Checkboxes with Intermediate Values ("Three State")

Is it possible to create a checkbox in APEX, that has three values? Normally, a checkbox is either checked or unchecked, but you sometimes see them with an intermediate value (sort of looks grayed out), which indicates that the user hasn't chosen a value yet. MSDN refers to this as a three state checkbox...
Thanks.

Hi Chris,
You can definitely disable your checkboxes in Apex, using the attributes parameter of APEX_ITEM.CHECKBOX, e.g.
APEX_ITEM.CHECKBOX( 50, id, 'disabled="true"' )or
APEX_ITEM.CHECKBOX( 50, id, 'disabled="true" checked="true"' )or just
APEX_ITEM.CHECKBOX( 50, id, 'disabled checked' )I don't believe you can have some "third value" on the checkbox, though. It's either checked or it isn't, regardless of whether it's disabled.

Insert checkbox with multiple values

I have created a form I use at work where there are a series of boxes assigned to tasks. I have a tablet pc and have the need to by default, have these boxes blank. Upon selecting the box once, a visible check mark appears. Click a second time in the same box and that check turns to an X. Click a 3rd time and that X returns to a blank box.
To begin, I converted an xfld form (IBM Lotus form) to Adobe PDF in Pro 9. I used the form wizard and almost perfectly it formed in all my boxes. I can make them all check boxes...no problem. Getting them to turn to X's after I click twice.....big problem.
Any thoughts guys/gals?
Gipper

Can you share the form with me so i can see what is happening? You can send it to [email protected] Please include an explanation of the problem in the email. Also can you give me details on the type of tablet you are using and which software and version number is opening the PDF?

Problem with checkbox and "if" & "else if" statement

Hi, i have got something like this:
if (this.rawValue=="0" ){
app.alert("0");
this.resolveNode("Circle1").presence = "hidden";
this.resolveNode("cross").presence = "visible";
else if (this.rawValue=="1"){
app.alert("1");
this.resolveNode("Circle1").presence = "visible";
this.resolveNode("cross").presence = "hidden";
else{
app.alert("2");
this.resolveNode("Circle1").presence = "hidden";
this.resolveNode("cross").presence = "hidden";
I set default position on neutral state. Values are default: on=1, off=0, neutral=2.
When i am clicking on my check box button there works only "on" (1) and "neutral" (2) state. "off" state is not working and i don`t know why.
Please help me with that.

Hi,
Here is the form back to you: https://acrobat.com/#d=qiBnkcpRnPWxA5hokFXvQw.
I have tightened the script, but that was not the main problem. The issue was that the checkbox was on the Master Page and had a default value of neutral. Some objects on the Master Page, like checkboxes with default values and buttons, can misbehave when the form is relaid out (layout:ready event).
If you have a look at the form you will see that the objects on the Design Page behave as expected. However similar objects on the Master Page will revert to default everytime the layout:ready event fires. This has already been logged with Adobe.
I would recommend moving the objects to a Design Page or maybe use a dropdown instead of the checkbox.

Checkbox with 3 states?

Hi,
is there any way in jsf to create checkboxes with more than two states?
Something like
-true (e.g. value 2)
-false (e.g. value 0)
-something in between (e.g. value 1)
You need those when you select a group of features and deselect one of the features (e.g. installation of software, see installshield). The checkbox usually is still selected, but with a shady gray background. You can see if the whole group of features is selected, if the whole group is deselected or if some features of the group are selected.
Is there a way to get those components without having to create them manually? I can't believe nobody else needs those.
Greetings, jimbo

Hi Paul,
It adds the value, how would I (add enter) so the text are seperate lines.
Example 1:
The dog is in the dog house. The cat is in a tree. (bad)
Example 2:
The dog is in the dog house.
The cat is in the tree
Viewing the text as in Example 2 is easier to read.
Thank You,
Arnold

Binding Checkboxes with Data Fields

hi again , one question, is it possible to link a user-added checkbox with a data field from a table to show a stored state?, i tried using the valon and valoff properties to set whether it must or not be checked (depending on the values of some field) but it's not working, could someone help me with this please? thanks

Hi Oscar,
here is my sample, how to connect user's checkbox with DB value.
Dim oCheckBox As SAPbouiCOM.CheckBox
Dim oDBds As SAPbouiCOM.DBDataSource
Set oCheckBox = frm.Items("ckDispp").Specific
Set oDBds = frm.DataSources.DBDataSources.Add("@ABC_DISP")
oCheckBox.DataBind.SetBound True, "@ABC_DISP", "U_Display"
The ValidValues in DB field "U_Display" are 'Y' when checkbox is checked, and 'N' when unchecked.
Hope, this helps.

