Re[2]: How solve such problem?
Hello Harish,
Because pageBeginRender isn't invoked in such case:
public void homeFormSubmit(IRequestCycle cycle) {
final String orgName = ((Visit) getVisit()).getOrganization().getName();
log.info("Organization name: " + orgName);
if (orgName != null && orgName.trim().compareTo("") != 0) {
// go to page with list of similar organization
cycle.activate(CompanySelection.PAGE_NAME);
}
}
and also it's invoked before any setXXX methods have done.

Re: How solve such problem?
Posted by Harish Krishnaswamy <hk...@comcast.net>.
pageBeginRender() is invoked twice in a request cycle, once after the
Page is submitted (during rewind) and again just before the Page is
rendered. The second invocation is after all the setXs have been
invoked. You may distinguish the two invocations by calling the
IRequestCycle.isRewinding() method. Hope this helps.
