ListGridRecord can not be cast to TreeNode about smartgwt

[GoogleCodeExporter]

We are not aware of any regressions in this area.
If you would like this investigated, please include a ready-to-run standalone 
test case (typically a simple EntryPoint class) which will reproduce the issue 
as well as including full details:
- which exact SmartGWT version you're seeing the problem in (and be sure to 
test the most recent nightly build)
- what configuration (Browser, OS, GWT version) the problem manifests in
- Hosted mode only, or also in compiled mode

Thanks

Hi,

I am facing similar kind of issue. 
We have client only data source enabled. We have extended ListGridRecord to our 
specialized class and adding this specialized class records to datasource.
Inside cellformatter, we are getting exception when we are trying to cast to 
our specialized class.

E.G:
Our specialized class name is: FileDescriptorGridRecord which extends 
ListGridRecord.
Inside Cellformatter:
setCellFormatter(new CellFormatter() {
        @Override
    public String format(Object value, ListGridRecord record,           int rowNum, int colNum) {
            record.getAttributes();
            FileDescriptorGridRecord fileRecord=(FileDescriptorGridRecord) record;

At this point we are getting excpetion saying:
20:01:13.450 [ERROR] [cm] Uncaught exception escaped

java.lang.ClassCastException: com.smartgwt.client.widgets.grid.ListGridRecord 
cannot be cast to com.altair.cm.rfb.client.data.FileDescriptorGridRecord at 
com.altair.cm.rfb.client.FileDescriptorGrid$2.format(FileDescriptorGrid.java:255
)

This is happening only after upgrading from 2.3 to 4.1.

Could you please let me know where I am going wrong?

Thanks
Viswanath
