Hi Hani,

to find the optimal solution for your problem it whould be helpful tohave a screenshot of your app.

The question is: is the number of links in one column limited? Are thelinks mostly the same, or are they completely independent?When we have limited links, we can use static links with renderedattributes and we don't have to create lots of components in each row.


Regards,

Udo

Hi Volker,

By component binding i used actually your tip for using rendered attribut 
(thank you!)
After creating the main panel and his children panels for each row of the 
sheet, i've
defined the rendered attribut of the children panels with:

ComponentUtil.setBooleanProperty(childPanel /* the i child panel */, 
TobagoConstants.ATTR_RENDERED, "#{" + sheetVar
                                                                                         
+ ".index == "
                                                                                
         + item.getIndex() /* for i child panel */
                                                                                         
+ "}");

So that the first panel will be in rendered in the first row and the rest of 
panels will be disabled and etc.
It works fine, but i need a better solution. The jstl way works also, but all 
panels will be displayed in each row of sheet.
I didn't think about a new implementation of the UIPanel, i will try this one 
now.


Thank you

Regards,
Hani

Hi,

as Udo wrote, you can't use jstl inside tc:sheet!
Or to be more precise: the var param of tc:sheet is not available when
jstl iterates, because jstl evaluates before tobago starts renderring.

I also can't imagine how you do this with component binding, because
this is also done before rendering starts. Can you explain how you do
this?

But there is a way to solve this, you need binding to a extended
UIPanel implementation which drops and recreates children depending on
sheets var in each process* method.

     Volker

Betreff: AW: [Tobago] foreach in c:sheet

Hello Udo,


I want to add a dynamic panel to a column, which has many elements for each row 
in the sheet,
that means the content of the panel for each row is different (like sheet in 
sheet).
I could do it with programming of whole panel in java and binding it in the 
jsp, but i am looking now for a different way.

I've tried to use jstl, but it doesn`t work to render the right dynamic panel 
for right row:


<tc:column sortable="false" align="left">

    <tc:panel id="headPanel">
        <c:forEach items="${myBean.list}" var="x" varStatus="status1">
            <tc:panel id="subPanel${x.nr}" rendered="${status1.index} == 
${x.nr}">
                <c:forEach items="${x.subList}" var="w" varStatus="status2">
                    <tc:link image="${w.iconUrl}" id="link_${x.nr}_${w.nr}" />
                </c:forEach>
            </tc:panel>
        </c:forEach>
    </tc:panel>

</tc:column>

I've used jstl 1.1.

Thank you.

Hello Hani,

I've never tried to use<c:set>, so I have no experience with that tag.

Your code will not work, because the content inside of the<tc:sheet>
will be visited only one time.
The JSTL Tag needs to be called in each row to make it work.

Mixing JSTL and JSF and use of iterators have some drawbacks. This
depends also on the version of the libraries. Which version you are using?

You may try to make your data accessible via the var-attribute of the sheet:

<tc:sheet var="row" ...>
...
        <tc:column
                <tc:out  value="#{row.subListAsString}" />
        </tc:column>
...
</tc:sheet>


Regards,

Udo

Hello,

We want to visualize some dynamic content within a column for each row
of sheet with jstl.


We tried to incrment a variable (defined outside of the tc:sheet
element)  with:<c:set var="counter" value="${counter + 1}" />    to get
the row index, but it doesn't work.

Jsp:

<tc:sheet ..>

...
       <tc:column

               <c:set var="counter" value="${counter + 1}" />

               <c:forEach  items="${bean.itmesList[counter].subList}"
var="w" varStatus="status">
                               <tc:out  value="${w}" />
               </c:forEach>

       </tc:column>
...

</tc:sheet>




Is it possible and how?


Thank you.
