I am using a webservice through an action in a field to retrieve some aditional data as well as validate the user input. The validation is done by storing in a instance the validation status and make the input field to check that the code is not present to be valid. This works correctly as long as I don't try to use a repeated grid. When a repeated grid is used the same instance is used for all the repeated fields. The webservice data is loaded correctly independendtly, but the validation is shared between all of them. How can I adjust the code to work properly in repeated grids?

What version of Orbeon Forms are you using? Since 4.5, control resolution follows repeats in actions, so the result from your service should only change the
nameandaddressof the current iteration, i.e. the one in which theuserIdchanged and triggered the action to run, which seems to be what you are looking for.
