I misunderstood that point, it's interesting, how do you handle that ?
How do you use XHTML inside LZX for data transfer ?
Are you using <HTML> tag ? If yes, what do you put inside for data
transfer ?

... to be (more) precise: I switch from LZX to XHTML just when it comes to
data transfer from applications (comprising embedded LZX) to data sources.
In many other cases I extensively use LZX; it's great pleasure (as you may
have seen from my website www.eines-alles-nicht.org or from the following
small application for my grandchild:
http://www.eines-alles-nichts.org/Niels/Spiel.html).

OK, but I really need LZX, XHTML is not equivalent and I need the power of
LZX for the end user experience.

Hi Jean-Baptiste
Sorry, I didn't realize that in your codeline:
ds.setAttribute("src", "test/nimportequoi"); 'nimportequoi' stands
for the URL of some Java servlet.
When trying something similar using php on the server-side (along the
lines of chapter 35) I failed - and meanwhile switched from LZX to XHTML.

Hi Jean-Baptiste
According to my knowledge of OpenLaszlo socalled data-binding via the
'src'
attribute of 'dataset' is in fact not data-binding but just
data-bound data-retrieval. It's a one-way functionality. Isn't it?
Binding via src ? What do you mean ?
I'm using xpath on widget with datapath attribute, not src at all...
And again according to my understanding of Laszlo things to
udate/delete/insert data to the 'src' you have to call some server
side program (php, jsp, asp, etc) that can handle data sources (e.g.
a XML-file, a relational DB).
That's exactly what I'm doing : servlet = java server side.
Did you read chapter 35: Building Data-Driven Applications in the
software egnineer's guide?
Yes.

Subject: [Laszlo-user] Sending dataset over HTTP
Hi the list !
I would like to send over HTTP the content of a dataset. Nothing
complex ins't it ?
But I got problems ... Let me explain :
<dataset name="PetCreate1_pet_embeded_ds">
<pet
animal="aaa"
entryDate="aaa"
dateBirth="aaa"
age="aaa"
name="aaa"
sex="aaa"
streetNumber="aaa"
streetName="aaa"
code="aaa"
town="aaa"
</pet>
</dataset>
That dataset if mapped via xpath to different text field. (that
dataset do not come from HTTP but is hardcoded like that in the lzx.
Here is the code I use to send the dataset :
<handler name="onclick">
var ds = PetCreate1_pet_embeded_ds;
Debug.write("Seding data ...");
ds.setAttribute("querytype", "POST");
ds.setAttribute("type", "http");
ds.setAttribute("request", "false");
ds.setAttribute("src", "test/nimportequoi");
//var param = new LzParam();
//var xml = ds.getPointer().serialize();
//Debug.write(xml);
//param.addValue("xml", xml, true);
//ds.setQueryString(param);
ds.doRequest();
</handler>
As you can see I try different thing to pass the XML.
I have to explicitly add xml string as a param if I want to catch it
on the Servlet.
In other words, with that commented version, no XML on the servlet !
Why ?
In other part of my program I got on the servlet the following error :
2007-10-19 12:21:06.076::WARN: /petshop/:
java.net.MalformedURLException: no protocol: <localdata/>
or depending on some line commented or not, 2
2007-10-19 12:21:06.076::WARN: /petshop/:
java.net.MalformedURLException: no protocol: <here all the dataset
XML>
So I got the XML but with that error everytime.
Any clues ?
thanks !
