when validating do like this.

in pai.

field field1 module validate.

do your validating in the module validate.

if you have multiple fields that are to be input enabled even when you get the errro message, then do like this

chain.

field field1.

field field2.

module validate.

endchain.

hI,

PAI.

Field Sflight-carrid values (‘LH’).

Field Sflight-connid values (‘0400’ ‘0500’).

In this case if the user enters only carrid wrong, then this particular field is enabled and rest of the fields are disabled for user to input. Many times if the user enters wrong value for one field, then you might want to give option to user to enter all the fields, which is not possible by using Field statement only. This functionality can be achieved by CHAIN – ENDCHAIN.

Syntax

Chain.

Field sflight-carrid value (‘LH’).

Field sflight-connid values (between ‘200’ and ‘500’).

Endchain.

Field sflight-price values (‘100’ ‘1000’).

In this case, if the user enters wrong value only for carrid, both the fields i.e. carrid and connid are enabled as they are grouped together in the Chain statement. The field price will be disabled for input. Usually, logically related fields are grouped together with Chain-Endchain statement.

Regards,

Sruthi
