Comparing two dynamic values
I'm trying to compare a parameter value passed in as part of the URL with a bean value. So I have something like this: . . In the "value" field - it says in the documentation that this has to be a constant value - which is pretty useless to me. I've tried: value="<%= request.getParameter( "id" ) %> but I get an error. Should this be possible? Anyone know if there is a more "Struts" way of doing it? Cheers Tony _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
Re: Error handling with taglibs
I would suggest requesting a change to the current struts implementation. I think this has been thought about because there is the facility to include the property that has caused the error. I would also like to do something like this. I suppose there would be at least two ways of going about it: 1) Make the ActionErrors component more accessible in the jsp page - so that some kind of logic tag could be used to generate either a normal html:text tag or an html:text error tag, or 2) Add an error attribute to the html:text tag (and others) that would render the text box differently if an error is associated with it. These are my thoughts.

RE: Posting Collections
Thanks Niall. I'm currently frustrated because I'm finding it hard to discover all the information I require. Seems to be a general lack of documentation on struts usage, but it's a learning curve like anything else. I like Struts in principle, and what it is trying to achieve, I just wondered if you considered it ready for building a large-scale project. For example, this change that you have submitted is going to affect a lot of code. So my options are to stick to my current solution without changing any of the Struts code, or modify the code so that it does what I want in the hope that the change will get propagated through to the next release. It doesn't feel like a good way to be working, but I take your point about Open Source, and I partly agree. For the time being I'm going to persevere - and I look forward to seeing your custom tags so I don't have to "hack around with the code every time a new version comes out".

Re: Checkbox Arrays
Yeah - I'm looking at that. My problem now is how to get the value for each
checkbox. My bean has an "id" property - so I have tried this kind of
thing:
"/>
But it doesn't like having the bean:write embedded there. Am I missing
something obvious?

Checkbox Arrays
Can anyone help with this?
I have an array of checkboxes in my ActionForm represented by
boolean[] delete;
and I have a setter function
public void setDelete( boolean[] values )
{
delete = values;
}
The problem is that I have only checkboxes that are checked get sent back -
so if one checkbox is checked all I get is an array of length 1. Therefore,
it is not possible for me to determine which checkbox has been checked.
In the documentation it tells me to use reset() in ActionForm to initialise
the values - but this will only work with single checkboxes and not arrays.
I think I'm stuck. Is there anyway I can determine which checkbox has been
checked - maybe I can get the value to differ for each checkbox. Will look
in to that.
Cheers
Tony
Design Error?
Cheers Dudley,
I have a solution but I am not happy with it (and I now also have the
additional problem that checkboxes only get sent back if they are set so I
can't tell which checkbox has been checked! - Another one to sort out).
Do you know if this is a design error. Basically, the problem is this (for
those who haven't been following the thread):
- I have a number of beans held in a Vector.
- In my ActionForm I have a two getters for this vector - one returns the
vector and one returns elements of the vector - so something like this:
public RetailerBean getRetailerBean( int index )
{
return (RetailerBean)retailers.elementAt( index );
}
and
public Vector getRetailers()
{
return retailers;
}
This works fine to populate using the following type of iterate tag:
-->
However, it doesn't repopulate the beans when I do a submit. This is
because the generated html is something like:
rather than:
which would allow my beans to be repopulated.
The outcome of this is that I have to create arrays for all properties of my
beans in my ActionForm and take the values from there. This seems like
bodge-heaven and not at all object-oriented.
If the form can be populated directly from the beans then surely it should
work the other way too.
Any struts developers want to comment?
Thanks for all your help.
Cheers
Tony

I think I am doing the same thing that you want to do using the
html:multibox. When the form is submitted you get an array of the ids that
are checked and then you can go delete them.
in the jsp form (where restaurant id is a key for the item being deleted):
...
...
in the form class:
private Long favoriteRestaurantRemoveList[] = new Long[0];
public Long[] getFavoriteRestaurantRemoveList() {
return (this.favoriteRestaurantRemoveList);
}
public void setFavoriteRestaurantRemoveList(Long
favoriteRestaurantRemoveList[]) {
this.favoriteRestaurantRemoveList = favoriteRestaurantRemoveList;
}
I am not sure if initializing the array to new Long[0] is necessary,
probably not.

i may have a solution for you, let me send u my one that works with a normal
edit box and see if u can change it to work with your checkboxes. i think
the basic idea, is that once your list is displayed, u need a String[]
setter like i have.
let me know...i've attached my files that actually work..
check it out and look at my comments

So you didn't need the extra method then? I think my problem is to do with
checkboxes and the way that they are implemented.

RE: Posting Collections
Many thanks Niall, that clears things up for me. Do you know if there is a
reason why this is the behaviour for checkboxes? Is this just with
checkboxes or other tags as well?
I don't really like the idea of modifying the struts code - the whole point
of deciding to use it is for code reuse - I don't want to start hacking
around with the code every time a new version comes out.
Do you have an opinion on using Struts? I've been using it for a couple of
weeks now and have been struggling because of basic lack of information. I
get most of my training from this news group! I'm wondering whether I
should just jack it in and use something else.
Cheers
Tony

RE: please help...iteration question...what i Have is...
I'm struggling with the same problem as you are (well similar) and general
lack of information / not being able to find information.
I think you may need the following method in your ActionForm bean:
public TaxPayerData getTaxPayers( int index )
{
return taxPayers[index];
}
as well as:
public TaxPayerData[] getTaxPayers()
{
TaxPayerData[] taxPayers = new TaxPayerData[list.size()];
taxPayers = (TaxPayerData[])list.toArray(taxPayers);
return taxPayers;
}
but if anyone else can comment on this - I would also appreciate
enlightenment.
Cheers

Briefly, this is what I am trying to achieve:
- Retrieve a list of items from a database
- Display each item with a corresponding checkbox
- Display a "Delete" button - which when pressed deletes all checked items.
Unfortunately, although I have managed to display the items correctly and
set the checkbox value using boolean values, when I do the form submit - my
ActionForm properties do not get filled in.
This is the code I have:
My ActionForm looks like this:
public class RetailerForm extends ActionForm
{
protected Vector retailer;
/*
* On construction, fill the form with all the retailers
*/
public RetailerForm() throws SQLException
{
//here i have some code to generate my vector
//which is comprised of "Retailer" beans.
}
public Retailer getRetailer( int index )
{
return (Retailer)retailer.elementAt( index );
}
public Vector getRetailer()
{
return retailer;
}
public void setRetailer( Vector value )
{
retailer = value;
}
}
My "Retailer" bean has get and set elements for properties called "delete"
and "name".
My struts code looks like this (obviously within tags):
And this all works ok for displaying the data. However, when I do the
submit my "delete" property for each bean is not set and I have added
debugging code to the "set" method and this is not called by struts. I
don't get error messages - it just doesn't happen.
I know other people have had this problem, but I am struggling to find a
solution.
Can anyone help me? Is there a better way of achieving what I am trying to
achieve? If I am doing the correct thing, what's the reason it's not
working.
All help appreciated.
Cheers
Tony
