Displaying Multiple Values on GUI components - best way to implement

Hi,
my program needs to implement a basic function that most commercial programs use very widely: If the program requires that a GUI component (say a JTextField) needs to display multiple values it either goes <blank> or say something more meaningfull like "multiple values". What is the best way of implementing it?
In particular:
My data is a class called "Student" that among other things has a field for the student name, like: protected String name; and the usual accessor methods (getName, setName) for it.
Assuming that the above data (i.e. Student objects) is stored in a ListModel and the user can select multiple "Students", if a JTextField is required to display the user selection (blank for multiple selections, or the student "name" for a single selection), what is the best (OO) way of implementing it? Is there any design pattern (best practice) for this basic piece of functionality? A crude way is to have the JTextField check and compare all the time the user selections one by one, but I'm sure there must be a more OO/better approach.
Any ideas much appreciated.
Kyri.

Ok, I will focus on building a solution on 12c.
right now I have used a USER_DATASTORE with a procedure to glue all the field together in one document.
This works fine for the search.
I have created a dummy table on which the index is created and also has an extra field which contains the key related to all the tables.
So, I have the following tables:
dummy_search
contracts
contract_ref
person_data
nac_data
and some other tables...
the current design is:
the index is on dummy_search.
When we update contracts table a trigger will update dummy_search.
same configuration for the other tables.
Now we see locking issues when having a lot of updates on these tables as the same time.
What is you advice for this situation?
Thanks,
Edward

Date range to be displayed & Displaying multiple values on the report

Hi,
I have date range parameters, but I also need it to be displayed it on the report. Is there any way I can display it. E.G If a parameter is created one can drag and drop it on the report if it needs to be displayed on the report, I tried to do the same for the date range parameter but it does not work.
Also If a parameter is created by selecting the option 'Allow Multiple Values', and if you drag and drop it on the report only the first value is displayed and the rest does not show. Has anyone tried this before and been successful in displaying multiple values in the report.
Thanks in advance.

Hi,
A multi-value parameter is actually treated as an array in Crystal Reports.
To display the values selected in the parameter, create a formula from the Field Explorer and type this code:
Join({?ParameterName},",");
Place this formula on the header or the footer sections of the report.
Regarding the date range issue, please follow Sastry's advice and it should work fine.
Make sure you're using the parameter in the Minimum and Maximum functions. For eg: If I was to create a date range parameter called OrderDate, my formula to show the start date would look like this:
Minimum({?OrderDate})

Displaying multiple values

Hello,
I have a form with 3 tab pages, in which I am able to display multiple values from the table, but I need to display multiple values for a particular employee. I tried using a loop but it didn't work, and without a loop it only shows one record for an employee.
Thanks,
Nikita

Hello,
I want to make an LOV for a tab page. The LOV will find an employee and display all the skills for that employee in a scroll bar . However my LOV displays only one skill for the employee eventhough the employee has three skills in the database. Is there any way to display all three skills?
Hopefully this makes it more clear.

Interactive Report Displaying Multiple Values (Chart)

Hi guys,
Is there a way to display multiple values into a chart report. Normally there is a combobox and you can only select one value. But i want to display multiple values into one chart and i have to use interactive report because sql report is not enough for me.
Apex product build is 4.0.2.00.07.

Any ideas ?

Display multiple values for a characteristic for Equipment.

Hi is there any way to display multiple values for characteristics of an equipment. Ex. An equipment (Presss) produces multiple ROH Parts. The class VN_TOOl with charactersistic "Part Produced" . When I run IH08 and execute the query, >Show , hide classification I can only get just one part instead of multiple parts. How do I get multiple values for the characteristic

Yes Chandra,
You are not getting it in IH08, but you are getting it in IE07. See this.
IH08
IE07
If you want the report in the ALV layout, then you need to go for a development using FMs in Classification areas such as:
'BAPI_OBJCL_GETCLASSES' 'ALM_ME_CLASS_CHAR_GETDETAIL'

Best way to implement a simple read of multiple stings from a db

Hello guys,
I am trying to read a collection of countries (Strings) into a collection inside a Movie object. The countries reside in a separate DB table with a FK referencing the Movie.
My questions:
1) What is the best way to implement this? Do I need a seperate entity 'country' ? Is there a general way to read many strings into a collection?
2) the countries list does not have to be updated, only read. How do I make sure it is not persistent?
I have noticed that in my JPA implementation (in netbeans) I do not have something like CollectionOfElements (that is present in hybernate).
Thank you,
Marek

Probably yes, you need to have one entity for country.for getting the right answer, Post it here - Enterprise Technologies - Java EE SDK (http://forums.sun.com/forum.jspa?forumID=136)

Event Structures-best way to implement this UI?

