is not bound and can not be updated or BINDINGEXCEPTION ?

[Ken nashua]

Folks,

I am thrashing back and forth from

is not bound and can not be updated exception to a BindingException

Originally the app is runnable with
    public abstract String getTableSize();
    public abstract void setTableSize(String tableSize);

    public abstract String getPagingSpan();
    public abstract void setPagingSpan(String pagingSpan);

Then i decide to do this...
    @Parameter(required = false, cache = true)
    public abstract String getTableSize();
    public abstract void setTableSize(String tableSize);

    @Parameter(required = false, cache = true)
    public abstract String getPagingSpan();
    public abstract void setPagingSpan(String pagingSpan);

and I receive tableSize is not bound and can not be updated exception

So then i decide to goto the definition of the widget in the template... and 
specify the parameters there in OGNL

Home.html
    <div jwcid="[EMAIL PROTECTED]:Gallery"
            collectionType="ognl:@[EMAIL PROTECTED]"
            component="theWidget"
            collectionContent="collectionContent"
            autoPagingContent="autoPagingContent"
            tableSize="ognl:theWidget.tableSize"
            pagingSpan="ognl:theWidget.pagingSpan"
        >

Now I receive a bindingexception.

Can someone set me straight here? Do I need to edit my JWC file and add the 
following:
    <parameter name="collectionContent"/>
I should think not... but not sure?

Can someone elaborate on whats going on with this?

Best regards
Ken in nashua
