posting.submit() causes error because it is read only
|
|
| James Coleman 2006-03-18, 3:18 am |
| I am trying to create a template that basically allows a user to edit a class
in which I then serialize into xml and then store into the xmlhtmlplaceholder
of a cms template. When I try to do a posting.submit, I get an error thrown
saying that the object is readonly (even though posting.cansubmit is true).
Any help would be appreciated.

| Thanks Stefan for the response. Sorry about the mulitiple postings, when I
was submitting I was getting an error and I didn't realize my post was making
its way in.
I guess I don't know what object and property you want me to check to see if
I am in "update".
The WebAuthorContext.Current.Mode at the time of the posting.submit() is
WebAuthorContextMode.AuthoringReedit.
I will continue to poke around and try and figure it out myself because I am
assuming you take the weekend off.

| Okay, it looks like the CmsHttpContext.Current.Mode is equal to Unpublished
when the page loads from by own save button control.
When I click the 'Save' from the defaultconsole.ascx then the
CmsHttpContext.Current.Mode is in Update mode. So I either need to set the
CmsHttpContext.Current.Mode = to Update (which is readonly - so I don't know
how to do that) or I need to find out how I can get my own code to run when
the 'Save' within the defaultconsole.ascx is clicked.
Any ideas/help would be greatly appreciated.

| Hi James,
the correct way to do this is to implement a workflow event.
Here e.Context will be in Update mode.
Cheers,
Stefan
