BUG JSF Select Item not binding properly

Question

Dear Oracle,
I'm running JDeveloper 10g version 10.1.3.0.3.3412 early access 1. If you create a HTMLMenu1 select list in a JSF Page and use the properties dialog to bind the values to a backing bean, the binding get's lost and the page doesn't call the value binding. What's more, if you try to rebind the values using the dialog, JDeveloper repeatedly inserts a new SelectItems tag for the menu.
For example, if you create the SelectMenu1 and then use the dialog to bind the selectItems to a backing bean property, you will end up with code something like this:
<h:selectOneMenu binding="#{backing_showFactory.selectOneMenu1}"
id="selectOneMenu1"
valueChangeListener="#{backing_showFactory.selectFactoryEvent}"/>
<f:selectItems value="#{backing_showFactory.allFactories}"
binding="#{backing_showFactory.selectItems1}"
id="selectItems1"/>
Now, click on the newly created menu item in the design window of the JSP editor and bring up the properties dialog. You will see that the value binding is blank. If you reenter the value binding information, JDeveloper creates a new tag so you end up with the following:
<h:selectOneMenu binding="#{backing_showFactory.selectOneMenu1}"
id="selectOneMenu1"
valueChangeListener="#{backing_showFactory.selectFactoryEvent}"/>
<f:selectItems value="#{backing_showFactory.allFactories}"
binding="#{backing_showFactory.selectItems2}"
id="selectItems2"/>
<f:selectItems value="#{backing_showFactory.allFactories}"
binding="#{backing_showFactory.selectItems1}"
id="selectItems1"/>
Each time you repeat the process, JDeveloper creates another tag:
<h:selectOneMenu binding="#{backing_showFactory.selectOneMenu1}"
id="selectOneMenu1"
valueChangeListener="#{backing_showFactory.selectFactoryEvent}"/>
<f:selectItems value="#{backing_showFactory.allFactories}"
binding="#{backing_showFactory.selectItems3}"
id="selectItems3"/>
<f:selectItems value="#{backing_showFactory.allFactories}"
binding="#{backing_showFactory.selectItems2}"
id="selectItems2"/>
<f:selectItems value="#{backing_showFactory.allFactories}"
binding="#{backing_showFactory.selectItems1}"
id="selectItems1"/>
Either way, if you clean up the JSF page with the spurious tags, the value binding (in the example above backing_showFactory.allFactories), is never called.

Yes - this really is a bug. Any changes to make to the selectItems tag through the properties dialog rewrites the tag source code to seperate the selectOne tag and the selectItems tag. For example, before you use the dialog, you tag code could look like this:
<h:selectOneMenu binding="#{backing_showFactory.selectOneMenu1}"
id="selectOneMenu1">
<f:selectItems value="#{backing_showFactory.allFactories}"
binding="#{backing_showFactory.selectItems2}"
id="selectItems2"/>
</h:selectOneMenu>
After the use of the dialog the code will be rewritten as:
<h:selectOneMenu binding="#{backing_showFactory.selectOneMenu1}"
id="selectOneMenu1"/>
<f:selectItems value="#{backing_showFactory.allFactories}"
binding="#{backing_showFactory.selectItems2}"
id="selectItems2"/>
Notice, the tags are now seperated instead of the selectItems tag being encased in the selectOneMenu tag.
