RecordList remove throws Error

[chodges]

Hello:

I'm having a problem using RecordList (latest build from 9/21/09.

When I call the RecordList.remove method I'm getting the following error;

Uncaught JavaScript exception [com.google.gwt.core.client.JavaScriptException: (TypeError): Object doesn't support this property or method
number: -2146827850
description: Object doesn't support this property or method
at com.smartgwt.client.data.RecordList.removeAt(Native Method)


Here's my code:

RecordList rl = _parentList.getRecordList();
					
int index = rl.findIndex("id",_currentRecord.getAttributeAsInt("id"));
					
if(index != -1)
{
	Record r = rl.removeAt(index);  //This line throws the error
												
	r.setAttribute("lastname", (String)_lastName.getValue());
	r.setAttribute("firstname", (String)_firstName.getValue());

	rl.addAt(r,index);
}

Ultimately I'm looking for a way to update a record in the list. If there's a better and supported way please let me know.

thanks!

Hi Chris,
I was able to reproduce the issue. This issue is with removeAt(..) and it needs to be fixed.

However there's a simpler way to do this. Simply call grid.updateData(record) after updating the attributes of the record in question. Your DataSource needs to have a PK defined.

Error in removeAt

I am having the same problem of removing and in addAt, I would put a specific record always on top of the list, and other records remain ordered, any solution?

if (getCategoryGrid().getRecordList() != null && !getCategoryGrid().getRecordList().isEmpty()) {

	int index = getCategoryGrid().getRecordList().findIndex(CategoryAttrib.ID_CATEGORIA, 1);

	RecordList list = getCategoryGrid().getRecordList();

	if (index > 0) {
		Record record = list.get(index);
		if (record != null) {
			getCategoryGrid().getRecordList().removeAt(index);
			getCategoryGrid().getRecordList().addAt(record, 0);
		}
	}

}
