handling error in DataProvider
Hi
I have a panel (dashboard) with few data tables (widgets). When an error
appears in a data table model (data provider) I want to inform the user
about error, replacing the table component with a error panel.
It's possible to achieve this functionality in wicket or you can suggest
me another approach?

RequestCycle#onBeginRequest() may be a good place

Another question is where I can clean my flags with errors (I keep in
session a Map with widget's id as key and Exception as value)? I understand
that onAfterRender method is not a good candidate because it's called on
abort exception also.

the exception will be thrown as many times as there are tables. but
this exception does not fill in the stack trace so it should be fast.
profile the code and see where the time is.

The problem with RestartResponsePage approach is that when multiple data
tables (for example last 2 tables from 10) are in error I have a performance
problem. Is it true my observation?
Thanks,
Decebal

Hi igor,
You say that in IDataProvider.iterator(..) if an error occurs I throw a
RestartResponseException (probably with exception message as PageParameter).
But my panel has many data tables. How can I use your approach if errors
occur simultaneous in many data tables?
Thanks,
Decebal

you can set a flag on the page when an error occurs and throw a
RestartResponseException(page)