Three state workflow not complete

Hello,
I'got some trouble with the OOB Three state workflow
It's creating the first task, I change the status to completed and save, it create the second task , I do the same stuff but the workflow doesn't completed..
When I look to the task list I can see that the first task has the % complete to 100% but not the second, if I try to edit the second task to add this 100 I've got the error "This task is currently locked by a running workflow and cannot be edited. "
If I try to set this 100% when I accept the second task , it doesn't complete the workflow...
What Am I doing wrong?
Best regards, Christopher.

Please remember to click "Mark As Answer" if a post solves your problem or
"Vote As Helpful" if it was useful.

The workflow shouldn't be completing if you just duplicate the exact same set of activities for the second task assignment
as you used for the first. Just make sure you use different task tokens, but use the exact approach for task 2 as task 1. The workflow will not complete until both tasks are done.
The approval workflow then assigns a task to each participant in the workflow, who must perform an action on the task. When all the tasks
are complete, the overall task process is complete.Each of these task events must be complete instead of set the percent before
the task process can be complete
please check the process as follows

Compare Old Value (Session State) with New Value on Submit.

Hi all,
Is there an easy way to do comparison of Old Value (Session State Value) with the New Value?
is there an API for that? like what we have in PLSQL Trigger :NEW & :OLD
Thanks before
-Joel

There is only one version of session state available for examination at any point during page rendering or processing, the current version. Can you explain more about what you need?

[OCI] Parameter Binding, repeated Statements with differing values

Hello
I am working on an application written in C which sends about 50 different SQL Statements to an Oracle Database using OCI. These Statements are executed repeatedly with different values.
In order to improve performance I would like to know what possibilities I have.
Whats the benefit of the following "techniques" ?
- Parameter Binding
- Statement Caching
What else could I look into?
with friendly greetings.

It doesn't take zero-time of course, and it does level-off after a while, but array-bind/define or pre-fetching can make a significant impact on performance:
truncated table: 0.907 / 0.918
insert_point_stru_1stmt_1commit: x100,000: 0.141 / 0.144Above I truncate the table to get repeatable numbers; deleting all rows from a previous run leaves a large free list (I guess...), and performance of this little contrived benchmark degrades non-negligeably otherwise. This is a single array-bind insert statement.

select_points_struct: x100,000@1,000: 0.140 / 0.140Above I use array-of-struct defines instead of pre-fetch or array-bind. Performance is just a little better, probably because of better memory "locality" with structures.
The table is simple:
create table point_tab(
id number,
x binary_float,
y binary_float,
z binary_float
So each row is 22 + 4 + 4 + 4 = 34 bytes. There are no constraints or indexes of course to make it as fast as possible (this is 11g on XP win32, server and client on the same machine, single user, IPC protocol, so it doesn't get much better than this, and is not realistic of true client-server multi-user conditions).
There aren't enough data point to confirm or not your prediction that the advantage of array-bind level-off at the packet size threshold, but what you write makes sense to me.
So I went back and tried more sizes. 8K divided by 34 bytes is 240 rows, so I selected 250 rows as the "middle", and bracketed it with 2 upper and lower values which "double" up or down the number of rows:

select_points_struct: x100,000@5,000: 0.125 / 0.122Above 32K, there doesn't seem to be much benefit (at least in this config. My colleague on linux64 is consistently faster in benchmarks, even connecting to the same servers, when we have the same exact machine). So 32K may indeed be a threshold of sort.
In all, I hope I've shown there is value in array-binds (or defines), or even simple pre-fetching (but the latter helps in selects only). I don't think one can very often take advantage of it, and I have no clue how it compares to direct-path calls, but value there is still IMHO. --DD

