xforms:output in the nightly build

Hi,

I have downloaded the nightly build of ops.war and tried to develop an ops application. One difference I noted is that for all the <xforms:output> which is not bound to any instance, all the instance elements gets appended to the <xforms:label> of the <xforms:output> node. Ie, suppose I have an <xforms:output> node like:

<xforms:output>

<xforms:label>First Name</xforms:label>

</xforms:output>

And an instance

<xforms:instance>

<main>

<name>Jency</name>

</main>

</xforms:instance>

When this is rendered, the label will appear as following:

First Name Jency 20

But if the it is bound to a specific instance as <xforms:output ref=”/main/namelabel”/> then it works as expected.

Is this a modification made in the new version? Is this the correct behavior?

Thanks in advance

Jency

Hi Jency,

That's a funny one, but I don't think this is new behavior in Orbeon Forms.

In fact, xforms:output must have either a @ref or a @value attribute. It
is not allowed to miss both these attributes.

What happens in your case is that it behaves as if you wrote ref=".",
and it returns the string value of the element.

Note that in XForms 1.1, we have made it clearer that a control cannot
even be bound to complex content this way.

I entered and fixed this bug so that you are no longer allowed to miss
both @ref and @value:

RE: xforms:output in the nightly build

Hi Erik,
In the ops version 3.5.1, the ref/value attribute was not mandatory for
xforms:output and it works by rendering the xforms:label inside
xforms:output. I usually use this for rendering static labels. If
ref/value is mandatory, then how do we render static labels? Do we need
to add these static values to some instance nodes and bind the output to
them? Or is there any other way to do so?

Thanks in advance
Jency

Are you saying that you were using this just to render a label, and
didn't expect the <xforms:output> to display anything coming from an
instance? If this is the case, I guess you can write <xforms:output
value="''"/>.
