Converted to Active4D 4.0rc4 last week and had very few problems.
Thought I'd point out a couple in case you have not made the switch.
RowSet: Version v3.1.0 build 5 of RowSet.a4L, NewFromData had the
row delimiter and column delimiter switched in the parameter list.
Had a few text process variables defined in compiler_web that are
used if the 4D method was called from both 4D and Active4D. In 3.0,
I'd assign a value to this process variable that comes in from a form
variable, and then call the routine. This worked fine in 3.0. Under
4.0 I'd get an error:
Job_StatusView_t := $stat
Cannot change the type of a 4D variable in a compiled database.
$stat comes from the form variable and is defined as string(255).
Though you could assign a string variable to a text variable, but not
in 4.0. I just created a local text variable c_text($tstat) and
assigned $stat to it, then assigned it to the process variable. Seems
a little too strong typing since Active4D assigns all form variables
as string if they are under 255 characters. Again, only had a few of
those, and I think it caught all of them.
Other then those two minor gotchas, it would of been smooth sailing
if I didn't screw up my grep replace of changing
'set session("xxx";yyy)' to 'session{"xxx"} := yyy' [needed to
go to last ) after ;, not first ) ]
