Shuttle Item in 3.1

I noticed that since the last update I have problems with the shuttle item receiving an error
Bad Request

This example was set up under version 3.0.1 and every click was collecting the values
shown in the table on the right side. However, since the last update this doesn't work
any more. Is there really a limit of 2000 records per select list?

Hi Carl,
>> … it probably won't happen till next full version, since it does effect js css as well as the HTML source
Yes, I figured as much, and next version will be fine. Thanks.
>> Confusing is bad enough but is there an actual functional difference?
As far as the IDs for the select list goes, If you are aware of the issue, it’s only confusing, but it will work without any changes. With the IMGs it’s a bit more complicated, and can impair functionality. In RTL mode, the ‘Move’ icon is actually pointing from the destination to the source. In the same manner, the ‘Remove’ icon is pointing from source to destination. The user, relaying on the arrow direction, can press the Remove icon, in order to select an option, and will not understand why nothing happen (or, if one of the selected options was highlighted, it will be removed). This can be worst for the user if you didn’t translate the img ‘title’ to a native language. The same effect, of course, is with the ‘Remove’ icon.
You can check the behavior of a regular shuttle item in a RTL page in here - http://htmldb.oracle.com/pls/otn/f?p=22710:260 .
>> just shows that listening to Scott is usually the best course of action
I learned that a long time ago, so no argument here :-)

Shuttle Item problem in Apex 3.1.2

Hi
I created application based on shuttle items in apex earlier version.
The same is not working fine in Apex 3.1.2 version.
I'm not doing any process on shuttle items.
Just created a shuttle item contains a list of values.
whenever i refresh the page,(or say when i press Cancel button to go back to previous page)
shuttle item selects all the values in the list, (i.e values in shuttle items are rolling).
I somehow tried to replicate the same application in demo environment :
http://apex.oracle.com/pls/otn/f?p=12822:4
workspace: vsanthanam
userid: vijay
password: apex_demo
If you see above application, whenever we press button submit. it selects all the values in
Shuttle (actually rolling in my developement instance and not processing further).
Is there anything that we have to take care while using shuttle in newer version?
Thanks
Vijay

Hi Arie
Thanks for your valuable inputs.
While analyzing the issue on two versions: 3.1.2 & 3.0.x ,I noticed few things:
1) Limitation of 2000 values
Had raised SR with Oracle, They have treated this as bug some time back and have temporary resolution as per BUG ID 7326899.
This got temporarily resolved by setting higher value for PlsqlMaxParameters.
As per my understanding: Shuttles never used to refer to this variable value In earlier version. We are on earlier version on one of the instance, where the value for this parameter is still 2000, and despite having more number of values in shuttles on page it never throws error. That shows its a change in new version and behavior is not same.
2) Looping/ Going through all values in left box and then right box of shuttle when page submits.
I am pretty sure at-least about the visual part that it never happened in earlier version what I see on my application on earlier version. But I am not sure about the page rendering / functionality part as this would need regression testing.
So this is second change in shuttle behavior.
Since Business users need all values to be present in the shuttle even after submit for resubmission i.e. again creating the records, so I have not put yet the java script suggested by you to put restriction on length so that it doesn’t loops through values.
I went though the thread where Carl and You have discussed the issue:
Shuttle Item in 3.1
Thanks again Arie!
I am also following with Oracle to get some solution other than following you :-)

Shuttle Item Properties in Apex 3.0

Hi,
Hoping someone can assist with the new Shuttle item in Apex 3.0.
Basically, can someone please let me know how I can perform the following:
a) change the width of the shuttle as when I make a change to the width property, it doesn't seem to make any difference?
b) Am I still able to place headings on each of the shuttle cells like I could when using Carl's example?
c) Based on Carl's original Shuttle implementation, is there any undocumented information relating to the new Shuttle item?
Thanks.
Tony.

Hi Tony,
<p>
a) under Elements>HTML Form Element Attributes, use style="width:200px" to set the width for the item<p>
b) I have not found a way to do that, although others may have<p>
c) Check out the Apex 3.0 documentation for the shuttle item--you basically treat it like a multi-select list, with the source of the item returning a colon-delimited string of values.

How to keep sort order in Shuttle item's source and destination boxes?

