Answer 1

Hello Trent,
I too, am attempting to set the value of an item when another item is changed.
I need to capture the APP_USER changing the row for each row changed in the tabular form when submitted.
My table is in a remote database that is not allowed to have APEX loaded directly in the instance (or db link TO the APEX instance).
Can’t get the APP_USER making the change at this level, as the APEX code is not there.
The instance that hosts the APEX installation accesses the table via a view through a db link.
Can’t use a trigger on the view to set the APP_USER using APEX functionality.
Not desirable to re-invent the IUD wheel using instead-of triggers.
The example you posted on http://apex.oracle.com/pls/apex/f?p=45448:11 is exactly what I need (even though your example sets the value on Lose Focus and I Set value on Change).
I am attempting to implement the dynamic action for the item using your javascript, and am almost there....but not quite. The dynamic action is updating the target item in ALL the rows in the tabular form, not just the one that is being changed.
This, I am sure, is due to my inexperience with Dynamic Actions, jquery syntax, and the javascript API’s for APEX. I believe I know what the issue IS, I’m just not sure how to work around it.
Please note: I attempted to download your example at the above website (turning off popup blockers), but had no success (I got the thank-you for downloading message, but have no clue what was downloaded to where). I was hoping to compare your form Dynamic action with mine to see where I went wrong.
If you could please, review the following and:
1)     let me know what might be different from your working example?
2)     provide info on how to get your working form downloaded (such a tease to have the download link there and not get it to work ;0} ) , please?
The following shows the html from view source for a row in my tabular form. This will help you get an idea of the items. The actual number of rows in the form is about 50.
<table cellpadding="0" border="0" cellspacing="0" summary="" class="report-standard">
<tr class="highlight-row">
<td headers="CHECK$01" class="data">
<label for="f01_0002" class="hideMe508">CHECK$01</label>
<input type="checkbox" name="f01" value="2" class="row-selector" id="f01_0002" />
</td>
<td headers="JOBNO_DISPLAY" class="data">X111Y2222</td>
<td align="center" headers="DEPR" class="data">
<label for="f03_0002" class="hideMe508">DEPR</label>
<input type="checkbox" name="f03_NOSUBMIT" value="1" id="f03_0002_01"
onClick="if (this.checked) {apex.jQuery('#f03_0002').val('1');}
else {apex.jQuery('#f03_0002').val('');}" />
<input type="hidden" name="f03" value="" id="f03_0002" /></span>
</td>
<td headers="UPDUSER" class="data">
<label for="f04_0002" class="hideMe508">UPDUSER</label>
<input type="text" name="f04" size="16" maxlength="2000"
value="MOMSDAT" id="f04_0002" />
</td>
<td headers="DERIVED$01" class="data">MOMSDAT</td>
<td headers="UPDDATE" class="data">13-DEC-11
<label for="f02_0002" class="hideMe508">JOBNO</label>
<input type="hidden" name="f02" value="X111Y2222" id="f02_0002" />
<input type="hidden" id="fcs_0002" name="fcs"
value="DB31F7B9ED99E6A2F7295F6B7D236409">
<input type="hidden" id="frowid_0002" name="frowid"
value="AAATI3AAGAAAAIXAAo" />
<input type="hidden" id="fcud_0002" name="fcud" value="U" />
</td>
</tr>.....
<tr>.....</tr>
</table>
To help explain:
I have a checkbox associated with array name f03_NOSUBMIT,
This checkbox OnClick updates a hidden item associated with array name f03. The hidden item is linked to the depr column of my view/table (this functionality is straight from Oracle’s tabular checkbox wizard – works great, no problems).
When the check box is changed, I need to capture the APP_USER value in the UPDUSER field associated with the f04 array (nice that the array names matched up with your example :0} )
To do so, I created a dynamic action:
Name: Set_Upduser
Sequence: 10 (it’s the only DA)
Event: Change
Select Type: jQuery Selector
jQuery Selector: input[name=”f03_NOSUBMIT”]
--note: the event does not fire if I use f03
--since that value is not actually
--changed until submit with this
--method.
Condition: - No condition –
True Actions:
Sequence: 10
Action: Set Value
Fire When Event Result is: True
Fire On page Load: Unchecked
Stop Execution On Error: Checked
Set Type: JavaScript Expression
JavaScript Expression:
var row = $x_UpTill(this.triggeringElement, 'TR');
var otherElement = $('input[name="f04"]',row)[0];
otherElement.value = '&APP_USER.';
Selection type: jQuery Selector
jQuery Selector: input[name="f04"]
This ALMOST works...
When I run the page and click on just one check box, the UPDUSER fields are updated with the APP_USER for ALL the records, not just the row for the checkbox I clicked. And, if I submit the changes, ALL the records in the table now have the APP_USER in the UPDUSER column. Not just the column where the check box was changed (Which would be expected since all the values are changed in the form – hey, the submit part works :0} ).
Your example at http://apex.oracle.com/pls/apex/f?p=45448:11 works, setting the value for the target field only for that row. If I can get mine to work the same way, I will be good to go (as in hog-heaven, doing the Snoopy Supper-Time dance).
I am thinking my issue is with the row identification in the
--- var otherElement = $('input[name="f04"]',row)[0];
I seem to not be picking up the row value in the row var.
Am I reading line correctly where 'input[name="f04"]' is pNd, and row is pValue? Read the description of the $x_UpTill API, not sure how this is working to identify pValue (Row?).
Additionally, I am not sure what the [0] is for at the end of the otherElement var definition. I don’t see that listed with the $ JavaScript API parameters (Google wasn't much help there either).
OR, am I missing something else?
Once again, if you could:
1) let me know what might be different from your working example? (What does yours have that mine doesn’t)
2) Provide any info on how to get your working form downloaded at http://apex.oracle.com/pls/apex/f?p=45448:11. Please, please?
As always, your assistance is greatly appreciated!
