it. Don’t I feel stupid? J

Regarding the XPL, I have to call it directly as I am using a separate deployment scheme and thus have no page-flow.xml. I will try using the submission method and see if that might work better for what I am trying to do. This would all be so much easier if we could access the model from the DOM… If any devs are reading this, could it be possible to make that a setting?

Thanks!

Submit trigger: readonly dependant on the validity of fields

Hallo

I try to implement a submit trigger which is read-only dependant on the
validity of fields.
I dont get it. How do I have to define the readonly attribute of the
binding?

trigger:
<xforms:trigger ref="$control/submit-trigger">...

binding:
<xforms:model id="control-model">
<xforms:instance id="control-instance">
<control xmlns="">
<submit-trigger/>
<valid>
<LastName>false</LastName>
<FirstName>false</FirstName>
</valid>
</control>
</xforms:instance>
<xforms:bind
nodeset="instance('control-instance')">
<xforms:bind nodeset="submit-trigger"
readonly="not(valid/LastName = 'true' and valid/FirstName = 'true')"/>

</xforms:bind>
</xforms:model>

You can try my small test code.
Thank you very much for your answer :-)

Karolin

The issue is that in:

<xforms:bind nodeset="submit-trigger" readonly="not(valid/LastName =
'true' and valid/FirstName = 'true')"/>

The readonly expression is evaluated relative to the node pointed to
by nodeset. So it will look for a submit-trigger/valid/LastName and
submit-trigger/valid/FirstName. Instead, you can write:

<xforms:bind nodeset="submit-trigger"
readonly="not(context()/valid/LastName = 'true' and
context()/valid/FirstName = 'true')"/>

(You could also use ".." instead of "context()", but I find context()
cleaner. It is more a matter of personal preference.)

Access the model from the DOM? What do you mean by that?

RE: Re: RE: RE: Error when using xforms:action with xforms:setValue

Hi Alex,

I read in the archives that, via Javascript, we could not do something like "document.getElementById('myModelId')" or "document.getElementById('myInstanceId')" due to hiding them for security reasons. My point is that it would be really handy to have a setting to be able to update our instances/model via javascript which we currently cannot do.

Thanks,
Stephanie

Have you read this proposal about XForms-JavaScript integration: http://wiki.orbeon.com/forms/projects/client-side-api-for-custom-javascript-widgets

As far as I know, it has not implemented yet but it looks really good,
though.

If you want to modify Instance Data via JavaScript you can do that by
binding the elements you want to modify to hidden input fields. Then
just use JavaScript for modifying the value in that hidden input field
and it will be updated to the Instance Data.

Here is an example how to do it (haven't run the code so it might
contain mistakes).

<head>
...
<script type="text/javascript">
var your-variable = "Hello World!"; // Set value to a variable
using JavaScript
ORBEON.xforms.Document.setValue( "your-element", your-
variable ); // Set value to an element (Instance Data) using JavaScript
</script>
...
<xforms:instance id="your-instance">
<your-instance xmlns="">
<your-element />
</your-instance>
</xforms:instance>
...
</head>
<body>
...
<xforms:input class="hidden" id="your-element" ref="instance( 'your-
instance' )/your-element" />
...
</body>
