I solved the problem using a ManagedBean. Concatenating the strings in the bean itself and reading it via EL-function call. I took this solution because I needed a value from the dialog-data-class and a value from the cms. This could not be solved in the JSF-Dialog due to the nested EL impossibility.

ManagedBean:

public String getCmsValue(){
        return Ivy.cms().co(getConcatenatedValues());
    }

JSF:

<h:outputText value="#{dialogBean.getCmsValue()}"

Not sure if I understand you right. You want to concat as string from the data class and one from the cms? Then you can use two el expressions the result of both expressions are concated.

Example:

<p:outputlabel value="#{ivy.cms.co('/dialog/lbInputtest')} #{data.sma}"/>

In your way I've never tried. I always (outsource) nested EL. For a workaround you can try something like this: In the Javasource you can join cms Strings easily. public String getRoleName(){ return Ivy.cms().co("/ch/lepa/common/roles/" + role.getName() ); }

Hi this works if the two values are both stored in the CMS.

What if one value is stored in the data class and this value should get concatenated with something from the CMS?

How to do that? like data.sma is a value from the data class.

Nesting EL expressions is illegal syntax. You should see the #{} as one big space where variables/strings can interact with each other.

Use #{ivy.cms.co(data.sma.concat('/dialog/lblInputtext'))}
