Hello, The problem was solved by the advice I got from a wiquery developer.
He said it was a common problem which happens when double ajax requests are issued where the first ajax request rewrite a component, and the next one refer to it. I solved the problem by preventing it by using the technique introduced at the following link, and it works. http://wicketinaction.com/2008/12/preventing-double-ajax-requests-in-3-lines-of-code/ Thanks, Takeo Hosomi On Thu, Dec 9, 2010 at 4:56 PM, Takeo Hosomi <[email protected]> wrote: > I attached it to a JIRA. > https://issues.apache.org/jira/browse/WICKET-3248 > > Thanks, > Takeo Hosomi > > On Thu, Dec 9, 2010 at 4:12 PM, Jeremy Thomerson > <[email protected]> wrote: >> Attach the zip of the quickstart to a JIRA. >> >> Jeremy Thomerson >> http://wickettraining.com >> -- sent from my "smart" phone, so please excuse spelling, formatting, or >> compiler errors >> >> On Dec 9, 2010 4:15 PM, "Takeo Hosomi" <[email protected]> wrote: >> >> Hello, >> >> I have the same issue which is discussed in the following link: >> http://apache-wicket.1842946.n4.nabble.com/WicketRuntimeException-component-not-found-on-page-td3055902.html >> >> I made a quickstart to reproduce it.
