Portlet bindings are null for portlet component portlet1

Question

I have 2 simple portlets on a Web Center page.
I've added these at design time - the source JSPX shows
<adfp:portlet value="#{bindings.Portlet41_1}" id="portlet1"/>
It does not populate the required attribute portletType when I add this.
The page definition file shows
<portlet id="Portlet41_1"
portletInstance="/oracle/adf/portlet/MyPortlets/ap/Enportlet4default_c5eb69ff_012d_1000_8001_0a033796cd43"
class="oracle.adf.model.portlet.binding.PortletBinding"
retainPortletHeader="false"
xmlns="http://xmlns.oracle.com/portlet/bindings"/>
But at runtime, the page throws this exception
<WCS-39264> <Portlet bindings are null for portlet component portlet1.>
Am I missing an entry in any file?

Answer 1

Yannick - I have tried that exact sequence you've described. This is as per the tutorial.
It works intermittently when added via Design time - on some occasions - it gives the "Portlet bindings are null for portlet component portlet1" error. Other times, it shows the Hello World correctly.
When I see the error on screen, there is no stacktrace in the logs. I restart and it may (or may not) go away. Sorry - I dont have more pinpoint info than this.
My code is as in the first post - dragged and dropped ADFportlet from WSRP Producer, and the basic bindings were generated.
Now if added at runtime - it shows me the correct portlets via the Resource Catalog.
When I try to add, it just hangs for a very long time, without adding the portlet into the PanelCustomizable.
It adds other ADF components like Textbox properly
If I try Adding the portlet, or Adding a box below the panel or any operations more than once it gives this error
