Concatenation of variables in JXTemplate

[Laurent Perez <ha...@gmail.com>]

Hello

I have the following declarations in my jx template :

<jx:set var="b" value="bean"/>
<jx:set var="l" value="${lang}"/>

Now I would like to access a bean property using ${bean.l} (call it a
'dynamic property'). For example when l = "foo", I would like to
access ${bean.foo}, but I don't understand how to evaluate the ${}
part :(

I've tried :

<jx:set var="b" value="bean"/>
<jx:set var="l" value="${lang}"/>
<jx:set var="dot" value="."/>
<jx:set var="both" value="${b.concat(dot).concat(l)}"/>

but whenever I access ${both}, I just get a string
"bean.value_of_lang", because evaluation failed.

Can anyone help me with the trick ?

Hi Laurent

Your problem is likely due to ${lang} not referencing a string type.

Have a look at this post and see if it helps
