hi, we were thinking that we could have an application variable that stores the state of the data, for example if it has not changed then it is set to 'no change', else if it is processing a request then it would be set to 'processing', and if it has finished processing and no errors occurred then it would be set to 'changed'.
then if another user tries to change information then it checks the state if it is 'processing' then they will be asked to wait, and if it is set to 'changed' then they have to click a button that reloads the data before they save, as otherwise there may be 2 people trying to change the same bit of data and would result in data inconsistency. it will keep track of whether each user has reloaded the data by storing a variable in their session scope and set to either 'reload required' or 'reloaded' just wondering what you think of this scenario or whether others have achieved this in a more simple way. thanks richard >You can not do this with basic HTTP/HTML/AJAX level technology.
