[trinidad] problem submitting forms in limited mobile browsers
Hi,
I'm facing problems to post forms in Basic XHTML browsers (modern
blackberries and desktop browsers work fine).
I noticed form submission invokes a javascript function, even though
according the docs I should NOT get any javascript:
-----------start snippet-----------------
"...it supports mobile browsers that support Basic XHTML or XHTML Mobile
Profile. WAP 2.0 phone browsers are included in this category. Because of
the hardware performance limitation, Trinidad does not download or use
JavaScript library on such devices.
The following list shows the examples of Basic XHTML mobile browsers.
(snip)
- RIM BlackBerry Browser 4.2 ~ 4.5"
-----------end snippet-----------------
I can see the generated code isn't xhtml, and also I see a lot of javascript
(and particularly to submit the form, using "onclick" event), so I'm
suspecting Trinidad is not detecting properly which browser is accessing.
The User Agent for the mobile is "BlackBerry7100i/4.1.0 Profile/MIDP-2.0
Configuration/CLDC-1.1 VendorID/103"
My questions are:
1) How I can debug which browser is detecting?
2) Is there any way to enforce code generation to basic xhtml?
3) Can I extend and/or add a new 'renderer' profile in Trinidad? (notice my
browser is 4.1, and the doc says at least support 4.2 and above, so maybe is
defaulting wrongly given mine is older...) (as you can imagine after long
tests now I'm facing the "wild guessing" phase :P )
Many Thanks
Francisco

ups...you're right.
The rendering works fine using the latest version in BlackBerry browser
v4.1.0. Tested.
Thanks a lot!

Hi Francisco,
Doesn't seems like a bug. After seeing the code below, I can conclude
that the Survey Demo uses Trinidad 1.x., and is old enough not to have
mobile-related changes. Many mobile features and fixes are available in
Trinidad 1.2.x only. Please try creating a simple page and test it using
Trinidad 1.2.x.

The version described in Trinidad jar's Manifest is 1.2.11.1-SNAPSHOT (I'm
using the version bundled in Jdeveloper 11.1.1.1.0).
I intercepted the html generated for the Survey Demo application (
http://www.irian.at/trinidad-demo/faces/surveydemo/surveyStart.jspx) sending
BlackBerry's User Agent v4.1 and got the html below. Something strange: the
form is invoking a function called "submitForm" on click, but this in not
defined or included in the whole page. Also, notice the code isn't xhtml...
¿What do you think? ¿Could be a bug?
Thanks a lot
Francisco

Re: [trinidad] problem submitting forms in limited mobile browsers

Hi Francisco,
The best way to best detect whether JavaScript is being used or not is
to intercepting your HTTP response using web-debugger like fiddler. You
can download it from the link below:
http://www.fiddler2.com/fiddler2/
In your case, I believe it could have happened that though Trinidad
doesn't use JavaScript, some components might still use some redundant
JavaScript calls - could be a minor bug.
Could you please tell me the version of Trinidad jars you are using?
Also, Please find my answers for your questions inline.
Thanks
Mamallan

#{requestContext.agent.platformName}

No, Trinidad has predefine rules which is not configurable.
