Double action call when scriptlets in iterate tag

[Maciej Kolodziej]

Hello,
Why, oh why this works:

<%
String btnKeyA = "images.AlarmComponent.btnActive";
String btnKeyIna = "images.AlarmComponent.btnInactive";
%>
<logic:iterate id="element" name="someBean" property="components" >
    <p>
        <logic:equal name="element" property="active" value="true">
<html:img srcKey="<%=btnKeyA%>" border="0"/>
            <div class="orange"><bean:write name="element" property="name"/></div>
        </logic:equal>
        <logic:equal name="element" property="active" value="false">
            <html:link page="/main.do" name="element" property="attributes">
<html:img srcKey="<%=btnKeyIna%>" border="0"/><br>
                <bean:write name="element" property="name"/>
            </html:link>
        </logic:equal>
    </p>
</logic:iterate>

while this doesn't:

  
<logic:iterate id="element" name="someBean" property="components" >
<%
String btnKeyA = "images."+((ComponentInterfaceAdapter)element).getName()+".btnActive";
String btnKeyIna = "images."+((ComponentInterfaceAdapter)element).getName()+".btnInactive";
%>
    <p>
        <logic:equal name="element" property="active" value="true">
<html:img srcKey="<%=btnKeyA%>" border="0"/>
            <div class="orange"><bean:write name="element" property="name"/></div>
        </logic:equal>
        <logic:equal name="element" property="active" value="false">
            <html:link page="/main.do" name="element" property="attributes">
<html:img srcKey="<%=btnKeyIna%>" border="0"/><br>
                <bean:write name="element" property="name"/>
            </html:link>
        </logic:equal>
    </p>
</logic:iterate>

And of course in the first case I cannot generate the strings I need with "name" property of "element".
Is it forbidden to place Java scriptlets inside the iterate tag? Because in the second case I get double call of main.do action and the second call doesn't have the attributes set.

in your second example, "element" is not a scripting variable--it is a variable in the pageContext. Try doing a pageContext.getAttribute() in order to access "element" in your scriptlet...

<%
ComponentInterfaceAdapter element = (ComponentInterfaceAdapter)pageContext.getAttribute("element");
String btnKeyA = "images."+element.getName()+".btnActive";
String btnKeyIna = "images."+element.getName()+".btnInactive";
%>
