Cant get rid of "duplicate Id for a component "

satyakatti Oct 21, 2010 8:13 AM

Hi All,

I am not sure how and where the IDs of components are duplicated. But I do set the IDs manually and eventhen I get this exception.

Below is the code of my xhtml which uses a Extended DataTable.

Can you let me know if I am doing something wrong in the code?

1. Re: Cant get rid of "duplicate Id for a component "

satyakatti Oct 22, 2010 4:11 AM (in response to satyakatti)

I was able to solve the Duplicate ID problem by removing the binding property and implement the row selection by below code:

Iterator<Object> iterator = getSelection().getKeys();
        ChannelAttributes ch = null;
         while (iterator.hasNext()) {
            Object selectedRowNum = iterator.next();
            ch = channelsList.get((Integer)selectedRowNum);
        }

But with this I face another new problem i.e selection of table row is wrong when data is filtered.

I mean, if user filters the table data based on a column and selects a row (based on the filter result), correct row is not selected.
Ex: If I select 1st row after filter, the selected row will be 1st row which was before filter.

Is it possible to get correct row from the filtered result without using binding property of the ExtendedDataTable?

Regards,
Satya

original problem caused by binding. it was session scoped I guess. It's one of the most known problems in JSF (in our FAQ also)

And the last problem also really easy to solve. You using selection by just index - so it works as it should, but you need to use rowKeys. download richfaces demo - extendedDataTable sample has it implemented using simple with realy simple dataProvider.
