RE: Iterate Problem

[Chris Cool]

Hi, Mark:

I am displaying "task" information in an HTML table using the iterate tag.
In the table are a set of input fields that allow my user to modfiy the
values of each task (in your case you may simply want to display the value
as readonly text). By using the "indexed = true" attribute of the "text"
tag, when you submit the html form struts will update each of the action
forms accessible via the getTasks()/setTasks() methods in
"MyTaskActionForm":



 
  

  
  

  
  

  
 


Hope this helps,

Chris

I sure seem to be having my share of problems with  this
week
 
My form bean (EditCustomerForm) has a property that sets and gets a List of
Customer objects.  These objects themselves contain the usual name, address,
etc. stuff.  I need to iterate through the collection of objects and display
the individual properties (like name, address, etc.) of each object.  The
Struts  TagLib documentation and Developer Guide are not particularly
useful in this regard.  We are adhering strictly to the Struts model and do
not want to use scriplets.
 
If anyone has figured this out, please post a solution.
 
Thanks,
Mark

Hi,
is there anyway to access the ActionServlet from inside a formBean or Action
class?

Thnx,

RE: returning the selected value from an

[Chris Cool]

Hi, Josef:

The way I handle it is to have three properties in my action form:

1. priority is the value that will be set in action form when the html for
is submitted.
2. priorityIds is the list of possible values that will be submitted for the
"priority".
3. priorityLabels is the list of Strings that appear in the select.

  

  

Hope this helps.

Chris

That I understand.  What I don't understand is how to
do that.  How can I reference the value chosen in the
select?  The id is tied to the bean.

RE: Tiles question: Is it possible to insert a ComponentDefinition into a Tile context dynamically?

[Chris Cool]

Hello, Cedric:

Thank you for responding to my question. 

As you stated, I can add/overload an attribute in the current context.
Specifically, I am adding a new item to an existing list. However, each item
in the list is the key to a Tile definition. Most of the definitions are in
the XML file, but I want to add a new Tile definition dynamically so that
the new item in the list is a reference to the new Tile definition. Is this
possible?

Thanks again,

Chris

  Hello,

  If you are in a tile controller, you don't have to create a new
ComponentDefinition, you can set the attributes of the current tiles
(because you
are in the controller).
  To add / overload an attribute in the context, do something like :
  String attribute = (String)context.getAttribute("attributeName");
  attribute = "new value";
  context.setAttribute("attributeName", attribute);

  To add a list, create the list, add elements, and add the list to context.
  You can overload a previously defined list. Do not modify content of an
existing list, because it is shared between inherited instances. :

   List list = new java.util.ArrayList();
  list.add( "a value" );
  list.add( "another value");
  context.setAttribute("listAttributeName", list);

  Hope this help,

Cedric

P.S. :
The DefinitionsUtil.setActionDefinition( aDefinition ); is to be used when
you
are inside a Struts action called by Struts mechanism.
  It has not effect when used inside a tile controller

Tiles question: Is it possible to insert a ComponentDefinition into a Tile context dynamically?

[Chris Cool]

Hi,

I have a tile that reads items from a PutList list and then inserts each
item into the current page. 

   
   
   

When the items in the list are tiles defined in my tileDefinitions.xml file,
the tiles are inserted into my JSP correctly. However, I want to dynamically
create a tile definition and insert it into the page context. 

I am generating the ComponentDefinition in my tile controller and accessing
the "itemList" where I add the name of the dynamically generated definition:

  /* get the item list and insert new tile def into it */
  ArrayList itemList = (ArrayList)context.getAttribute("itemList");
  if (itemList != null) {

HashMap map = new HashMap();
map.put("name", "newtarget");
map.put("link", "newtarget.do");

ComponentDefinition newItem = 
new ComponentDefinition("new.item",
  "/mytiles/simpleItem.jsp",
map);

DefinitionsUtil.setActionDefinition( request, breadCrumbItem );
itemList.add("new.item");
  }

In my tile, the "itemList" contains the "new.item" entry, but it does not
appear to find the ComponentDefinition I created.

Thanks for you help.

Chris

[Chris Cool]

Hi,

I have a tile that reads items from a PutList list and then inserts each
item into the current page. 

   
   
   

When the items in the list are tiles defined in my tileDefinitions.xml file,
the tiles are inserted into my JSP correctly. However, I want to dynamically
create a tile definition and insert it into the page context. 

I am generating the ComponentDefinition in my tile controller and accessing
the "itemList" where I add the name of the dynamically generated definition:

  /* get the item list and insert new tile def into it */
  ArrayList itemList = (ArrayList)context.getAttribute("itemList");
  if (itemList != null) {

HashMap map = new HashMap();
map.put("name", "newtarget");
map.put("link", "newtarget.do");

ComponentDefinition newItem = 
new ComponentDefinition("new.item",
  "/mytiles/simpleItem.jsp",
map);

DefinitionsUtil.setActionDefinition( request, breadCrumbItem );
itemList.add("new.item");
  }

In my tile, the "itemList" contains the "new.item" entry, but it does not
appear to find the ComponentDefinition I created.

Thanks for you help.
