ApEx2: Many-to-many with checkboxes or multiple select list?

Hello all together
I have the following specification:
* a table for tool users: tool_users(tu_id, tu_name)
* a table for groups: groups(gr_id, gr_name)
* a table for the many to many relationship of tool users and groups: tool_users_to_groups(tu2gr_id, tu2gr_tu_id, tu2gr_gr_id)
I'd like to have some checkboxes or a multiple select list in my "add/edit group" form where I can select which users belong to this group. The same vice versa for users to specify which groups they belong to.
edit user
(general details)
Has to the following groups:
[X] Group 1
[ ] Group 2
[ ] Group 3
[X] Group 4
[ ] Group 5
After submitting the checked values should be insert into the many-to-many relationship table.
How can I do that?
Thanks a lot for any help,
Josh

Thanks for your kind help.
I'll have to learn PL/SQL if I want to go on with my work in ApEx in future, I see this too.
But at the moment there are just a few problems I got and I should get a small application up and running as soon as possible, so I'd be really thankful for some newbie help.
My problem is now:
I have created the process for my form page with the following code:
declare
v_list varchar2(200);
begin
for r in (select tu2gr_gr_id id
from tool_users_to_groups
where tu2gr_tu_id = :P3_TU_ID)
loop
v_list := v_list ||r.id|| ':';
end loop;
:P3_GROUPS := v_list;
end;
Sadly the code does not seem to be executed. I have changed the name from :P3_GROUPS to :P3_GROUPS2 (which doesn't exist and I'd expect the application to crash when loading the page). I have set the process to a Before Header process. What could I have done wrong?

Select MULTIPLE default values for a multiple selection list box based on another field in Infopath 2010

Hello there - Before I explain my issue, I would like to point out that I have reviewed some other discussions on selecting default values for multiple selection listbox. But my issue is specific and different, and not answered by any of the discussions
I visited.
I have a multiple selection list box (say for example all countries in the world as values), and I would like to pre-select or setup multiple default values (say five countries) based on some criteria that I query from MS SQL database table.
I know we can go to Data | Default Values option to setup one or many default values for multiple selection list box. When I enter the default values manually this works. I also right click the field under the Multiple-Selection List Box group, then select
Add another Value Below and set the Default Value for this field to setup multiple default values.
However, if I reference a field (either an infopath field or a field from SQL database) I am not able to setup multiple default values. Infopath automatically selects the last field I selected for all instances and in the end I am able to see only one
default value selected instead of many. How to fix this problem? Why would infopath allow multiple default values when we enter it manually but not when we reference some fields?
Please let me know if you need more info. Appreciate your help.
Thanks!

Hi redhotc,
According to your description, my understanding is that you want to set multiple default values for a multiple checkbox list in InfoPath form.
I did a test with SQL database table. I set three default values for the checkbox list by adding three values field under the group field(Data->Default values), each value field is for a default value. Then publish it to my SharePoint site, everything
was fine.Please have a try as the below link:
http://www.bizsupportonline.net/infopath2010/pre-select-items-multiple-selection-list-box-infopath-2010.htm
Note: if you are using SQL databse table, you may need to enable ‘Allow cross-domain data access for user form templates that use connection settings in a data connection file’ in CA. More information, please refer to:

Multiple-Selection List Box Values in Multiple Columns

I am using InfoPath 2010 with SharePoint 2013. I have a form with a multiple-selection list box which has A LOT of choices. Instead of displaying all the choices in one column, is it possible to display the values of my list box in several
columns?

Hi Andrea,
I agree with Brij, one multiple-selection list box is associated with one list field, we cannot use the one multiple selection list box value for other multiple selection list boxes, we need to create multiple choices for each multiple-selection list box
control in InfoPath form.

How can I have multiple-selection list box "select at least one checkbox" option active only when the section it's in is visible?

Hi, I'm using SP13 and InfoPath2013.
I created a custom form and published it to SP13 document library. This form has many MSLB. Depending on the checkboxes selected in the 1st MSLB, the other MSLB will either hide or show. Each MSLB is in its own section. The requirement
is to have each MSLB to have at least one checkbox selected. Well, the problem is that when that MSLB isnot checked in the 1st MSLB it is not visible and shouldn't require any checkbox to be selected. However, the form can't get submitted instead
an error dialog would pop up and ask user to make a selection for MSLB that is not even displayed. Is there any way to fix this besides unchecking all MSLB to be not required at least one selection? Thank you.

