Error flushing page

[Anton Komratov]

I’m using wicket-1.4.rc4 with Geronimo 2.1.4 (tomcat 6, java ee 5) and
have got the following exception:

FeedbackIndicator doesn't work inside RefreshingView

[Anton Komratov]

I'm using RefreshingView to show and edit data. I put MinimumValidator to
the TextField in RefreshingView (in method populateItem()).Also I put
FeedbackIndicator for this TextField in RefreshingView (also in method
populateItem()).

MinimumValidator works fine - I'm getting error messages at the
FeedbackPanel. But FeedbackIndicator doesn't work - no any red asterics in
case of invalid value in TextField.
Others FeedbackIndicators at the same pages (for others TextFields outside
of the RefreshingView) work fine.

Any solutions? (I'm using wicket 1.4rc4).

/// Java code fragment:

@Override
*protected void populateItem(final Item item)* {
item.add(new Label(name));
item.add(new Label(surname));
item.add(new Label(city.name));

TextField tfam = new TextField(amount);
tfam.add(new MinimumValidator(1));
item.add(tfam);

*FormComponentFeedbackIndicator amountFlag =
new FormComponentFeedbackIndicator (amountFlag);*
* **amountFlag.setIndicatorFor(tfam);*
*item.add(amountFlag); * }
///
