Re: WritePro expression undefined
David,
eval is a project method that will execute a PROCESS 4D TAGS. I am pretty sure
Erick provided an explanation to what that method does.

Hi David, I also include methods in 4D Write documents that do queries and other operations that do not return a value. I’ve never put raw 4D commands in a 4D Write expression, but many places are methods without $0 defined. I wonder if 4D Write Pro will do the same thing with methods that do not return a value? Have you tested this? And I agree with you that 4D Write Pro should not make this change in how it works compared to the 4D Write Plugin. It makes no sense. It should changed to work as it did before. A bug report/feature request needs to be submitted so that they can change this behavior immediately and you can then get a hotfix or nightly build that has this change. I’m guessing this was just an oversight in the 4D Write Pro implementation that the team never considered. It should be fixed.

RE: WritePro expression undefined
Add, 4D Write expressions did not require a value to be returned, so it was acceptable to have embedded Query, Create Set, Intersection, Union, Use Set, Selection to Array, etc…, commands in the 4D Write document. Converted to WritePro, the same expressions return “Undefined”. It is a change in behavior that requires editing 1000’s of documents. And WritePro does not provide an easy way to replace those expressions with a method call that will not return “Undefined”.

Re: WritePro expression undefined
There is no such command SET ALLOWED COMMANDS, only SET ALLOWED METHODS which only works on methods. If you allow users to enter "QUERY" then they can also enter DELETE SELECTION.

RE: WritePro expression undefined
John, We opened a case with 4D. WritePro optionally displays expressions, or their calculated values. We may have to parse the converted WritePro objects to replace queryies with a call formatted like: Query_ (->[Student];->[Student]AccountNo;"=";->[Account]AccountNo) …which does… QUERY($Table_p->;$Field_p->;$Operator_t;$Value_p->) It’s a bug. WritePro should not show “Undefined” as the result of a embedded query expression. SET ALLOWED COMMANDS should also work for 4D commands, since if a user is allowed to enter expressions, than those expressions should be restrictable.

You lose that visibility by embedding queries directly in 4D Write documents. Maybe that does not work if you have end users writing their own queries for 4D Write. That seems dangerous to me.

RE: WritePro expression undefined
John, WritePro documents may contain references to [Table]Field, which requires that the record be present during printing, which may require QUERY commands. The embedded QUERY commands work, execute properly in WritePro. But in place of the embedded expression is the value “Undefined”. We have hundreds of converted documents with queries in them that worked correctly in 4D Write. There they executed and did not display “Undefined” in the 4D Write document. These should not have to be wrapped commands to work without an “Undefined” appearing in the WritePro document. This in new and apparently wrong behavior in WritePro. If this is not an error in WritePro, and if it is the intended operation of WritePro, then it is a warning to everyone converting from 4D Write documents.
