Hi All!

After moved my project form ZK7 to ZK8 I get this error every time the page is loaded:

Failed to parse the expression [${.evmailSubjectBeans}]

It's caused by expression in "visible" attribute:

<chosenbox id="esuChosenbox"
           model="@load(ivm.evmailsubjects)" 
           selectedObjects="@bind(ivm.inventory.evmailSubjectBeansEntries)" 
           visible="@bind(!ivm.inventory.evmailSubjectBeansEntries.isEmpty())"/>

I found that problem in @DependsOn annotation on getter:

 @DependsOn("evmailSubjectBeans")
 public Collection getEvmailSubjectBeansEntries()
 ...

How can I fix this? It was working while the project used ZK7 and it's working without @DependsOn, but the annotation is needed for other functionality.

Thanks in advance!

I think you need to use not instead of !

Nope, the same error. It's not connected with expression syntax, other "visible" attributes with similar logic and syntax works fine. The problem in @DependsOn annotation and apparently how it's translated on page in new ZK8

is there a setter setEvmailSubjectBeans in the same class as whete the DependsOn is?

Sure, getEvmailSubjectBeans and setEvmailSubjectBeans both are in place

maybe bug, if you could create a sample in fiddle where you have same behavior, you could post it on bugtraker

Try:

visible="@bind(!ivm.inventory.getEvmailSubjectBeansEntries().isEmpty())"/>
