Question

I cant figure out why this is not working. Basicly the following code-snippet workes fine unless the c:if is true.

If the if-statement is true, then clientId should be set manually to 1. This does work, but for some reason then it will not fetch the clientProps.

ClientId=1 does work fine if it is fetched from the session-variable ‘user’. So clientProps should have something at spot 1.
Any clue?

<c:set var="clientId" value="${sessionScope['user'].client.clientId}"/>
<c:if test="${empty sessionScope['user'].client.clientId}">
    True
    <c:set var="clientId" value="1" />
</c:if>

<c:set var="clientProperties" value="${clientProps[clientId]}"/>
<c:set var="clientLogo" value="${clientProperties.clientLogo}"/>
<c:set var="clientURL" value="${clientProperties.clientWebURL}" />
clientId = ${clientId}
clientLogo = ${clientLogo}
clientURL = ${clientURL}

Result if user-object exists:

clientId = 1 clientLogo = /images/logos/Logo1.png clientURL = http://www.xxx.xxx

Result if user-object doesn exist:

True clientId = 1 clientLogo = clientURL =

<c:set var="clientId" value="1" />

This is setting it as a String while the map key is apparently Long.

You need to set it as a Long instead.

<c:set var="clientId" value="${1}" />

Numbers in EL are implicitly treated as Long, that’s why the above will work.
