[TRINIDAD] Dynamic column groups
Hi all,
I have a number of counters that I want to show as nested columns. This
will look something like this:
| | Counters |
| Date | AA | BB | CC | DD | EE |
|-------------|------------------------------ |
| 22/06/2008 | 0 | 20 | 10 | 0 | 10 |
| 22/06/2008 | 0 | 21 | 12 | 0 | 12 |
| 23/06/2008 | 2 | 23 | 15 | 10 | 10 |
...
In my backing bean I have a List of Objects. For all objects in my list I
want to show a column , but how do I have to dynamically create group
columns? I already tried this:
<tr:table binding="#{backingBean.overviewTable}"
value="#{backingBean.dataModel}" var="row">
<tr:column headerText="Date">
<tr:outputText value="#{row.date}" converter="DateConverter"/>
</tr:column>
<tr:column headerText="Counters">
<c:forEach items="#{row.counters}" var="counter">
<tr:column headerText="#{counter.type.id}">
<tr:outputText value="#{counter.valueString}"/>
</c:column>
</tr:forEach>
</tr:column>
</tr:table>
The result of the code above, is an empty column under "Counters". Can't I
use c:forEach? Or is there something else wrong?
If I use tr:iterator instead of c:forEach, I get an
IndexOutOfBoundsException (on position 5). But this is something I don't
get. This iterator isn't supposed to iterate out of the bounds... Or is
it?
Using tr:forEach isn't a solution either. This results in an exception
(noClassDefFoundError javax/servlet/jsp/jstl/core/IndexedValueExpression )
because it needs the jstl 1.2 library and on this moment I'm only allowed to
use jstl 1.1.2...
Hope someone can help me (or point me to the correct direction) because I'm
searching a couple of days now... Wish there was an easy solution!
Joris

I think one option is to use the <trh:xxx> components, like
layoutTable/cellFormat and use forEach/iterate
to generate those columns.

Joris,
I am using the Tomahawk component, <t:columns>, inside a <t:dataTable>.
The table is inside a Trinidad component. I do not know the answer to
you question.
I suggest you pose the question in a new post with an appropriate subject.

t:dataTable and t:columns are Tomahawk components, not Tobago ones.
http://myfaces.apache.org/tomahawk/extDataTable.html
Some of what it is available from varStatus is available on the Tomahawk table.
For example, rowIndexVar for varStatus's index.

Hi Joris,
You could use the backing bean to dynamically create the columns. It had helped me in my project.
In the backing bean you could create a method
createColumn(int numOfCols){
List<UiComponent> tableChildList = table.getChildren();
for(int i=0;i<numOfCols;i++){
CoreColumn newCol= new CoreColumn();
List colChildList = newCol.getChildren();
//set HeaderText for new col
CoreOutputText newText = new CoreOutputText();
// setValue binding of newText
colChildList.add(newText);
tableChildList.add(newCol);
}
}
cheers......

Thanks Paul,
this seems to be what I need... However, I implemented it now using a
trinidad table. The Trinidad table has an attribute varStatus. Is there
something simular in the Tobago dataTable?

Joris,
I am doing something similar using <t:columns>. Their is documentation
