Unfortunately I think I might have found a bug in 5.05. I always tend to assume that I’m doing something wrong when something doesn’t work, but in this case I’m getting distinctly different results between version 5.01 and 5.05 versions of the webserver templates, which makes me think that Bruce might have changed something.
I’ve upgraded to 5.05 as it appears to fix a problem that I was having with trying to display a popup browse (I’ve embedded a browse into a popup form, and that seems to work ok with this version). Unfortunately I’ve just found that every time I try to insert a new record in to one of my SQL tables I get a “Creates Duplicate Key” error on my primary key. Exactly the same app, and the same database with 5.01 works fine and allows the insert without the error.
A bit of background: I’m using MSSQL 2005/2008. I have a JOBID column that is an SQL identity field. I have a Primary Key on that field which is also my unchanging key in my netwebform. I have the EmulateAutoNumKey value set to 1 in my dictionary.
I have child browses that I need to populate during the insert of my parent record, so I have both the “prime Auto Inc if necessary” and “Prime Auto Inc even if not necessary” ticked, and I don’t have the “Ignore Key being not unique” ticked, although this doesn’t seem to have any effect either way.
I can’t see any difference between the generated code in the Check For Duplicates routine, with either template, so I’m not quite sure where to go now. Has anyone else seen this problem?
TIA,
Neil Porter

Hi Niel,
I've fixed an auto-increment bug in 5.06, so as soon as I have that up I'll let you know.
I'm not sure if it's the same thing, but it's a good place to start.
cheers

In the meantime you can test the fix to see if it works for you;
In NetWEb.Tpw, find the line
p_web.formsettings.action = Loc:Act
replace that 1 line with the following 5 lines;
if p_web.GetSessionValue('%Procedure:Primed') = 1
p_web.formsettings.action = Net:ChangeRecord
Else
p_web.formsettings.action = Loc:Act
End
Let me know.
cheers

Hi Bruce,
I've made the change to the template, and recompilled. I'm afraid that it doesn't seem to have fixed error.
Regards,
Neil

HI Bruce,
I've done some further digging now, and you are quite correct, that it is that section from netweb.tpw that seems to be causing the problem. Even with your suggested modification i still get an error, but if I remove the whole section in red it seems to work fine.
If p_web.Formstate = ''
p_web.formsettings.file = 'Jobs'
p_web.formsettings.key = 'JOB:PK_Jobs'
clear(p_web.formsettings.FieldName)
p_web.formsettings.recordid[1] = p_web.RestoreValue('JOB:JobID')
p_web.formsettings.FieldName[1] = 'JOB:JobID'
IF p_web.GetSessionValue('UpdateJobs:Prime') = 1
p_web.formsettings.action = Net:ChangeRecord
ELSE
p_web.formsettings.action = Loc:Act
END
If p_web.GetValue('_parentPage') <> ''
p_web.formsettings.parentpage = p_web.GetValue('_parentPage')
else
p_web.formsettings.parentpage = 'UpdateJobs'
end
p_web.formsettings.proc = 'UpdateJobs'
p_web.FormState = p_web.AddSettings()
end
if loc:viewonly and p_web.IfExistsValue('LookupField')
packet = clip(packet) & p_web.CreateInput('hidden','LookupField',p_web.GetValue('LookupField')) & '<13,10>'
end
packet = clip(packet) & p_web.CreateInput('hidden','FormState',p_web.FormState) & '<13,10>'
My only concern, is that in removing these lines, it may impact somewhere else, that isn't immediately obvious to me.
Regards,
Neil.

I don't think you can remove that whole block. If p_web.formsettings.action is not set, then nothing will happen when you click on the Save Button (in some/many cases.)
I think the next step is if you can put some example together for me.
cheers
Bruce