TFS 2012 - How to Import bulk of historical WI's via EXCEL, with already progressed values in State field within the excel

A user wants to import into TFS, ~ 500 historical bugs that were created and maintained in an excel template outside TFS. While they were maintained outside TFS, the user changed among others, the value of their Status field as well, i.e. there are bugs
in a progressed state e.g. already in status Closed.
Since normally in TFS, one could not directly create a new bug in State = Closed, an error would be yielded when trying to import them as is into regular Team Project. Can u please advise how to easily solve this, without hindering the state diagram of the
model in TFS, and as possible by utilizing GUI of Excel / TFS / other available tool for this purpose ?
Kind thx,

Hi!
You may use excel features for this. Simply copy & paste the state column:
Publish 500 new bugs.
Copy & paste the state column from your source table and publish.
But the reason for state may not be correct. So you may use the more difficult way:
For Source table create the custom state columns (for the cmmi template states Proposed->Active->Resolved->Closed) by this rules:
(Active state column) if (source state == "Active" || source state == "Resolved" || source state == "Closed") { value = Active } else { value = source state }
(Resolved state column) if (source state == "Resolved" || source state == "Closed") { value = Resolved } else { value = source state }
(Closed state column) if (source state == "Closed") { value = Closed } else { value = source state }
Then Publish new bugs.
Copy&paste (Active state column) values and publish.
Copy&paste (Resolved state column) values and publish.
Copy&paste (Closed state column) values and publish.

How to delete a Selected row from datagrid and how to create a datagrid popup with saved values

hi friends,
              I am new to flex.i am doing a flex4 application,i need help for this.
            i am having a data grid with columns.i have two questions.
           Ques 1: when i selected a partiuclar row from a datagrid and click delete button means that record will delete from the datagrid and DTO from the cloud tables also.
            Ques 2: when i save the data grid values using save button means that data will store in respective cloud DTO which is related to the datagrid,
                My requirement is i am using a search button when i click the search button it will show a datagrid that datagrid will contain the previous datagrid datas which is saved in the cloud.
REQUIREMENT example: first screen: i am using with data grid 3 columns (Student Roll number ,Student Name,Student pecentage)---->save--->data will store in cloud DTO.
Second screen: search button ----> it need show datagrid popup.it will have data which we saved in the first screen with same columns(Student Roll number ,Student Name,Student pecentage).
This is my requirement.
Any suggession welcome.
Thanks in advance.

Lets break the problem statement in multiple steps
1. We need a way to know the selection on all rows.
2. We need the association of the checkBox with the data
The solution is to use a arrayCollection/array that holds all the instances created for checkbox.This collection should be a property of component containing the datagrid. We need to use a custom component implementation or inline ItemRenderer. The way you have used is called dropinItemRenderer. Preferaly use custom component implementation and add the instance to the arrayCollection at CreationComplete. Make sure you use addItemAt so that you add the instance in the same row as the data. To get rowIndex the custom Checkbox should implement IDropInListItemRenderer. You could iterate this collection to check all the instances that are checked.
Note: This is the approach considering your dataprovider doesnt have a selection field.

Help with a "AT NEW" statement

I am debugging at some code and I am trying to understand the following statement
<i>LOOP AT it_data_item_final INTO st_data_item_final.
MOVE st_data_item_final-waers TO w_waers.
<b>AT NEW xblnr."xblnr." budat xblnr waers.</b>
      MOVE-CORRESPONDING st_data_item_final TO s_bbkpf.
      s_bbkpf-waers = w_waers.
      t_upload_file = s_bbkpf.
      APPEND t_upload_file.
ENDAT.</i>
I know this code is to only execute when there is a change in the fields but I am not sure how to read the statement. I am assuming there if there is a change in the budat xblnr waers fields of the st_data_item_final table, this code will execute. I am not sure what the xblnr."xblnr." code is trying to do.
thanks for the help in advance

hi,
LOOP AT it_data_item_final INTO st_data_item_final.
v_tabix = sy-tabix.
MOVE st_data_item_final-waers TO w_waers.
AT NEW xblnr.
read table it_data_item_final into st_data_item_final index v_tabix.
MOVE-CORRESPONDING st_data_item_final TO s_bbkpf.
s_bbkpf-waers = w_waers.
t_upload_file = s_bbkpf.
APPEND t_upload_file.
ENDAT.
endloop.
After the at new XBLNR, the structure gets empty and only contains the fields that are left to the field (in the internal table) at which we are performing at end/at new.
XBLNR F1 F2
1     2   4 <-
1     3   6
2     2   4 <-
3     3   3 <-
then it gets triggered at these three positions. To fill the structure again with the values we need to read the table again with sy-tabix.
Hope this helps.

