No sure about this but I just re-did part of the database to unify the naming and all of a sudden we start getting a weird error which this link addresses ... http://webomania.wordpress.com/2006/10/01/out-of-range-value-adjusted-for-column-error/

To resolve the problem I simply made the declared data-types in the relevant stored procedures the same as in the database tables. Weird but the problem is fixed.

Frustration Continues

Today I have been pounding away at javascript trying to get a new window to behave appropriately but have instead uncovered some browser differences between Safari and Firefox which may cause me to have to scrap then current approach.

This code works in Safari but does not work in Firefox I finally stepped back to this tutorial from a book after trying for 4 hours to get an Ajax response to appear in the new window to no avail.

childWindow = window.open("","Event Revision");
var doc = childWindow.document;
doc.body.innerHTML="

this is a test

";

This was the approach I wanted to take to deal with Event Revisioning/Commenting & perhaps Relating but it may simply not be possible, which if that is the case will annoy me greatly.

So the last week I was working on several issues and was distracted from core-development.

Firstly I was working on the extended abstract for the WorldComp'08 deadline yesterday.

Also I spent some time working on a small project for OIP.

Today's issue is a leftover issue from last week.

The issue revolves around this

<s:graphicimagedynamic imagerendererclass="#{dataEntry.blobRenderer}"><f:param name="blobIndex" value="#{dataEntry.tempI}"></f:param></s:graphicImageDynamic>I have been having issues getting the correct f:parameter value fed into the blobRenderer class, presently I believe I am boot strapping the parameter from within the bean method that returns the render class object. I am annoyed that I cannot instead use a jsp expression such as,

value="<%=i%>"I have tried several other approaches mixing JSP into the JSF such as a JSP expression which evaluates to a jsf tag with appropriate value but then the tag is simply not rendered. This all frustrates me greatly. The boot strapping method still appears to work but I am not convinced it is the correct solution.

Slow week

2008-02-07T11:28:00.000-08:00

This has not been a productive week. Presently I am going to begin outlining the extended abstract on the paper for the end of the month. At lunch I was meditation on SMS and I am curious about drawing a parallel to HTTP/1.0 in terms of its statelessness. The SMS standard does have features for maintaining state and some other options which are typically not utilized either in carrier network or in the native user interface in the phone. Also I am curious if this is at all Web2.0-ish.

Still at it

2008-02-04T13:42:00.000-08:00

Got the preparedstatement worked out, a silly problem, I was re-initializing the variable after the properties were set.

Added an error message box to deal with invalid input.

Also Ricanek and I looked @ http://www.world-academy-of-science.org/worldcomp08/ws/conferences/icomp08 to submit a paper to.

The general topic is Mobile Computing and the Internet.

The paper will aim to sell the idea of doing mobile computing w/ ubiquitous hardware, a pitch paper. Presently we are ham-strung w/ hardware w/ too many OS's, flavors of OS, no SDK. (Symbian, J2ME, iPhone) so our common interfacing point is SMS. Need to find some other products/projects utilizing SMS. (mobile ed ..?) make a case that there is a marketplace demand for this and it is a untapped resource al la Community Tipping ...

Back to the grind stone

Today I am aiming to resolve my issue with the prepared statements.

Also I realized for input validation I need to go and add several message boxes which provide direct feed back for invalid input.

Also www.communitytips.org is live

Presently I am fighting with PreparedStatements and cannot see the issue. I have code which is identical and varies only accord to which stored procedure is being called. The issue is java thinks I have failed to set the first parameter in the preparedstatement but the code was cut and paste from a working section which I have gone back and re-validated as being functional code. So I am muddling through this. I get the error in both the preparedstatements for providing contact information, one w/ providing a media file, and other w/o a media file . Once I get this issue sorted out the mechanical part of the community page will be functional.

Users will be able to do any combination of the follow:

Provide a tip

Provide a file (a/v or photo)

Provide contact information.

Provide time/date information for the event which they are reporting about

At Dr.Ricanek's request I have made the initial time/date selection boxes be the current actual time.

Also I realized that while the slick Ajax feature for showing/hiding contact information is neat I do actually need to clear out that data if it is initially filled out and then the user decides against providing that information. So I fixed that.

First Posting

First posting hurray,

Presently I have JSF working with the Tomahawk and Trinidad libraries.

Also I have got Ajax functionality working with JSF, particularly the JQuery library.

There was an initial stumbling block with the DOM.

For example JSF transforms,

...

</form&#062

into

...

</form>

Which appears to me to be embedding namespace information in the elements.

The problem here is the ':' appears to kill Ajax's ability to locate that tag.

So if I have an initialization function in Ajax for the webpage,

function init(){

// I want to hide the

tag from above

$("myForm:myElement").hide();

}

The referencing scheme above fails to execute the desired function.

So a first thought is to try and use an escape character, '\'

Giving us,

$("myForm\:myElement").hide();

Which again fails to execute,

After playing around with some over avenues in JSF, particularly the forceId="" attribute which allegedly provides direct access and control to what JSF will populate the id="" attribute with. But I could never get that functionality to work.

So I returned to the escape character method and on a lark tried using two escape characters giving us,

$("myForm\\:myElement").hide();

Which does in fact appear to work.

I am speculating that means that there are two stages of parsing going on and the leading slash protects the second slash so that it is present when the name resolution happens.

Beyond that I have a webservice set up to receive text messages from MobileEd and insert them into the database.

My demo page is

Enough for a first posting. Off to negotiate other issues.
