Why are my comboitems outside of their combobox?

I am using ZK 8 with MVVM and form binding.

I have a Combobox with comboitems, which look like this in the *.zul file:

<window viewModel="@id('vm') @init('ulis.model.entity.webapp.viewmodels.PropertyViewModel')" form="@id('fx') @load(vm.property) @save(vm.property, before='saveProperty')">
<!-- Some unrelated code... -->

    <combobox hflex="1" model="@load(vm.propertyGroups)" selectedItem="@bind(fx.group)" value="@load(fx.group.name)">
        <template name="model" var="eachGroup">
            <comboitem label="@load(eachGroup.name)" value="@bind(eachGroup)" />

<!-- Some unrelated code... -->

In my ViewModel, I have a property field, a propertyGroups field and a group field. The model seems to be loaded correclty, and the selectedItem of the Combobox seems to work.

But, sometimes, I have a strange bug: the comboitems are duplicated outside their combobox. And there can be duplicates. This bug is not always there, but very often. I couldn't find a pattern where this always occurs.

I have insufficient karma to post screenshots, but it looks like this with the combobox closed:

|                            | V |
  Element one
  Element two

and like this with the combobox open:

|                            | V |
 | Element one              |
 | Element two              |

When the combobox is open, the duplicated elements that are outside of the box don't disappear.

How come this happens??

Thank you.

I was able to create a working test case, so I filed a bug (see issue ZK-2880).

The bug was fixed in ZK 8.

Hello Darksu,

I have exactly zero line of additional Javascript or CSS.

Thank you.