I have defined a shuttle item on a page and the list of values in the source box is populated by a SQL with sort order specified. In the Settings of the shuttle item, Show Controls value is set to Moving Only instead of All. When a user moves selected values from the source box to the destination box or vice versa, the list of values does not maintain the original sort order. For example, if I have 26 values A through Z, a user can put value Z before A in the destination box. And when a user move A from the destination box to the source box, A is the last item in the source box. The reset button clears everything in the destination box and resets the source box to the original sorted list. This is not the solution that I am looking for. I would like to see the items in the source and destination boxes to maintain their original sort order all the time.
Is it possible?

How to pass the whole set of values of a shuttle item in AJAX

Hi,
I am trying to pass the value of shuttle item to a dynamic process using Ajax. But if I use shuttle_right, I am able to get only the first selected value. If I simply give shuttle it returns null.
Please let me know How I can get the whole set of values separated by ':'
Thanks,
Vikas

Vikas,
Here's a little snippet that should get you going:
var shtVals = '';
var shuttle = new dhtml_ShuttleObject("PXX_SHUTTLE_LEFT","PXX_SHUTTLE_RIGHT");
for (x=0; x<shuttle.Op1Init.length; x++) {
shtVals += shuttle.Op1Init[x].value + ':'; //Op1 = left & Op2 = right
shtVals = shtVals.replace(/:$/,'');
alert(shtVals);Regards,
Dan

Searching a Table field with multiple values using a shuttle item

Hello All,
I have a shuttle item whhich of course users can select multiple values:
eg: Orange:Pear:Banana
Now I have a table where I want to get the Crate Numbers where these fruit items reside.
The Fruit field has multiple stored values
eg:
Crate Fruits
=== ====
12487 Apple:Orange:Pear:Banana
17653 Orange:Pear:Grapes
12874 Apple:Banana
13655 Grapes:Watermelon:Pineapple
87643 Pear:Banana
53626 Strawberries:Apple
I would like to see a final report similiar to this
Crate Fruit
=== ===
12487 Orange
12487 Pear
12487 Banana
17653 Orange
17653 Pear
12874 Banana
87643 Pear
87643 Banana
I thought maybe this needs to be done using collections but I am not familiar with this function, if their is another way I would appreciate it
Hope u can help
Frank

Hi Frank,
I find that in this sort of case, it is easier to create a link table containing the individual values rather than lumping them into one column.
so the data is stored in the 'Crate, Fruit' format, rather then the 'Crate Fruits' format.
It is a bit more work maintaining the link table when the values are amended and populating the shuttle, but it is a 'proper' relational table then.
Regards
Michael

Set Session State with Shuttle items

Is it possible to have session state set with each item selected in a shuttle? You have a shuttle with 4 possible options, you select item 2 from the left portion of shuttle and it is moved to the right.. Can you set the session state at that point?
What I am trying to do is take the session state after change in the control and use it to populate a text field below. The returned values are used in a sql select to populate the text box with a looked up value...
Thank you,
Tony Miller

Won't this just push the last items value in, as apposed to appending the value?
Tony,
No. Because for shuttle items the return value is stored as colon delimited string.
Means after each change you will have a colon delimited string in the session state with selected values(moved to right).
See this http://apex.oracle.com/pls/apex/f?p=46417:47

Count Selected Shuttle Items

Apex 3.2
I have a shuttle item and a text box.
As the user moves items from the left of the shuttle to the right, I would like to display a count (in the text box) of the number
of items he has chosen.
I know that his will probably have to be done with an onclick javascript function, but I have no idea how to do it.
I cannot use dynamic actions, as this is an Apex 3.2 application.

