CellTable - how to reload data?

[Magnus]

Hi,

I have a CellTable with an AsyncDataProvider who fetches portions of data from a database, as requested by the CellTable.

It's nice that CellTable keeps track of which portions are already loaded and that. However, there are events such as changing combobox which require reloading of the data.

For example, imagine a list containing cars and a combobox which allows to select a car manufacturer. When a car manufacturer is selected, the data within the list becomes invalid. But how can I tell the CellTable to reload its data?

Thanks
Magnus

Hi Magnus,
you can use setVisibleRangeAndClearData method. More information you can find here: http://google-web-toolkit.googlecode.com/svn/javadoc/2.1/com/google/gwt/user/cellview/client/AbstractHasData.html#setVisibleRangeAndClearData%28com.google.gwt.view.client.Range,%20boolean%29
