Re: How can one REDRAW a SUBFORM that uses a OBJECT as its 'variable or expression'?

[Chris Belanger via 4D_Tech]

Thank you, Lahav. Worked.

Still don’t understand why REDRAW( ) doesn’t get a (*; OBJECT NAME) syntax 
though …

(But your solution is simple enough)

Re: Trouble with Comment Blocks v18

What build version are you using? This was supposed to be fixed after version 
18.246179.

[lists via 4D_Tech]

All you need to do is to assign the entity selection object to itself to 
trigger an update, as in

Form.my_Entity_List:= Form.my_Entity_List

Sorry for not including that detail. It is an entity-selection listBox. I had 
initially written more detail about my issue and decided perhaps it was too 
verbose (a bad tendency of mine).
It has the same ‘REDRAW( )’ issue as the subform that contains it — no way to 
indicate the object. Since there is no REDRAW ( * ; objectName ) syntax.

You were not hallucinating.  When a field name is changed in the structure, the

Ok. I guess I was hallucinating or something. It works today with one

names…..), the new field name doesn’t work in an orda query. I get this error:

The "Account_Name" attribute cannot be found in The "Deposits" datastore class

How can one REDRAW a SUBFORM that uses a OBJECT as its 'variable or expression'?

[Chris Belanger via 4D_Tech]

4D continues to NOT QUITE truly and fully support its object notation, and the 
inability to get a pointer to an object attribute continues to confound.

The latest issue involves an attempt to use REDRAW( ) to redraw a subform that 
is named, but whose ‘variable or expression’ as an OBJECT (not a variable).

Because REDRAW( ) does not support a common 4D command structure:  i.e. REDRAW 
( * ; ObjectName ) in addition to REDRAW ( Variable ), then it is impossible to 
use REDRAW on a subform that uses an OBJECT.

Does anyone have a method of getting a subform REDRAW accomplished, when its 
‘variable’ is an OBJECT?

Thanks,
Chris

Re: [ANN] AJ_MATH 1.2

[GI - AJAR via 4D_Tech]

Hi,

Effectively, there was a trace of a method from the AJ_Tools_UnitTest component 
in the AJ_Math component that makes an unwanted dependency.

This is fixed and you can now download the 1.2.2 version which doesn’t have any 
dependencies.

If you want to look at the unit tests, you must launch the "Math-unit-test” 
project. The "AJ_Math.4dbase" is a component and should not be launched by 
itself, but should be put in the “Components” folder inside another project.

Thanks for the feedback.

Re: DOM EXPORT TO FILE adds CRLF

[Keisuke Miyako via 4D_Tech]

the OP is already solved, but on a related topic:

as documented, XML SET OPTIONS only applies to newly created elements.
https://doc.4d.com/4Dv17/4D/17.4/XML-SET-OPTIONS.301-4882274.en.html

so you might ask, what about existing XML documents?

---

until v12, there was a trick to use the deprecated "indentation" parameter 
before export:
https://doc.4d.com/4Dv17/4D/17.4/DOM-SET-XML-DECLARATION.301-4882217.en.html#

today, it's not so easy to "minify" an XML (which is essentially what this 
amounts to, 
since whitespaces between tags are considered formatting and not part of data)

I could not find a way to do it in native 4D, so here goes:
https://github.com/miyako/4d-plugin-xml-minify/releases

---

by the way, if you had a document like

value

the spaces may seem unimportant.

\n
\tvalue\n
\n

would just be a pretty print version of the same thing.

---

but you have a problem once you have something like

some values here

it might have an impact on the semantics 
if arbitrary whitespaces between tags were added, removed or replaced.


some
values
here


this kind of structure is not so common in regular XML,
