[Trinidad] custom renderer / use facet as template

i wrote a custom renderer for selectmany-components to render selectitems as user-defined components instead of checkboxes. actually this renderer uses a facet "template" to get the components, that should be renedered:

<ck:selectManyComps styleClass="imageSelection">
  <f:facet name="template">
    <tr:panelGroupLayout layout="vertical">
      <tr:icon name="sound"/>
      <tr:outputText value="#{label}"/>
    </tr:panelGroupLayout>
  </f:facet>
  <s:selectItems value="#{images}" var="i" label="#{i.url}" />
</ck:selectManyComps>

the problem here is that components inside the facet are already associated to an identifier and hence this ids are duplicated...

so, i'd like to ask:
- how can i reassign those component-ids?
- is there a better way to pass template-text to a renderer?

thanks 
christian

Re: Dynamic forms with JSF

Posted by Richard Yee <ry...@cruzio.com>.
Martin,
Thanks for the reply. Unfortunately, I don't know which half of the 
emails you are getting...
At the moment, we can't use 1.2 b/c we need to run on an Oracle OAS 
10.1.3.1 AppServer. I will check out Facelets. We are currently using 
the ADF af:table tag. We will be changing over to use Trinidad.

I have found a partial workaround for the problem. If I don't bind the 
components and instead use EL expressions for the attributes I get 
around the 'PropertyNotFoundException : error setting property in bean 
type null' problem.
My current problem is that if I use a af:inputDate with a af:chooseDate 
and link them with the chooseId and id attributes, I get a 
TrRequestQueue.getInstance is not a function JavaScript error. The error 
happens when there are multiple forms (more than one plan). I tried to 
fix this by dynamically generating the id for the chooseDate but found 
that this is not allowed from the post, "RE: Dynamic id's with Partial 
Page Rendering" from 03/04/07.

Do you think that the "TrRequestQueue.getInstance is not a function' is 
a bug or is using multiple inputDates and chooseDates in a tr:forEach 
not a supported usage?

I am using Trinidad 1.0.2

Thanks,

Richard

Hi Richard,

I only seem to see half of your mails, but here some possible ways to
get to such functionality easily:

- use JSF 1.2 - c:forEach should work
- use Facelets - c:forEach should work
- Tomahawk t:dataList or Facelets ui:repeat or Standard table and
Tomahawk Sandbox s:selectOneRow
- Trinidad tr:table (has automatic selection features)

regards,

Martin

Dynamic forms with JSF

Posted by Richard Yee <ry...@cruzio.com>.
Is it possible to have a dynamic number of forms in a JSF page? I would 
like to have a forEach tag in my page that iterates over a list of 
objects that contain a list if items to display in a multiselect table 
and some UI components that will get updated based on the rows that get 
selected.

I have seen other postings that seem to indicate that UI components 
cannot be inside a forEach tag and use the variable from the var attribute.

Is there any way to do this?

Ex.

Plan A
==============================
|    |  Name  |  Association |
-----+--------+---------------
| [] |   aaa  |     XYZ      |
-----+--------+---------------
| [] |   bbb  |     BBB      |
-----+--------+---------------
| [] |   ccc  |     CCC      |
-------------------------------------------------

SelectOneChoice

Checkbox

SelectOneChoice


Plan B
==============================
|    |  Name  |  Association |
-----+--------+---------------
| [] |   aaa  |     XYZ      |
-----+--------+---------------
| [] |   bbb  |     BBB      |
-----+--------+---------------
| [] |   ccc  |     CCC      |
-------------------------------------------------


SelectOneChoice

Checkbox

SelectOneChoice


...... possibly more Plans...