How to checking my checkbox with a listbox

I have a new form where I would like to check automatically my checkbox with a choice from listbox.
I have a listbox with three values in french "Utilisateur" - "Comptable" and "Membre direction".
I would like when the user has selected "Utilisateur", my checkbox with value "OJV_OFFICE_UTILISATEURS" has checked or "Comptable" checkbox with value "OJV_OPF Caissiers"
Can you help me.
Thanks

Look at this previous post:
https://forums.adobe.com/thread/1506686
To modify the script to your form, you could try this as the custom validation script for your combo box:
if (event.value=="Utilisateur") {
this.getField("OJV_OFFICE_UTILISATEURS").value = "Yes";
this.getField("OJV_OPF Caissiers").value = "No";}
else if (event.value=="Comptable") {
this.getField("OJV_OFFICE_UTILISATEURS").value = "No";
this.getField("OJV_OPF Caissiers").value = "Yes";}
Make sure you have the "Commit selected value immediately" option selected.

can anyone help me ...

Also, use code tags and post a SSCCE -- I'm sure more of your posted code is irrelevant to your question and few people are going to look at a code listing that long.

Repopulating a multiselect list with saved values

Hi,
I am new to using HTML DB and have been searching the Internet on information I could find about it.
I found some useful information about multiselect boxes and can get the inserts to work but I am having problems with the repopulating of the multiselect from the underlying table.
I am using the following code to get the information from the table and the process point is On Load - After Header.
DECLARE
l_selected HTMLDB_APPLICATION_GLOBAL.VC_ARR2;
BEGIN
SELECT risk_owner_id BULK COLLECT
INTO l_selected
FROM rmd_risk_risk_owners
WHERE risk_id = :P34_RISK_ID;
:P34_RISK_OWNER_ID := HTMLDB_UTIL.TABLE_TO_STRING( l_selected );
END;
but the multiselect list doesn't seem to repopulate with the values.
Does anyone have an idea I what I could be doing wrong from their previous experience. Any suggestions would be appreciated.
Regards,
Scott.

Lets break the problem statement in multiple steps
1. We need a way to know the selection on all rows.
2. We need the association of the checkBox with the data
The solution is to use a arrayCollection/array that holds all the instances created for checkbox.This collection should be a property of component containing the datagrid. We need to use a custom component implementation or inline ItemRenderer. The way you have used is called dropinItemRenderer. Preferaly use custom component implementation and add the instance to the arrayCollection at CreationComplete. Make sure you use addItemAt so that you add the instance in the same row as the data. To get rowIndex the custom Checkbox should implement IDropInListItemRenderer. You could iterate this collection to check all the instances that are checked.
Note: This is the approach considering your dataprovider doesnt have a selection field.

Mixing multiple checkboxes with grades

I'm looking for a way to mix checkboxes with grades that these checkboxes have scored.
To give an example, say a report has the topics "sustainability" and "durability" and have been scored by clients. I would like to have the option to state that these topics are in the report, as well as how high they scored. This would
enable my to filter for reports that contained the topics "durability" that scored above e.g. "8". Currently I need to create additional fields for every elements, making my database highly unwieldy.
How can I go about creating this kind of database?
Kind Regards,
Nick
Ps: it should be noted that I have limited rights for programming/importing parts. So I'm looking for a out-of-the-box solution.

Hi NLeone,
I don't think you'll be able to achieve what you're looking for in a single column, unfortunately.
You could create a choice column for every potential topic:
Give it a single choice of "N/A"
Display choices using radio buttons
Allowing 'Fill-in' choices
Use column validation to make sure the field value is either "N/A" or a number
