Nested JSF EL

Question

Hi there! Another fun JSF related question.

I want a nested el:

<ui:param name="sma" value="#{data.sma}/dialog/lblInputtext')}" />
<ui:param name="smalbl" value="#{sma}" />
<h:outputText value="#{smalbl}" style="height: 300px; width:450px"/>

The output is the following:

#{ivy.cms.co('/sma25/dialog/lblInputtext')}

I want exactly this output evaluated by jsf. It doesn't work when I put the result in #{} one more time. JSF prints out a warning due to wrong syntax.

Has anyone else tried to nest el's?

thx for help!

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()}"

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

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.

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() ); }

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}"/>
