Question

I’d like to pass an array as a GET parameter, say:

http://localhost/index.jsf?myArray=1stValue&myArray=2ndValue&myArray=3rdValue

Then I want to loop over that array:

<c:forEach var="p" items="#{param['myArray']}">
    <h:outputText value="#{p}" />       
</c:forEach>

I know this code won’t work.
But how can I do something like this?

Answer 1

You need #{paramValues} instead. It refers to HttpServletRequest#getParameterValues().

<c:forEach var="p" items="#{paramValues['myArray']}">
    <h:outputText value="#{p}" />       
</c:forEach>

or

<c:forEach var="p" items="#{paramValues.myArray}">
    <h:outputText value="#{p}" />       
</c:forEach>
