Stanislas RENAN commented on MYFACES-1417:
------------------------------------------
workaround : use JSTL tags
<c:choose>
<c:when test="${myCondition}">
<c:set var="columnClassesForDataTable"
value=",,chiffres,chiffres,chiffres,chiffres,chiffres,,,,,,," />
</c:when>
<c:otherwise>
<c:set var="columnClassesForDataTable"
value=",,chiffres,chiffres,,,,,," />
</c:otherwise>
</c:choose>
and use it in your dataTable :
columnClasses="#{columnClassesForDataTable}"
> Error of css styling of h:dataTable -> h:column when rendered attribute is
> used and the number of columns rendered depends on logical criteria

> Key: MYFACES-1417
> URL: https://issues.apache.org/jira/browse/MYFACES-1417
> Project: MyFaces Core
> Issue Type: Bug
> Affects Versions: 1.1.4
> Environment: I used MyFaces Core 1.1.4 and the Tomahawk Snapshot
> 1.1.5 (20th September 2006)
> Reporter: Martin Kuhn
> Attachments: JSFErrorTest.zip

>
> I've table with 9 colums. When a special condition is true I want to display
> only 8 columns. (the 4th column should be hidden). This "magic" is realized
> with <t:column rendered="{#backingBean.condition}" ..>
> For the style of the columns I use the columnClasses attribute of the
> datatable. Because of the variable number of the column's I serve the
> columnClasses attribute with a backing bean <h:dataTable
> columnClasses="#{backingBean.columnClasses}" .../>
> When the number of the columns is equal to the maximum numbers the styling
> is o.k. (every column got the right class attribute value).
> When the number of columns is less than the maximum numbers the styling of
> the columns is wrong. (The column style attribute is wrong )
> I checked the return value of the backing bean for the columnClasses
> attribute and the value is o.k.
> I got this values for the columnClasses Attributte when I have to render 9
> columns:
>
> tableSelectionColumn,tarifBezeichnung,date,standardTableColumnCentered,standardTableColumnCentered,standardTableColumnCentered,tarifKurzBez,praemie,standardTableColumnCentered
> when I have to render 8 columns:
>
> tableSelectionColumn,tarifBezeichnung,date,standardTableColumnCentered,standardTableColumnCentered,tarifKurzBez,praemie,standardTableColumnCentered
> I the case when only 8 columns should be rendered for example the 6th column
> is rendered with the class praemie. But this class is on 7th position in the
> columnClasses value.
> And the same code worked with version 1.1.1 correct.
> I've a little example which shows this bug
