I think I described the problem rather stupid.
The problem is that you have to make panels if you want to show varying
FromComponents at the same template-place. Ie if you have a ListView which
either displays a CheckBox or TextField depending on the row you can not
just write:
<tr wicket:id="list"><span wicket:id="formComp"/></wicket:id>
and add the right FormComponent to the ListItem. But you need a panel to
wrap the FormComponent.
This is no herculaen task, but it bothered me to write these panels again,
when they are already used in different places. And than they also clutter
the respective apis.
So I just thought it would be good to have ie a TextField which can be
used directly in the ListView template like this:
<tr wicket:id="list">
<span wicket:id="comp">xxx</span>
</tr>
and than replaces it's tag body with <input type="textfield" name="xx">.
Html attributes like size would have to be set in Java code. To me this
does not make too much difference because otherwise to customize the
template you would have to subclass the Panel and provide a custom
template. And than you also have to somehow provide this new Panel to the
using component.
Mabe this all is against the wicket-way. Just a thought.

Hi,
Im just trying to make a special FromPanel where you just add
FormComponents and their labels and it will render those in a two column
table (similar to the Click Form).
Anyway as discussed before the problem is that you can not just set a
FromComponent on a div or span tag. The usual way around this is to make
specific Panels for each FormComponent which than has the FormComponents
specific html tag (ie <input type="text"> for a TextField).
Sorry, but I don't remember the problem. Could you please repeat it
for me. Tx. I know that FormComponent check the tag name they are
associated with and hence they can not be attached to <span> and
<div>. What is the problem with that?
This seems to be quite a bit of redundant work, because different parts
of
wicket (extensions.beanedit, extensions.data.table.filter,
wicket-contrib-data) have already their custom implementation of that
and
I think it is also quite useful in custom code if you go beyond 'basic'
forms where the exact set of FormComponents and layout is not known in
advance.
?!? It is probably because I don't know enough about the problem.
- redundant work because one panel per FormComponent => ok, understood
and what is useful?
With the current Panel aproach I also think that customizing the
html-tag-attributes for the FormComponent is a bit inconvinient
especially
if you need to do it from code and further different in each of the
use-cases.
Maybe for the FormComponents which have no children (TextField,
TextArea,CheckBox, DropDownChoice,ListChoice and ListMultipleChoice)
there
could be an overrideable property isRenderFullTag(). On true they would
than not check for the right tag, but render their full html replacing
what is in the template-html.
?!? "but render their full html replacing what is in the
template-html" What template html? you are not talking about the
markup, right?
Mabe they could also have a convinience
method like addAttribute(String name,String value), addAttribute(String
name,IModel model).
you don't like AttributeModifiers?
addAttribute => add(new AttributeModifier()
Sorry if these are stupid questions. I didn't follow all the
discussion about Forms.
