Question

I’m using EL 2.2 with Eclipse in xhtml pages.
How can I tell Eclipse to resolve keys with .concat(), like:

<h:outputText value="#{'message.xx.'.concat(cc.attrs.type)]}" />

Obvious the key does not exist in resrouce bundle in that way, bc it is dynamically build by the concat.
So Eclipse constantly claims of an invalid expression, further the xhtml pages are marked that they contain an error. Although it works in the webapp without a problem!

This is really annoying, how could I fix this?

Answer 1

not quite sure how you defined your bundle name , but lets call it bundleName

so use <ui:param to build your desired key , no .concat usage needed

incase you can access the cc.attrs.type by #{cc.attrs.type}

<ui:param name="messageSuffix" value="message.xx.#{cc.attrs.type}"></ui:param>
<h:outputText value="#{bundleName[messageSuffix]}" />
