How do I specify conditions from 2 different beans in a jsf rendered attribute?

Question

I want to do something along the lines of the following but when I use it like this I get a parse error telling me an entity needs to directly follow the '&' character:

<ice:selectManyCheckbox
rendered="#{!bean1.condition1 && bean2.condition2}"
value="#{bean1.selected}">
<f:selectItems value="#{bean2.items}" />
</ice:selectManyCheckbox>

How can I get rendered to check conditions from 2 different beans?

Answer 1

Use 'and' instead:

<ice:selectManyCheckbox rendered="#{!bean1.condition1 and bean2.condition2}" value="#{bean1.selected}">

Answer 2

karim79 is right, you can just use the and operator.

In addition to that, you can have a look to this page, which explains the Expression Language (EL) with several examples...
