SCAN INDEX broken 18.0 client/server?

[John DeSoi via 4D_Tech]

Just started 18.0 client/server testing and was hoping to deploy sooner rather 
than later. But SCAN INDEX seems to be broken returning zero records in 
client/server mode. 

The other thing I'm not seeing is what I need to do with the users and groups 
directory.json for built client/server applications. It works with 4D Server 
from the default location but not a built server (my default user is missing). 
Does it have to be copied somewhere during the build process?

Anyone care to share their experience with 18.0 deployments? I'm especially 
interested in client/server developed with project (source) mode.

Re: Component methods not properly recognized in parent database

[John DeSoi via 4D_Tech]

What behavior are you expecting? I thought components from the host (even 
interpreted) are read only. 

4D does not do the right thing, but I thought the only thing it should do is 
maybe show the method preview in the explorer. It would be really nice to edit 
the component from the host, but I was not aware that ever worked in any way.

Well Spencer, over 14 years after you posted this suggestion, it saved me!

Automatic overnight upload of my datafile to Amazon S3. Restored it to my 
Backup server and got the error about the database or one of its segments being 
locked.

In Terminal, ran:

sudo chown -R myusername:admin /path/to/my/datafile 

And all was good after that!

Thanks, James.

Code Signing Certificate issues

[Paul Ringsmuth via 4D_Tech]

I have a code signing certificate by the name of "Disability Representative 
Services LLC” and it is visible in the KeyChain Access app on my mac. The 
certificate works on the windows version of my application although it uses a 
different file which I have named something else like RepTools. 

Now I am attempting to code sign my mac version of RepToolsSSD3 with the the 
certificate named "Disability Representative Services LLC” and the build fails 
with the log showing a ton of errors that basically say" Application NO_ERR 0 
Signing tool return status: 0
Application NO_ERR 0 Signed file: error: The specified item could not be found 
in the keychain.

The certificate was purchased and Issued by: Sectigo RSA Code Signing CA.

Does code signing on the Mac require a certificate issued by Apple? 

I’m on v18.0 of 4D on mac Mohave.

Re: Component methods not properly recognized in parent database

[Doug Hall via 4D_Tech]

Well, my component's name is "Foundation_561". (I've changed it a bunch,
but I never changed the name.)

Component methods not properly recognized in parent database

[Doug Hall via 4D_Tech]

While in my main database, when I use a shared method from a component, the
+K shortcut (Goto Definition) directs me to an object method of
one of my parent database's input forms. How do I fix this? I've tried
throwing away structure indexes, with no success. I'm now using v17.3

Thanks!

v18: bug in METHOD SET CODE?

[Jeremy Roussak via 4D_Tech]

I’m using METHOD SET CODE from a component to inject a callback method into the 
host. It’s worked well until now but in v18 it going wrong. The code 
(simplified) is

C_TEXT($hostName;$componentName;$code)
$componentName:="_injectedMethod"
$hostName:="injectedMethod"

METHOD GET CODE($componentName;$code)
METHOD SET CODE($hostName;$code;*)

The method _injectedMethod in the component contains a few lines of comments, 
for testing.

This code creates a method in the host, called injectedMethod, as it should; 
but the method is empty.

If I execute the METHOD SET CODE call a second time, it injects the code of 
_injectedMethod as it should,

Can anyone enlighten me, before I post a bug report?

Jeremy

Write PICT to disk, 64bit

[Bill Hutten via 4D_Tech]

Hi all: We have some 4D Write Pro documents that contain PICT (and other 
format) images. This code will give us a list of all images from the document:

$res := WP Get Elements($area; wk_type_image)

We would like to be able to write these images to disk - but PICTURE TO BLOB 
and WRITE PICTURE FILE both require a relevant codec, which of course for PICT 
does not exist in 64bit 4D. Does anyone have any idea how we might solve this 
problem?


Thanks

- bill

RE: Entity Selection Listbox with Image

[Douglas Cryer via 4D_Tech]

Update.

Having run many tests it would appear that I was experiencing some data issues 
possibly due to some internal data conversion.

Having reset all the thumbnail images in the table the awful lag that was being 
experienced when using an entity selection with a list box went away.  I then 
re-populated those thumbnails that were previously present and all was still 
good.

Classic (current selection) is still ever so slightly quicker on the scroll 
than entity selection but nothing to be worried about IMHO.

Bob Miller said:
I’m very interested in your approach to creating the generic listing.  Have you 
found a demo somewhere that shows how to do this?  I'm just opening the book on 
ORDA and this is one of the first projects I'd like to try, but am befuddled 
where to start.

What are the features of your generic listing?  What does it look like?  Can 
you share a bit about your spec and how you are going about creating this?

It is a bit too much for this list but maybe we could touch base offline.  4D 
showed a demo at the World Tour and I am sure someone else will be doing 
something at the Summit.  In short our approach is as follows:

We are writing as a component as it will eventually replace the existing 
"classic" Browser component that we have been using for many years.  We are 
using the project methodology as this works really well for writing components.
The interface is largely driven by a single window made up of:
- Side bar to list the tables
- Data list area which is populated based on what is selected from the sidebar
- Header/button area that is populated by buttons many of which have standard 
options mixed with actions governed by the host via callbacks

The component will require the host to have a single table to hold objects for 
the various tool elements such as:
- Saved searches to be used by the components search editor
- Saved views to allow the user to have multiple view definitions
- Saved selections to allow the user to save selections and manipulate them 
like sets via Venn diagrams
- Saved sorts to allow the user to apply a predefined sort to selection

So far we have been working on it in our spare time for less than a month so it 
is very early days.  We have a working model and are building out the 
functionality when we have a spare moment from our heavy workload.
