How many times do you see this error page while building an Apex page?
ERR-1777: Page 1 provided no page to branch to.To avoid that, I have a habit of creating an unconditional branch back to the same page in every page I build, with a sequence number higher than all the conditional branches. If I then add new conditional branches I have to ensure that I change the default sequence to a lower value.
Please report this error to your application administrator.
A long time ago (in 2007) in this OTN forum thread I asked:
"I don't understand why we have to create these unconditional branches at all - why can't the default behaviour be to branch back to the same page if no other branch is taken? When is the "no page to branch to" error ever useful?!"In Apex 4.0, this annoyance finally disappears:
"When no branches have been defined then branch page back to itself rather than showing an error."
Sometimes the little things make all the difference!
