|
| 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
