Unresolved reference '//@class.1' [message #1726284]

We have a model and an Acceleo template to transform that model into web code.

The problem is that, in the model, the children of each element are ordered like this: 'hasOption="//@option.0 //@option.1 //@option.2 //@option.3"/>' and so on.

When trying to generate code from these models, we get an "Unresolved reference '//@option.1'" error, but it works fine if we reverse the order manually (like this: 'hasOption="//@option.3 //@option.2 //@option.1 //@option.0"/>').

Is there a way we can get Acceleo to read the elements in the correct/opposite order?

Here is an example of the model:

<?xml version="1.0" encoding="UTF-8"?>
<form_ecore:Website 
 xmi:version="2.0"
    xmlns:xmi="reference"
    xmlns:xsi="reference"
    xmlns:form_ecore="reference"
    xsi:schemaLocation="reference">
  <hasPage title="Google" hasForm="//@form.0"/>
  <form name="Login" send_text="Buscar" hasInput="//@text.0 //@combobox.0"/>
  <option value="1" display_text="1"/>
  <option value="2" display_text="2"/>
  <combobox name="tipo" label="Tipo" hasOption="//@option.0 //@option.1"/>
  <text name="Buscar"/>
</form_ecore:Website>

I don't see any reason why that should make a difference. You could try
using XMLResource.OPTION_DEFER_IDREF_RESOLUTION for loading.

Hi

You only provide 25% of a repro so your problem looks implausible.

Try opening and validating your file with the Sample Reflective Ecore
Editor which is always a good arbiter of whether model producer or model
consumer is at fault.

We found it was indeed a problem with the Ecore model, though the error didn't show up when validating it with the Sample Reflective Ecore Editor. Thanks for your replies!
