Please see this picture of Chrome and IE 6

In Chrome the right listbox is displayed correctly and the in IE6 the listbox does not.

This was working fine in v5.05 in IE6.

The listbox has a ListitemRenderer.

Just noticed that if I resize the browser in IE6, the listbox then displays correctly, if I resize the splitter on the screen both listbox fails to display correctly.

Hi,

Can you provide a simple test case that replicate the issue?

Thanks,
Simon

Hi Simon,

Here is some code:

test.zul

    <borderlayout>
      <north title="Search Criteria:" collapsible="true">

              <textbox id="first" value="@{fixed.firstName}" />
            </row>
            <row>
              <label>Second:</label>

TestController.java

package test;

public class TestController extends GenericForwardComposer

    for (int i = 0; i < 100; i++)

      boolean married = false;
      java.util.Random rn = new java.util.Random();
      int r = rn.nextInt(10);
      if (r > 5)
        married = true;

      customers.add(new Person(randomstring(4, 6), randomstring(4, 6), married));
    }

    fixed = new Person();

  }

  public void onSelect$list( Event event )

    Person selected = (Person)list.getSelectedItem().getValue();

        {
          comps.add(b.getComponent());
          break;
        }
      }
    }
    for (Component c : comps)
    {
      binder.loadComponent(c);
    }
  }

  public static String randomstring( int lo, int hi )
  {
    int n = rand(lo, hi);
    byte b[] = new byte;
    for (int i = 0; i < n; i++)
      b<i > = (byte)rand('a', 'z');

  }

  private static int rand( int lo, int hi )

  }
}

Person.java

package test;

public class Person
{
  private String  firstName = "";
  private String  lastName  = "";
  private boolean married   = true;

  public Person( )
  {

  }

  public Person( String firstName, String lastName, boolean married )
  {
    this.firstName = firstName;
    this.lastName = lastName;
    this.married = married;
  }

  public boolean isMarried( )
  {
    return married;
  }

  public void setMarried( boolean married )
  {
    this.married = married;
  }

  public String getFirstName( )
  {
    return firstName;
  }

  public void setFirstName( String firstName )
  {
    this.firstName = firstName;
  }

  public void setLastName( String lastName )
  {
    this.lastName = lastName;
  }

  public String getLastName( )
  {
    return lastName;
  }

  // getter and setters

  public void setFullName( String f )
  {
  // do nothing
  }

  public String getFullName( )
  {
    return firstName + " " + lastName;
  }
}

This code doesnt produce the error exactly how it happens on our system, but its close enough - in IE6 when the screen is displayed resize the splitter and the left listbox will mess up.

It seems to be a bug in 5.0.6. I have posted it here.

Meanwhile, you can try to put a Div between the West region and the listbox:

	<borderlayout>
		<west size="40%" flex="true" splittable="true">
			<div hflex="1">
				<listbox vflex="1" hflex="1">
					<listhead>
						<listheader label="First" />
					</listhead>
					<listitem>
						<listcell label="1" />
					</listitem>
					<listitem>
						<listcell label="2" />
					</listitem>
					<listitem>
						<listcell label="3" />
					</listitem>
				</listbox>
			</div>
		</west>
		<center>
			<div>
				Div Content
			</div>
		</center>
	</borderlayout>