Eric,
I follow your reply post here and still doesn't work. I also noticed your screen shot of selecting a field is not the same as what I see in InfoPath 2013.
Here is what I did,
1.Check At least one selection required for
these Multiple-selection List Boxes
as you want .
2.Create a Formatting rule for the 2nd
Multiple-selection List Box.
3.Add a Condition as below:
4. I get a validation error if I don't
select at least one checkbox in the hidden MSLB control when submitting.
I think I'm following all the steps correctly
but please let me know if I'm not.

Choices - Checkboxes (allow multiple selections) Links

Is there a way to make the below possible:
This is with respect to Sharepoint 2010 list functionality
I have a list with 7 choices
The type of choices is: Checkboxes (allow multiple selections)
Is it possible to have links as the various choices as compared to plain text?
Is there any other alternative to have links with multiple selection option which works like choices option in a list?
Thanks,
Abhilasha Thackur

Hi,
According to your post, my understanding is that you wanted to have links as the various choices as compared to plain text.
There is no out of the box way to accomplish this with SharePoint.
By design in SharePoint, the options in the Choice filed look like Single line of text type.
To achieve what you want, you need to custom filed Type programmatically.

Multiple Select List does not Refresh with Dynamic Action

All,
Scenario:
Using APEX 4.2.2, I have a Select List page item (P4_SPONSOR) set to allow multiple values which has a dynamic LOV to populate the list. What I would like to do is highlight the display values based on another page item's value (P4_DRIVER_ID). When I set the source of P4_SPONSOR to static text, such as a delimited string of 1:2:3:4, any display values where the return values are equal to the static text are highlighted when the page loads.
Problem:
The problem lies in trying to use a query as a source for P4_SPONSOR which is filtered based on the other page item, P4_DRIVER_ID. For instance, my SQL Query (returning colon separated values) returns the same as the static text noted above. In the query's WHERE clause, I specify that the driver's ID is equal to P4_DRIVER_ID:
SELECT sponsor_id
FROM sponsors_drivers_xref
WHERE driver_id = :P4_DRIVER_ID;
This, as I understand it, would necessitate a refresh of P4_SPONSOR whenever the value of P4_DRIVER_ID changes. So, I have a Dynamic Action that does just that. When executed on the page, I can see the P4_SPONSOR multiple select list actually refresh, but none of the display values become highlighted.
Thoughts?
Thanks,
-Seth.

Seth,
A dynamic action refresh of your select list will refresh the list of values (this is what you are seeing), it will not refresh the value of the item itself. In fact, it will remove any values that you had already selected. To refresh the value you will need to add additional dynamic actions.
Create another dynamic action with:
Event: After Refresh
Selection Type: Item(s)
Item(s): P4_SPONSOR
If this was a normal select list you could just create a Set Value action and use your query to set the value of the select list. Since this is a multiple select list your will need to get your colon delimited value first and then use some javascript to set the values of your select list.
Create an hidden page item name P4_SPONSOR_TEMP.
Add a true action to your new dynamic action:
Action: Set Value
Set Type: SQL Statement
SQL Statement:
SELECT sponsor_id
FROM sponsors_drivers_xref
WHERE driver_id = :P4_DRIVER_ID;
Page Items to Submit: P4_DRIVER_ID
Selection Type: Item(s)
Item(s): P4_SPONSOR_TEMP
Add another true action to your new dynamic action:
Action: Set Value
Set Type: JavaScript Expression
JavaScript Expression:
$("#P4_SPONSOR_TEMP").val().split(":")
Selection Type: Item(s)
Item(s): P4_SPONSOR

How to submit a multiple-selection list box in an Infopath Sharepoint form as multiple entries on a Sharepoint list?

I would like to be able to submit an Infopath form with a multiple selection list box in Sharepoint as multiple entries on a Sharepoint list.
For example, a user has to complete the following fields:
First Name:
Last Name:
Favorite Color (can select more than one):
[] Blue
[] Red
[] Yellow
[] Green
If the user picks blue AND red and submits the form, the Sharepoint list would feature TWO entries, both with their first and last names, but with different colors in the "Favorite Color" column.
Please let me know if there is a way to do this. Any guidance would be helpful!

