[Trinidad] infinite loop when trying to set selected row / set row index

[th...@mvv.de]

While trying to fix this (http://www.nabble.com/-Trinidad--how-to-add-default-selection-for-Table-td16698321.html) I found a strange behaviour that looks like a bug.
The table is defined like this:
<tr:table value="#{myBean.billingAdresses}" var="address" rowSelection="single" binding="#{myBean.addressTable}" > 
The method billingAddresses() returns a Collection of BillingAddress-objects. The row displaying a certain object should be pre-selected when the table is displayed. So, in the backing bean, there are a number of called methods to find the right RowKey and to create the RowKeySet to set to the table using UIXTable.setSelectedRowKeys(). This are the used methods:

	public List<BillingAddress> getBillingAdresses(){
		addressList = myData.getBillingAdresses(getUser(), getJcoClient());
		addressTable.setSelectedRowKeys(getSelectedRowKeys());
		
		return addressList;
	}
	
	public RowKeySet getSelectedRowKeys(){
		RowKeySet selectedRows = getMatchingRowKeys(currentAddress, addressTable);
		return selectedRows;
	}

	public RowKeySet getMatchingRowKeys(BillingAddress sample, CoreTable table){
		RowKeySet keySet = new RowKeySetImpl();
		int rows = table.getRows();
		for(int i=1;i<rows;i++){
			table.setRowIndex(i);	// <-- This is where the JVM jumps back
			BillingAddress rowAddress = (BillingAddress)table.getRowData();
			if(rowAddress == sample)
				keySet.add(table.getRowKey());
		}
		return keySet;
	}

The problem emerges when debugging step by step through this. Everything is fine until getMatchingRowKeys(...) is called. In the line marked with // <!-- the debugger jumps back to the first line of getBillingAdresses(...) resulting in an infinite loop.

My questions are:
1) Is there another way to get the apropriate RowKeys and set them to the table
2) Should I report this to JIRA or is there an error in my code that keeps hidden from my eyes?

Please note also this posting http://markmail.org/message/mku5h24ofwi2gnrd#query:how%20to%20RowKEySet+page:1+mid:mku5h24ofwi2gnrd+state:results as it looks like dealing with the same problem.

Thanks,
