Error rendering the page

Classic Servoy

We randomly experienced the exception seen in the attached file in the server log.
I can’t understand where the problem comes from.
It makes customers not so happy because they’re blocked after the login…
Anybody knows more about that?

Thank you in advance.

The complete exception is :

org.apache.wicket.markup.MarkupException: Unable to find component with id 'sv_2A337275_BD2C_4A42_AF52_DB242419EE0A' in [MarkupContainer [Component id = sv_9F9A036D_A301_4344_B0B1_55F5D16F6025]]. This means that you declared wicket:id=sv_2A337275_BD2C_4A42_AF52_DB242419EE0A in your markup, but that you either did not add the component to your page at all, or that the hierarchy does not match.

don’t you have some other exception in the log file of servoy just before that?

Somehow the form is not setup correctly, this can also be if you use custom html in your form that is not completely correct html

The exception usually appear just after the login or during a tab opening (no matter which kind of tab). I say this cause we didn’t use custom html in tab creation but we changed the tab labels’ text generation…maybe this is the point altough it really seems to appear randomly for different clients during different operations!
One more thing, since we move to Servoy 7, the exception has not been raised already.
I’ll keep it under observation, thanks for your reply.
