RE: Dynamic list of strings in a form
(Apologies - I sent the wrong tml file - please ignore my last email)
I've been trying to use FormInjector to create a dynamic form and not getting
very far. I've taken the demo that Igor gave links to and simply taken it out
of the border element. It works fine unless I add the t:label component in the
block. It seems to me that as soon as there is more than one kind of component
in the injected block, the inserted HTML is just "" without any form elements. Two textfields work, and
a textfield and an 'any' component work, but not label or radio with a
textfield. I suspect it's all form components.
Here's the modified demo. Remove the label component to see it working. Add
back in to see it broken again. I think this might be connected with
TAPESTRY-2322.
Am I doing something wrong here, or is it a bug?

RE: Dynamic list of strings in a form
I've not seen these demos before and although they look like integration tests,
they also look really informative and very useful starting points for
experimentation. There doesn't seem to be any release or package with them in
and I can't figure out how to retrieve them en masse from the svn repository
(probably don't have permissions anyway) so is there any way to get hold the
source of these demo/test apps to learn and play around with? Obviously I could
get a file at a time from the viewvc webpages.. but that would take a rather
long (and boring) time.

Re: Dynamic list of strings in a form
Thank you very much, that was exactly what I was looking for. I am new
to tapestry and it was not clear for me how loops are working, but now I
understand it. :-)
Also many thanks to the other guys that replied.
@Marcus: Grid didn’t work for me, because I didn't have any Bean that I
could pass.
@Francois: Looks like a nice component and a generic solution for that
kind of problem. But I think it was bit overkill for me.
@Igor: FormInjector may work, if I always start with one input field.
But I also have to provide an edit form where already can be a set of
values. I am not sure how I could implement this using the FormInjector.
Regards,
Michael

Re: Dynamic list of strings in a form
Hey Michael,
I know a couple of guys have replied, but I think there is a much
simpler answer to your problem.
drop the item property from your page and add getter/setters that
update the your items list based on the index in the loop:
@Property
private int _index;
public String getItem() {
if ( items.size() <= _index ) {
// what to do when the index is out of bounds?
}
return items.get(_index);
}
public void setItem(String s) {
if ( items.size() <= _index ) {
// what to do when the index is out of bounds?
}
items.set(_index, s);
}
and update the loop div in your template to bind the index property:
The way your page was written you were telling tapestry to update the
item property for each value in the list, which it dutifully did. But,
what you really wanted was it to put the items into your list.
Hope that helps,
Josh

Re: Dynamic list of strings in a form
Hi Michael, Try Grid component instead a Loop. Marcus
Re: Dynamic list of strings in a form
Michael Dukaczewski wrote: [...] I have a list of values, the user has to enter. The number of values, that have to be typed in, is dynamic, so the user has to extend the form. The add button works, but the values are not saved. Can someone tell me, that I am doing wrong? It can't work because after the loop is rendered, you don't have a conduit between list item and the textfield anymore. You should look at what is done in the beaneditorn and just use it and provide your own "listmodel", which would be a special bean model where properties are the elements of the list. Ok, I see that I'm really clear :) Here is an example of what I've done some time ago. It is an hight level component that takes a list of "something" and create and form for it (all element of the list are editable thanks to the "something editor", an add button allow to add a blank element at the end of the list, and a delete button follow each field). (Note : it was done in an old T5 version, and should take advantage of all the new nice features like Generics in components) The java part: http://sventon.ow2.vservers.linagora.com/svn/showfile.svn?path=/interldap-wui-common/trunk/src/main/java/org/interldap/wui/t5lib/components/ListEditor.java&revision=HEAD&name=interldap_ow2 And the matching template : http://sventon.ow2.vservers.linagora.com/svn/showfile.svn?path=/interldap-wui-common/trunk/src/main/resources/org/interldap/wui/t5lib/components/ListEditor.tml&revision=HEAD&name=interldap_ow2 So, the part that you want to look at is the "ListObjectBeanModelSource" : http://sventon.ow2.vservers.linagora.com/svn/showfile.svn?path=/interldap-wui-common/trunk/src/main/java/org/interldap/wui/t5lib/data/ListObjectBeanModelSource.java&revision=HEAD&name=interldap_ow2 Ok, an real life example that build a "composed search filter" (the like you have in thunderbird when you want to search email on multiple criteria) : http://sventon.ow2.vservers.linagora.com/svn/showfile.svn?path=/interldap-wui-common/trunk/src/main/resources/org/interldap/wui/t5lib/components/search/SearchCriterionComposition.tml&revision=HEAD&name=interldap_ow2 Each criteria is an element in the list, there is an editor for criterium added in the know editor of bean editor, and that's all ! This simple component build the form for you. There is a big drawback: this kind of feature should be made only client side, or almost. Here, each add/remove send a request to the server...

Re: Dynamic list of strings in a form
Have a look at the FormInjector component. This component is what you need.
http://tapestry.apache.org/tapestry5/tapestry-core/ref/org/apache/tapestry/corelib/components/FormInjector.html
