Tapestry5.4.1 Exception : ParameterParameter 'selected' of component
is bound to null.
Not sure what I am doing wrong.
I am getting this exception from .tml file
Parameter 'selected' of component zone/Edit:stores is bound to null. This
parameter is not allowed to be null.
In my .tml file I have
<style>
DIV.t-palette SELECT { width: 300px; }
</style>
- - - - -
- - - - -
<t:palette t:id="stores" selected="stores" encoder="storeEncoder"
model="storesModel"
t:deselect="context:images/arrow_left_new.png" validate="required"
t:select="context:images/arrow_right_new.png" >
In my java class I have:
@Property
private List<Store> stores; // Store is a simple pojo
The class doesn't have any 'selected' variable but does have some
'onSelectedXXXX' method.
I have checked other posts related to the same issue but those are not
exactly the same problem.
I will appreciate any suggestion.
Thanks.

After changing our code to make sure 'stores' is not null it works now.
Thanks so much !!

Thank you Cezary! For the quick response and providing the insights.
Indeed we are upgrading our tapestry from version 5.1.0.5 to the 5.4.
I will check our code .

You are using Palette component from Tapestry. It has a parameter called
"selected" that must be provided with non-null value. In your case it is
bound to your "stores" field. You must ensure that "stores" is always
non-null. Note that, according to the documentation, before T5.4 "selected"
was allowed to be null, so if your application was working before with
Tapestry 5.3 (or older), you need to change your code appropriately.
Best regards,
Cezary
