Foreach-Troubles

[Reinhold Gruber <r....@deltavista.at>]

I have the following in a page template:

 

 

<loop jwcid="ownCredits@Foreach" source="ognl:person.ownCredits">

        <span jwcid="@CreditRenderer"
credit="ognl:components.ownCredits.value"/>

</loop>

 

person.ownCredits is an array with 3 items.
CreditRenderer.renderComponent(..) is called 3 times,

but always on the same CreditRenderer-Instance!!. I verified this by
putting a System.out.println() in the Default-Constructor of
CreditRenderer.

This issue causes problems because I lazy initialize some properties in
CreditRenderer and reseting them by implementing PageDetachListener.

I think you need to declare a "value" attribute in your loop component:

<loop jwcid="ownCredits@Foreach" source="ognl:person.ownCredits"
value="ognl:credit>
        <span jwcid="@CreditRenderer" credit="ognl:credit"/>
</loop>

And don't forget to declare a specification-property in your .page file.
