I have this Java EE Web project where I am using Primefaces for UI components. I am using this import enum feature provided by Primefaces with an all-suffix. When my JSF PROJECT_STAGE is set to Development, everything works fine. When I change it to Production, I get below exception
javax.faces.FacesException: Class org.myorg.myEnum does not contain the enum ALL_OPTS

MY web page fraction is given below
<p:importEnum type="org.myEnum" var="opt" allSuffix="ALL_OPTS"/>
<p:outputPanel style="display:flex;">
<p:selectOneRadio id="one-radio"
value="#{myView.option}"
>
<f:selectItems value="#{opt.ALL_OPTS}" var="ui_opt"
itemLabel="#{ui_opt.displayName}"
itemValue="#{ui_opt}" itemLabelEscaped="false"/>
</p:selectOneRadio>
</p:outputPanel>
I thought it might be a bug, but when I tried in a standalone sample project with just one page with this web fraction and project stage set to production, It WORKS. I am puzzled now.

Import Enum has an option to define ‘allSuffix’. I had it defined to a custom string. When I removed it and used default ALL_VALUES, everything worked fine in Production PROJECT_STAGE.
I am not sure why, but it works. I need to dig more to understand.
Below is the fragment before which was throwing exception –
<p:importEnum type="org.myEnum" var="opt" allSuffix="ALL_OPTS"/>
<p:outputPanel style="display:flex;">
<p:selectOneRadio id="one-radio"
value="#{myView.option}"
>
<f:selectItems value="#{opt.ALL_OPTS}" var="ui_opt"
itemLabel="#{ui_opt.displayName}"
itemValue="#{ui_opt}" itemLabelEscaped="false"/>
</p:selectOneRadio>
</p:outputPanel>
Below is the working fragment —
<p:importEnum type="org.myEnum" var="opt"/>
<p:outputPanel style="display:flex;">
<p:selectOneRadio id="one-radio"
value="#{myView.option}"
>
<f:selectItems value="#{opt.ALL_VALUES}" var="ui_opt"
itemLabel="#{ui_opt.displayName}"
itemValue="#{ui_opt}" itemLabelEscaped="false"/>
</p:selectOneRadio>
</p:outputPanel>
**Note that allSuffix is not defined, and inbuilt name ALL_VALUES is used to refer to all enum values in f:selectItems. **
