Binds, nested repeats

I have a set of xml:

<Manifest>
<ManifestInformation>
<Shipment>
<TransportEquipment>
<ContainerNumber/>
<ServiceCode/>
<ContainerType/>
</TransportEquipment>
</Shipment>
</ManifestInformation>
</Manifest>

Where shipment and TransportEquipment are both repeating items. I want to set the ContainerType as readonly, but only when its value is NC. I tried:

<xforms:bind nodeset="instance('instance_model_SeaManifest')/ManifestInformation">
<xforms:bind nodeset="Shipment">
<xforms:bind nodeset="TransportEquipment">
<xforms:bind nodeset ="ContainerNumber" readonly="1" if="ContainerNumber = 'NC'"/>
</xforms:bind>
</xforms:bind>
</xforms:bind>

But this only sets it as readonly, ignoring the condition. Any hints as to what I did wrong?

Chris,

The readonly property takes an XPath expression that evaluates to a
boolean. So you would want to use true() as opposed to just 1, but
even better, just put readonly=". = 'NC'" and you should be good.

You want to set the ContainerType as read-only when its value is NC,
so instead of:

<xforms:bind nodeset ="ContainerNumber" readonly="1"
if="ContainerNumber = 'NC'"/>

You should have something like:

<xforms:bind nodeset ="ContainerType" readonly=". = 'NC'"/>

Nodeset has to point to the node on which you want to set the
"read-onlyness", and readonly is an XPath expression that determines
if the node will be read-only or not.
