Richfaces Migration issue: 3.2.x to 3.3.0 with datatable

[saxenahemant]

I have this html and backing bean which works in 3.2.x version but then, I am not sure what is the issue, the following thing wont work in 3.3.0:

xhtml:

<s:div style="width:950px; overflow-y:auto;">
 <rich:dataTable
 id="contCapacityList"
 value="#{resultTableDataModel.rows}"
 var="row"
 width="950"
 styleClass="resultList"
 rowClasses="first, second"
 rows="#{resultTableDataModel.resultTotal}"
 >


 <rich:columns
 value="#{resultTableDataModel.columns}"
 var="column"
 index="ind"
 sortBy="#{resultTableDataModel.findValue(row, column)}"
 rendered="#{resultTableDataModel.isSignificant(column)}"
 >

bean:

public boolean isSignificant(Column col) {
 boolean status = true;
 //Identity.instance().hasPermission("name", "action", null);
 if(col.getPropertyOfModel().equals(AdsTimeChunkCapacityModel.MODEL_PROPERTY_BOOKEDCOUNT)
 || col.getPropertyOfModel().equals(AdsTimeChunkCapacityModel.MODEL_PROPERTY_RESVCOUNT)
 ) {
 status = false;
 }
 else if(col.getPropertyOfModel().equals(AdsTimeChunkCapacityModel.MODEL_PROPERTY_AVAIL) && capacityOnlyMode) {
 // if UI is in show capacity only mode then there is no point showing Availability column
 status = false;
 }

 return status;
 }

Problem: I start getting null value in isSignificant() method for parameter "col" when i switch to 3.3.0 richfaces version.

Hello,

Yes. This was broken since 3.3.0 GA.
I added the issue: https://jira.jboss.org/jira/browse/RF-6267.
Rendered attribute that uses columns var for evaluation now returns null value...

But you can try workaround. Just return TRUE if passed paramer is null:

public boolean isSignificant(Column col) {
if (col == null) {
return true;
}
 boolean status = true;
 //Identity.instance().hasPermission("name", "action", null);
 if(col.getPropertyOfModel().equals(AdsTimeChunkCapacityModel.MODEL_PROPERTY_BOOKEDCOUNT)
 || col.getPropertyOfModel().equals(AdsTimeChunkCapacityModel.MODEL_PROPERTY_RESVCOUNT)
 ) {
 status = false;
 }
 else if(col.getPropertyOfModel().equals(AdsTimeChunkCapacityModel.MODEL_PROPERTY_AVAIL) && capacityOnlyMode) {
 // if UI is in show capacity only mode then there is no point showing Availability column
 status = false;
 }

 return status;
 }

P.S. If you will detect that sorting failed after RF migration, please assign id for columns as:

<rich:columns id="col#{ind}"
 value="#{resultTableDataModel.columns}"
 var="column" ....>

Best regards

Thanks for the prompt reply!!
Just to verification i can return true for every column but that is not workaround. Doing that will make all column visible. Anways, I will wait for the fix.