Set focus on item that selected in multiple-selection list box field in infopath

Hi
I have multiple-selection list box field in infopath that have for example 40 items. (I customize sharepoint list with infopath),then
publish infopath form in to sharepoint list. users want to add new item,when they selected or checked each item in multiple selection list box, after that automatically control focus on first item, but I want to focus remain on that item
I was selected. Why this happen?! I also set postback settings to “never” in multiple-selection list box properties. But didn’t work.
Thanks.

Hi,
According to your post, my understanding is that you wanted to find several columns based on user selection of checkboxes in one of the Multiple-selection List Box.
I recommend to customize the form to concatenate values from choice field (with multiple values) into single line text box, and then hide the fields based on the text box value.
We can follow the steps as following:
Add a text box control(filed 3) on the form to hold the value selection in the multiple selection list box.
Set the default value for the text box control as
substring-after(eval(eval(Value, 'concat(., ";")'), ".."), ";")
(you need to change the ‘Value’ in the formula to your multiple selection list box name: filed1).
Add the conditional formatting on the flied: flied 3 does not contain value (you need to change the ‘Value’ in the formula to your multiple selection list box value.).
In addition, you can add Formatting action to hide the text box control.
Here are the result screenshots for you to take a look at:

Short answer, use the apex_util.string_to_table to convert to a table; then you can either iterate through the table to generate a string of names, or accomplish the same with a bulk operation.

Multiple Select List looping thru PL/SQL function body returning SQL query

Hi,
I have a Multiple Select List. I want to loop through the values from the Select List and process them in a PL/SQL function body returning a SQL query. Currently, my code only returns the SQL SELECT results of one item in the select list. How do I change my code to make it return the results of all of the items in the select list? (I tested it and it is definitely picking up all the values in the select list).

Thank you,

Laura,
First, I would be careful of introducing SQL Injection possibilities. Any time I see
'Select ... ' || :P123_FOO || ' ... '
I worry about sql injection. In your case you are converting :P50_SELECTED_INSTRUMENTS into selected_items and then selected_items into s. So when I see
'WHERE TO_CHAR(orig_geo_loc_sys) LIKE ''' || s ||'%'' '||
I think, "I could use sql Injection and hack this."
So, I would do some validation on :P50_SELECTED_INSTRUMENTS or some other method to avoid this.
I'm not certain I understand your query. Do you really intend to allow the user to select the beginning of a string and then find all rows that start with that string? Or, do you just want to let them find when it matches the string. This is one way if you want to do matching:
DECLARE
selected_items HTMLDB_APPLICATION_GLOBAL.VC_ARR2;
s VARCHAR2(32767);
q varchar2(32767);
BEGIN
-- Change the : separate string to be comma separated with quoted strings
s := '''' || replace(:P50_SELECTED_INSTRUMENTS, ',', ''',''')|| '''' ;
-- htp.p('COUNT: '||selected_items.count);
q:= 'SELECT '||
'SUBSTR(orig_geo_loc_sys,1,INSTR(orig_geo_loc_sys,''-'')-1) AS INSTRUMENT, '||
'SUBSTR(orig_geo_loc_sys,INSTR(orig_geo_loc_sys,''-'')+1, LENGTH'||
' (orig_geo_loc_sys)) AS ORIG_LINENUM, '||
'sum(orig_intrl) orig_intrl, '||
'sum(orig_extrl) orig_extrl, '||
'sum(recv_intrl) recv_intrl, '||
'sum(recv_extrl) recv_extrl '||
'FROM line_usage_sum_view '||
'WHERE TO_CHAR(orig_geo_loc_sys) in (' || s ||' ) '||
--'WHERE TO_CHAR(orig_geo_loc_sys) LIKE ''2213003%'' '||

'AND call_start_date > TO_DATE(''30-NOV-1999'') ' ||

'TO_DATE(:STARTDATE,''dd-MON-YYYY HH24:MI'') AND '||
'TO_DATE(:STOPDATE, ''dd-MON-YYYY HH24:MI'') '||
'GROUP BY GROUPING SETS (orig_geo_loc_sys)';
-- htp.p('SQL query: '||q);
RETURN q;
END;
If you want to do something more like you originally stated, try this:
DECLARE
selected_items HTMLDB_APPLICATION_GLOBAL.VC_ARR2;
s VARCHAR2(20);
q varchar2(32767);

