T5: Equanda feature request
Don't know if this is a bad thing to ask about here, you just tell me if I
should take this business elsewhere... :)
In equanda-tapestry5 I discovered a very nice and useful component,
TextField, which updates a zone through the onchange event of a regular
textfield. This is excactly what I've been looking for, except that I need
to be able to specify an event other than "change". I've looked at the
source code, and it seems trivial to make the event a parameter. For now, I
will make this change in my own copy of this component, but I would love to
see this implemented in the equanda component!
Also, wouldn't it be cleaner to provide this component as a mixin? If
possible? I think I'll try that, I'll post the result here if I'm successful
:)
Regards
Inge

Either here or using the equanda-user mailing list. Both are fine.

Patches are always welcome.

I thinks there are specific reasons for not using a mixin, but can't
remember them now.
Though the example application does not show it, it is used in the rest
of equanda combined with the autocomplete mixin. I assume it had
something to do with that.
Kind regards,
Joachim

I will add a JIRA issue for adding a parameter in a link with javascript!

Ideally, the tapestry js should include a function to add a parameter in
a link. I have tried to cover all the link format cases I could think
of, but would not be surprised if it fails in certain cases. I you
encounter that, let me know.
Kind regards,

Re: T5: Equanda feature request

I just went ahead and created the mixin based on the equanda TextField
component, as far as I can see, it works nicely. The mixin lets any event on
any component update a zone. The only requirement is that the HTML element
has a "value" attribute. This limitation could easily be erased as well, I
guess. Right now I don't need to.
The only thing I see that is a little bit "dirty" is the way that equanda
puts the entered value into the link string. Is there any way to make it
easier to do this kind of thing natively in T5? Perhaps through a different
approach entirely?
Usage and source code:
TML:
<input t:type="textField" t:id="searchField" value="search" zone="list"
event="keypress" t:mixins="zoneUpdater"/>
JAVA:
- Provide a listener, in this case "onKeyPressFromSearchField", that returns
a Block the usual zone way.
