<bean:struts id="parameterMapping" mapping="/parameter"/>
This gets you an ActionConfig instance as a scripting variable and page-scoped attribute. Then, you can access both the scope and attribute name:
<bean:define id="formScope"
name="parameterMapping"
property="scope"/>
<bean:define id="formAttribute"
name="parameterMapping"
property="attribute"/>or with JSTL (which only creates scoped attributes, not scripting variables):
<c:set var="formScope" value="${parameterMapping.scope}"/>
<c:set var="formAttribute" value="${parameterMapping.attribute}"/>At this point, it's a lot easier to use JSTL to get a handle to the actual form:
<c:choose>
<c:when test="${'request' == formScope}">
<c:set var="form" value="${requestScope[formAttribute]}"/>
</c:when>
<c:otherwise>
<c:set var="form" value="${sessionScope[formAttribute]}"/>
</c:otherwise>
</c:choose>Now you've got a page-scoped attribute for the form. Using JSTL again, you can do something like:
<c:choose>
<c:when test="${form.structure_changeable == 1}">
...
</c:when>
<c:otherwise>
...
</c:otherwise>

Hi John, thanks for answering - you might be right on the issue I should use a EL tag instead of scriplet.
What i am basically interested in : When processing a jsp using a html:form tag, i guess html:form brings the current form bean object into some scope accessible to my jsp - but under what name does that tag expose it?
My form bean is defined in struts config as
<form-bean name="ParameterForm"
type="com.ucpmorgen.mobiletix.app.param.ParameterForm"> </form-bean>
Cause when used (please forgive my ignorance on your EL solution for now): <% if (ParameterForm.getStructure_changeable().intValue() == 1) { %> so.. uuupppps ... the jsp compiler always asked for a static method on ParameterForm. uuupppps , because I suddenly think that naming the variable like the class of form bean( the name after it is exposed later), is an most unlucky coincident, isn't it?!?!!? -> if is, then i should rename the bean name in the struts config.
Anyway, is the exposed from bean cast to the correct type for usage : - inside EL-Tag you wrote it is correctly typed - but for scriplet, isn't it just exposed as being of type java.lang.Object ?!?!

maybe I'm missing something, but if you use an EL tag (like the core:if or core:choose or logic-el:equals) you wouldn't need to do any scriptlet or casting.
<c:if test="${parameterForm.structure_changeable eq 1}">
</c:if>
as far as the constants, i'm not sure I follow. Hope this helps though...

Hi strut-users!
Since this post i have been using massively e.g. <bean:define id="parameterForm" name="ParameterForm" type="ParameterForm"/> in my jsp´s to grab the reference to the current FormBean like e.g.
<html:form action="/parameter"> ... <bean:define id="parameterForm" name="ParameterForm" type="ParameterForm"/> <% if (parameterForm.getStructure_changeable().intValue() == 1) { %> </html:form>
Please mail the applicable "shortcut" name (as i have forgotten the
full
name, has'nt it been sth. like "org.apache.struts....") and in which class those constants are denoted. Addendum : Once i got that
reference,
do i have to cast that reference to the correct form type - like : <%
if
(((ParameterForm)xxxFromBean).getStructure_changeable().intValue() ==
1)
{ %>
Tanks a lot Jörg
