Alexey Kazakov updated JBIDE-12614:
-----------------------------------

    Steps to Reproduce: 
create class MyClass
{code}
public class MyClass {
	public MyClass() {
	}

	public MyClass(String n) {
		setName(n);
	}

	String name;

	public String getName() {
		return name;
	}

	public void setName(String n) {
		this.name = n;
	}
}
{code}
and bean class
{code}
import java.util.ArrayList;
import java.util.List;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.model.DataModel;
import javax.faces.model.ListDataModel;

@ManagedBean
@SessionScoped
public class MyBean {
	public DataModel<MyClass> getListDM() {
		return new ListDataModel<MyClass>(getList());
	}

	public List<MyClass> getList() {
		List<MyClass> res = new ArrayList<MyClass>();
		res.add(new MyClass("a"));
		res.add(new MyClass("b"));
		res.add(new MyClass("c"));
		return res;
	}
}
{code}
and use xhtml code 
{code}
<h:dataTable var="item" value="#{myBean.listDM}">
 <h:column>
    <h:outputText
	value="#{item.name}" />
 </h:column>
</h:dataTable>
{code}

  was:
create class MyClass
{code}
public MyClass {
  public MyClass (){}
  public MyClass (String n){setName(n);}
  String name;
  public String  getName() {
    return name;
  }
  public String  setName(String n) {
    this.name = n;
  }
}
{code}
and bean class
{code}
@ManagedBean
@SessionScoped
public class MyBean {
   public DataModel<MyClass> getListDM() {
      reuturn new ListDataModel<>(getList());
   }

   public List<MyClass> getList() {
      List<MyClass> res = new ArrayList<>();
       res.add(new MyClass("a"));
       res.add(new MyClass("b"));
       res.add(new MyClass("c"));
       return res;
   }
}
{code}
and use xhtml code 
{code}
<h:dataTable var="item" value="#{bean.listDM}">
 <h:column>
    <h:outputText
	value="#{item.name}" />
 </h:column>
</h:dataTable>
{code}

>             Project: Tools (JBoss Tools)
>          Issue Type: Bug
>          Components: jsp/jsf/xml source editing
>    Affects Versions: 3.1.1
>         Environment: Windows 7, Eclipse Juno
>            Reporter: Piotr Bezpalko
>            Assignee: Alexey Kazakov
>            Priority: Minor
>
> When using data model object (eg. javax.faces.model.ListDataModel<MyClass> -  bean.listDM) and h:dataTable (or rich:dataTable) Eclipse warns me on item presentation #{item.name) '"name" cannot be resolved'.
> {code}
> <h:dataTable var="item" value="#{bean.listDM}">
>  <h:column>
>     <h:outputText
> 	value="#{item.name}" />
>  </h:column>
> </h:dataTable>
> {code}
> If I change bean.listDM on bean.list (java.util.List<MyClass>), then no warning is displayed.
> After deployment both of version works fine.