I was kind of hoping to capture the change event on the shuttle fieldset, but can't, for some reason. I'm too rusty in my js-fu. If that'd even work in 3.2, no clue.
Binding to the controls like Jari suggested works though.
function setShuttleSelectedAmount(pShuttleId, pAmount){
var lAmount = document.getElementById(pShuttleId+"_RIGHT").children.length;
document.getElementById("P5_DESCRIPTION").value = lAmount;
function attachShuttleEvents(pShuttleId){
document.getElementById(pShuttleId+"_RESET").addEventListener("click", function(){
    setShuttleSelectedAmount(pShuttleId);
}, false);
document.getElementById(pShuttleId+"_MOVE").addEventListener("click", function(){
    setShuttleSelectedAmount(pShuttleId);
}, false);
document.getElementById(pShuttleId+"_MOVE_ALL").addEventListener("click", function(){
    setShuttleSelectedAmount(pShuttleId);
}, false);
document.getElementById(pShuttleId+"_REMOVE").addEventListener("click", function(){
    setShuttleSelectedAmount(pShuttleId);
}, false);
document.getElementById(pShuttleId+"_REMOVE_ALL").addEventListener("click", function(){
    setShuttleSelectedAmount(pShuttleId);
}, false);
document.getElementById(pShuttleId+"_LEFT").addEventListener("dblclick", function(){
    setShuttleSelectedAmount(pShuttleId);
}, false);
document.getElementById(pShuttleId+"_RIGHT").addEventListener("dblclick", function(){
    setShuttleSelectedAmount(pShuttleId);
}, false);
attachShuttleEvents("P5_SHUTTLE");
PS: I also want to mention that this may be browser dependant, especially for IE<9 where you would need to use attachEvent instead of addEventListener...
Edit: maybe Paul knows more!

A dynamic select statement as source for a shuttle item: use xmlagg

Here is a suggestion:
If you want to create a dynamic string of values for the source of a shuttle item, you can use the xmlagg trick.
For example:
select rtrim (xmlagg (xmlelement (n, e.ename|| ':') order by e.ename ).extract ('//text()'), ':') employee_name
from emp e
It will return s string of names: ADAMS:ALLEN:BLAKE:CLARK:FORD:JAMES:JONES:KING:MARTIN:MILLER:SCOTT:SMITH:TURNER:WARD
Important is not to forget the "order by" clause inside the xmlagg.
If you have installed the STRAGG function, you could use that one also.
For example:
select replace(stragg(e.ename),',',':') employee_name
from (select ename
from emp
order by ename) e
From Oracle 11gR2 there is another way: the LISTAGG function
For example:
select listagg(e.ename, ':') within group (order by e.ename) employee_name
from emp e

Mathieu

Tags Plugin Incompatible With Shuttle Item

I installed the Learning Library (http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/apex/r41/inst_pkgapp/inst_pkgapp.htm) and found that the Tag plugin is incompatible with the Shuttle Item. Page 17 contains both and the shuttle item does not function. It will not shuttle any items. If I remove disable the Tags item (which is of Tags Plugin type) the shuttle works as expected. I looked around for information on this plugin but did not locate it on http://www.apex-plugin.com/search-plugin-directory. I'd like to keep if but I definitely need the shuttle item working so I may just go with a text item for the Tags field.
Any ideas?
Thanks,
Jason

This error should only appear when you use a list-item with the list-type set to combobox. A combobox in forms is a listitem where you can also enter your own text. If you nly need a dropdown list, set the liststyle to poplist. This works also without patching. if you really need the combobox, patch.

Shuttle Item field width

Is there a way to change the width of the fields in a shuttle item? I have some rather long data items that I'm using in a shuttle. The field width is so narrow that the majority of the data is not displayed. I'm using APEX 4.1

Oddly enough, I actually did search the forum before posting. Apparently I didn't submit the appropriate search terms to yield the answer I needed, but somehow I was able to put the correct terms into the title of the post. I'll have to pay a little closer attention next time. My apologies for transgressing forum etiquette, and thank you for gently pointing it out.

Shuttle Item - changing the arrows

Due o new standards at my company, I've been asked if the shuttle item can be graphically changed. That is, since our Web site has now standards for all types of arrows, I've been asked to change the graphics of the shuttle. How can this be accomplished.
Thank you.

Robert:
You could use JS on the shuttle page that will replace the 'src' attribute on the image tags with values that point to the new image location. Something like // put this in the region footer of the region that has the shuttle
<script>
imgs=document.images;
for (i=0;i<imgs.length;i++) {
// document.write(imgs.src + "<br>");
if(imgs[i].src == 'http://va01:7777/i/htmldb/icons/shuttle_down.png' ) // old image
imgs[i].src = 'http://va01:7777/i/htmldb/icons/shuttle_up.png'; // new image
</script>It may also be possible to set up rewrite rules at the web-server to cause request for the standard shuttle images to get rewritten to a diff location.