Setting current values in Multiple Select List in SQL Query based Report

Hi,
I have a report based on a sql query that contains a multiple select list. Unfortunately I cannot get the multiple select list to display the current values (p_value) correctly. I have created a page item, :p311_current_versions, that is set using a pre-header process and it returns a value with a colon delimited format e.g. '10.1.2.1.0:10.1.2.2.0'. Then this item is used in the sql query to set the current value (p_value) of the apex_item.select_list_from_query function. However when the table is displayed, instead of having two entries, 10.1.2.1.0 and 10.1.2.2.0 selected, it has an extra entry '10.1.2.1.0:10.1.2.2.0' selected.
Here is my code:
select distinct a.product, a.version from (
select distinct
apex_item.display_and_save(2,product)||apex_item.hidden(1,env_product_id) PRODUCT,
APEX_ITEM.SELECT_LIST_FROM_QUERY(3,decode(product, 'HTTP Server' , :p311_current_versions, version), 'SELECT distinct version d, version r FROM ebs_tech_stack where
product ='''||PRODUCT||'''',
decode(PRODUCT, 'HTTP Server' ,'multiple="multiple" style="width:170px"','style="width:170px"'),
'NO') as version
from ebs_environment_tech_stack
where environment_id = :p311_umgebung_id) a order by a.product
If anyone can help me figure out how to set the current values correctly I'd be really grateful!!
Thanks in advance,
Jean

Jean,
I don't think this is possible using the apex_item package. The select_list_from_query function accepts only a single value for the second parameter.

Using multiple select lists in ADF

Hi,
I am trying to use a multiple select list in my JSP page, and have a method in the ApplicationModule be called when the Struts action is called. I am following the example ADF tutorials, where the method is added to the ApplicationModule class, then dragged onto the Stuts Flow diagram (to associate it with an action).
I am able to create a dyna form bean for the page that contains the multi select as a type "java.lang.String[]" (string array). I am able get that values that were selected in a normal action's "execute" method. For example:
msf = (DynaActionForm) form;
String[] statusSelection = (String[]) msf.get("multSelectList");
However, I cannot seem to get the "multSelectList" values into a method in my Application Module class. The "multSelectList" is defined in my dynaFormBean as a String[] type. I am passing it in as an argument like the following....
public void setParams(String multSelectList[]) {
This results in the method not being called at all. I am not sure why. Does this have something to do with a String[] not being serializable??
However, if I just attempt to pass other types form items to the method, it works. For example:
public void setParams(String simpleCheckbox) {
Does anyone know how to use multiple select lists in conjunction with ADF?
P.S.
my multSelectList looks something like this:
<select name="multSelectList" multiple size="5">
<option value="ALL">Select All</option>
<option value="preferred">Preferred</option>
<option value="standard">Standard</option>
<option value="approved">Approved</option>
<option value="interim">Interim</option>
</select>

I got this working by changing the signature of the Application Module method to use ArrayList rather than String[], then you can marshal the Struts FormBean contents into an ArrayList to pass up.
To do this, subclass the DataAction by using "Go To Code" off of the context menu and then override the initializeMethodParameters() method:
protected void initializeMethodParameters(DataActionContext actionContext, JUCtrlActionBinding actionBinding)
    //Get the String Array from the Form Bean
    String[] selection = (String[])((DynaActionForm)actionContext.getActionForm()).get("multiSelect");
    //convert that to an ArrayList
    ArrayList selectionArr = new ArrayList( Arrays.asList(selection));
    //Add that object to the Arg List for the AM method
    ArrayList params = new ArrayList();
    params.add(selectionArr);
    actionBinding.setParams(params);
}

Multiple selection lists in abap report

I need to populate a multiple selection list and then read the selection in an ABAP report. A parameter with list box is not solving my purpose.
Please give any suggestion on this.

Hi
If you can't use the SELECT-OPTION statament, there's no standard solution.
U can only try to create a table control with only one colunm and every hit of the table control is a single hit for the selection.
To insert a table control in a selection-screen u need to use the statament:
SELECTION-SCREEN BEGIN OF TABBED (see the help)
In order to create a TAB where u can load a subscreen where u can insert a table control.
The u need to transfer the hit from table control to a range.

Multiple selection list and passing that value to oracle reports

Hi
I need to create a multiple selection list and then based on use selection, I need to pass that value to oracle reports. Can any one help with steps on how I can do this. Thanks

Hi
Concatenate the multiple values into a string separated by comma and then pass that string to report as a parameter.
In report query, you have to use the lexical parameter using ' & '
