Hi,

Re: mormot and LiveBindings

I, for one, do not use live bindings.
So I would not be of great help here...
sad

But take a look at mORMotVCL.pas to find out how to create a TSynSQLTableDataSet which will map a TSQLTableJSON for instance.
And generally sample "17 - TClientDataset use".

Re: mormot and LiveBindings

Our TSynSQLTableDataSet is not based on TCLientDataSet, it is a brand new TDataSet inherited class, which get the data directly from the JSON.
Performance is around 7 times faster (in Delphi 7), and memory consumption much lower.
But sounds like if you can't bind our TSynSQLTableDataSet in the IDE, since it is a runtime component, not a design time component...

But I'm not a LiveBindings expert.

Re: mormot and LiveBindings

I immediately decided I wouldn't use it when I saw the first demo of Live Bindings years ago when it first introduced - it uses a way too complex solution for the problem. And I heard performance issue with it.

Re: mormot and LiveBindings

@lele9, just to clarify, it's not my experience but my own judgment based on what I have read and seen.

That's the code I'm talking about - overly complex. Just my two cents.

Re: mormot and LiveBindings

ok, so a question...
if i would like to create my own user interface, how bind the object with component?
now i use a procedure to "bind" objetc and vcl similar at mormotUIEdit with "load" and "save" method but i think there are best method to do...?
anyone have other solution?
Model GUI Mediator pattern is a good solution? it can be implemented at framework level or mormot offer other way to do?
thanks

Re: mormot and LiveBindings

LiveBindings is not very cool IMHO.
Which is why I started this, not perfect either: (Which has moved along a bit since)

But have a look at samples here:

To get LiveBinding sample

Re: mormot and LiveBindings

We have a "UI automatic mapping (via "Mediator" or "MVVM" patterns)" feature request already.
See http://synopse.info/fossil/tktview?name=73c1da3c40

AntonE - if you can (and wish to), you may consider sending us a full sample program, ready to be incuded in the https://github.com/synopse/mORMot/tree/ … PartyDemos dedicated folder.
There is already your CSV2ORM sample in there!

You can join us via webcontact01 at synopse dot info - and send a .zip.
Thanks you all for your submissions!
