Greetings:
I am new to struts, and i have a question that has been giving me fits all
day.
I have a large application I am attempting to rewrite in struts, with
several hundred jsp's and servlets. It currently runs on Tomcat. I am
using, don't all of you laugh at once, 1.1-b3.
I haveured out some of how struts works from reading the samples and groping
throught the code, but i can't seem to figure out how to make logic:iterate
work. Here are a couple oc code fragments, if someone could point out where
i'm a bonehead, i would appreciate it.
In the Action class:
ArrayList components = ( ArrayList ) service.gatherAccessory
Bean.getContainer ( ) );
// Error checking and logging etc
if ( components != null && components.size ( ) > 0 ) {
System.out.println ( "Nav: Comp: " + components.size ( ) );
//txSupport component = new txSupport ( );
//session.setAttribute ( Constants.COMPONENT_KEY, components.get
( 1 ) );
//session.setAttribute ( Constants.COMPONENTS_KEY,
components.toArray ( as ) );
session.setAttribute ( component, components.get ( 0 ) );
navForm.setComponents ( components );
}
I have tried several alternatives as to how to set the id attribute:
- an empty instance of the Bean that is contained in the collection
- the first element in the array
I have tried to set the name property of the iterate to an array
all with different errors. The one that worked the best was when
I pointed the id property of iterate to the first element of the
Collection. Here i simply got the iterator to iterate the first
element. In the Action class I have iterated the Collection and
there are three elements in the list.
In the jsp:
<logic:iterate id="component" name="navigateForm" property="components" >
<tr>
<td COLSPAN="2"align="left">
<bean:write name="component" property="support" filter="true"/>
</td>
</tr>
</logic:iterate>
The navigateForm has a pair of methods get/setComponents that return the
Collection. If I put a logic:equal and test a member of the iteration it
works in all cases.
I am very perplexed by this situation and any light shed on the problem
would be appreciated.
Thanks in advance
