aj4:keepAlive is not working properly for me

[fmateo]

Hi All! I'm testing richfaces and ajax4java for a new project.
I tried to use keepAlive control to maintain one backing bean property between ajax request and a I got this error:

"<a4j:keepAlive beanName="#{productoBean.idProducto}"> Must be literal"

From richfaces documentation this should be valid.

May anyone tell me wich's the problem here?

Thanks

Perhaps i am wrong, but can it be that you should only use defined beans? Your beanName does not compare to a bean, because you point to a field of a bean. If "Must be literal" is what i think, you only can use #{LITERAL} where LITERAL is one of your configured beans from faces-config.xml. So 2 possibilities:

1.) Just keep the whole productoBean for your ajax request:

<a4j:keepAlive beanName="#{productoBean}">

2.) Also define idProducto as another bean and use it instead of productoBean:

<a4j:keepAlive beanName="#{idProducto}">

Bed is waiting, good night :)

<a4j:keepAlive beanName="productoBean.idProducto">
