Sounds like a rules issue to me. headerComponent is a key that is recognized by the templates.
If you want to change the header, why don't you just use the key that exists? If you need the new key "headerInstructionComponentName", make sure you have a fall back rule somewhere that resolves to true (i.e. if you are using this key in the templates, the template has to find a value for it, even it is a blank component or something - this is why I suggest using the default key). Take a look at the rules for headerComponent to see how the pros do it. d On 2013-03-13, at 11:33 AM, Theodore Petrosky <[email protected]> wrote: > the issue was. when I clicked the tab (takes you to the list page) the > headerInstructionComponentName componentName was set in the method that fires > when you click the tab. > > However if you were on the Query page and clicked the submit button, the key > was not set so I got the error. > > Finally, I took the assignment out of the list method and created a rule: > > 100 : pageConfiguration like '*ProjectWorkOrder' => > headerInstructionComponentName = "ProjectWorkOrderInstructions" [Assignment] > > and this is working in all cases. > > Is there something betterer? > > > > --- On Wed, 3/13/13, David Holt <[email protected]> wrote: > >> From: David Holt <[email protected]> >> Subject: Re: need rule help >> To: "Theodore Petrosky" <[email protected]> >> Cc: "WebObjects Development" <[email protected]> >> Date: Wednesday, March 13, 2013, 2:05 PM >> If you expect the submit button to >> take you to a list page, why are you setting the header on >> the query page? >> >> >> On 2013-03-13, at 10:50 AM, Theodore Petrosky <[email protected]> >> wrote: >> >>> I think I am finally understanding the issue. in my d2w >> app, when I click the tab for a 'ListAgenda' page, I fire a >> method that ultimately does: >>> >>> ((D2WPage) >> lpi).d2wContext().takeValueForKey("AgendaInstructions", >> "headerInstructionComponentName"); >>> >>> but when I click the submit button on the query page, >> there is no assignment of this key.
