Hi!

My task is now that to create a parameter session, that stores paramater name and parameter value. The paramater value should be invisible based on the parameter name's pattern.
At the beginning, when the form loads it's working perfectly, but when I scroll, the first non-invisible value stucks in the invisible "empty" field.

For example:
Init:
P_param1 value1 (empty)
param2 value2

After scroll:
P_param1 value2
param2 value2

After rescroll:
P_param1 value1 (empty)
param2 value2

The code part for this:
before.display.object:
inputfield.visible("param.valu")
IF NOT visible.field AND param.name(1;2) = "P_" |#Parameter name starts with "P_"
THEN
inputfield.invisible("param.valu")
ENDIF
message( param.name & " - " & param.valu) |# For testing purpose
IF NOT is.field.invisible("param.valu")
THEN
display("param.valu")
ENDIF

Any suggestion?
Thank you in advance

With the following modification the "slide" effect disappeared, but the invisible method doesn't take any effect....

inputfield.visible("param.valu", actual.occ)
IF NOT visible.field AND param.name(1;2) = "P_"
THEN
disable.fields("param.valu", actual.occ) |#needed
inputfield.invisible("param.valu", actual.occ)
ENDIF

IF NOT is.field.invisible("param.valu")
THEN
enable.fields("param.valu", actual.occ) |#needed
inputfield.visible("param.valu", actual.occ)
ENDIF
