Usage of c:set for setting JavaBeans properties

[Roman Kapshevich <ro...@ucapital.ru>]

Hello!

I'm tryed to set property of my bean by <c:set> tag. But the exception was
thrown. Am I doing something wrong
or is it a bug in tag? I'm runing JRun 4.0 and Beta 2 JSTL.

<c:set target="${cart}" property="currentProduct" value="${i.key}"/>

Value is not null and it's looks like number. it's output succesfully.

Beans method is simple:

 public void setCurrentProduct(int currentProduct) {
    this.currentProduct = currentProduct;
  }

parameterize the locale through a beans' property

[kristian meier <km...@jentro.com>]

Hello,

I wanted to parameterize the locale for each request through a property 
of a bean, but the property is not propagated to the setLocale tag, so
the resources bundle is not found.

<i18n:setLocale value="<c:out value='${user.lang}'/>" scope="request"/>

<i18n:setBundle basename="com.jentro.Resources" var="locale" 
scope="request"/>

a workaround like the following does work, but it is sort of ugly

<c:choose>
  <c:when test="${users.user.lang == 'de'}">
    <i18n:setLocale value="de" scope="request"/>
  </c:when>
  <c:otherwise>
    <i18n:setLocale value="en" scope="request"/>
  </c:otherwise>
</c:choose>

do I have general misunderstanding of when and how to nest tags ?

best wishes
Kristian
