WinXP 32, FPC and Lazarus latest SVN checkout.
I was trying to play a little bit with the promising new fcl-web
webdata features to see how JSON/EXTJS works with FPC/Lazarus and came
up with the following problems in the first demo example
...fpcdir...\packages\fcl-web\examples\webdata\demo\
.

I could not yet figure out what the problem is due to limited time at
the moment (2:00AM), any suggestions would be welcomed to find the
solution/fix.
I have fixed the example. Revision 15817.

Hi Michael,
Thanks for the fix. I really look forward to use these new features.
I was testing a little further and here are the current results.
(Sorry if this is a little bit lengthy, but I would really like to see this
through and have super demo programs for both Linux/Windows people.
Also, to learn how to use these new Lazarus/FPC features, of course.)
If I can help with some simple works to get this done - other than these
testings - , please let me know how.
The more it is tested, the better.
If you have ideas for improvement, please let us know.
a; fcl-web, fpweb general
1. It would be really nice to have the fpweb action names generated properly
(like Delphi) in Lazarus ( http://bugs.freepascal.org/view.php?id=15820 )
I think this can be fixed in fpweb by implementing 'GetDisplayName' in the
actions.
2. The other demo apps (demo2...demo6) also have the .rc file line in the
project .lpr source
3. Demos.txt in the ...examples\webdata\ folder mentions Demo1, but the
directories go as Demo, Demo2, Demo3 ...
:/ I'll fix this.
4. The other fpweb dependent demos (ex: fptemplate) were moved into the
\lazarus\components\fpweb\demo\ directory from the fpc\packages\fcl-web.
Shouldn't we have these demo programs in one place only?
Yes and no.
In theory, the demos can work without Lazarus, so it is fitting to put them
in the FCL. But I do use lazarus to develop them, simply because it is much
more easy then.
5. Packages "weblaz" and "lazwebextra" in Lazarus (under fpweb directory)
should have somewhat similar name and definitely some description. In the
Lazarus fpweb directory the file names and package names need to be organized
a little bit. I know this is vague...
I will submit patches with better descriptions.
b; demo (...\examples\webdata\demo)
1. Delete button should maybe have a confirmation dialog and to not have to
click on Save after clicking on Delete to actually delete a record.
I will gladly accept patches for this :-)
2. minor, nice to have: Maybe autosave after leaving any cell after editing?
Bigot Excel/OpenOffice using customers will expect it to work like that. I
know this is just a simple demo...
Same remark as previous. ExtJS has 'autoSave : true' so it should not be
hard.
3. Maybe note for Windows people that they probably need to put the CGI
program into their cgi-bin directory after compilation, and copy the .dbf
file next to it.
? if you use Apache, then an AddHandler .cgi cgi statement should enable
execution of CGI programs anywhere ?
Are you using IIS ?
Then they need to modify the extgrid*.js files and change the extgrid.cgi to
something like "http://127.0.0.1:8080/cgi-bin/extgrid.cgi"; or similar (it
works with .cgi on Windows with Apache, there is no need to have the .exe
extension).
Also, to put the .html and .js files into their DocumentRoot directory under
folder "demo" or something.
Also, to unzip the downloaded extjs zip file into their DocumentRoot (and
there will be an ignorable problem in the docs folder somewhere during
unzipping, because it seems extjs uses menu.html and Menu.html files in the
same directory in one place /v3.2.1/, which Windows does not support).
In short: more installation instructions for the demos ?
4. The JSON html is working now, but the xml one doesn't list anything in the
grid. This might be that I did something wrong, will check demo2 and try both
there.
c; demo2 - demo6
1. "The following package failed to load: lazwebdata" (there are a
lazwebdata.pas and reglazwebdata.pp files in the demo directory, so that
might be something to use somehow)
No, this is the old package name before it was renamed to lazwebextra.
I will check this.
2. minor, nice to have: Would be nicer to use different project names than
extgrid (extgrid.cgi) for people who only use the cgi-bin directory to put
CGI programs on their web server installation and do not overwrite the other
demo project CGI programs.
This could be done, yes. I'll gladly accept patches for this.
Michael.