I am trying to write a VI to control & read data from 4 different "channels" (each measuring a DUT) at once. I have written all the VI's for initializing instruments, communicating with the devices (VISA, GPIB), setting bias, reading data, etc...that has all completed. I just need to write the overall program with the user interface to allow the user to control these 4 channels & display the measured data.....as it turns out, this is the tricky part! My head is spinning from trying to figure out how to handle all the possible events.
Basically for each channel, I want the user to be able to
-enable/disable it for measurement (e.g. if there is no device loaded in Ch.3, we don't want to measure Ch.3..maybe disable/grey everything)
-set bias conditions (only if channel enabled). Allow user to change bias "in real-time" by increment/decrementing (e.g. incrementing from 5.00 V to 5.01 V, for example).
-turn biasing on/off (again, only if channel is enabled)
Also, I want each channel to display its measured data (e.g current, temperature reading)..every second or so. No graphs or anything fancy (for now! ), just numeric indicator.
Honestly, this all sounds so simple but I'm having trouble figuring out the best way to implement this, due to the fact that 1) there are multiple channels needing to be monitored for events 2) large number of user events that could occur (seems like at least 4 per channel - enabling/disabling, turning bias on/off, incrementing/decrementing bias values, etc ), Also the if a channel IS enabled, i want to be continously reading/displaying the data. What is the best way to handle this? Should i have 4 separate while loops, each with an event structure to handle events for that particular channel..or will that give me grief somewhre?
Also, I have another nagging question. Pretty much all the examples I see re: Event Structures and booleans involve latched booleans, eg. buttons that are just pressed once and pop back up...e.g. buttons you press to tell it to complete a task (e.g. "Acquire Data" or "Stop") , and once it's pressed it's over and reset. In my case, some of the booleans would not be latched...e.g. the "Enable Ch.2" button would be 'TRUE" as long as i want Ch. 2 to be read....does that make sense? Then, say hours later, if i did want to disable that channel, i would change it to "FALSE" and while that would be an "value change", the new value would not be "TRUE"..does that make sense? So not sure if that would be dealt with the same way in an Event Structure.
Hope this all makes sense and many thanks in advance for any help!!!

You're halfway there. I'd say the best solution is a producer/consumer structure, the event structure is used to generate queued commands to the consumer loop.
All data is handled in the consumer loop, where you among other things have an array of clusters of channel/instrument settings. (I usually have several cluster, one for test data, one for instrument settings, one for general settings and so on)
The event structure can have a 1 sec timeout, in which you queue up a Measure command.
In the consumer, in the measure state you loop through your instruments and if enabled you measure them and update their indicators.
The general (smart) way to setup the queue is with a cluster containing 2 elements, a typedef'd Command and a variant.
This way you can send data with the command in any form which is then interpreted in the consumer.
If, e.g. you press the Enable button on a channel, you can enqueue Enable and the channel number.

Best way to implement m to n relation?

Could you please give me some advice on the best way to implement m-n relations in apex?
Example: I want to store server and database info. A server can have multiple database of course. But in case of a RAC database, the database can be running on multiple servers. So I have tables:
create table SERVERS (id number primary key, name varchar2(30));
create table DATABASES(id number primary key, name varchar2(30))
and an m-to-n table
create table SERV_DB(serv_id number references SERVERS(id), db_id number references DATABASES(id), instance_name varchar2(30))
So the table SERV_DB can tell me e.g. that database PROD is running on server 'prdsrv1' with instance PROD1 and on server 'prdsrv2' with instance name PROD2
How would you design an apex page to maintain this information (adding relations, updating instance names, etc)? I have a solution using checkboxes and 2 for-loops over htmldb_application.g_f40 (to process checkboxes) and g_f41 (to process text fields with instance names) and some delete statements but the logic behind it looks too complex for me. I am convinced that this can be done more simpler. Seems like a common problem to me, so I wonder if there is no out-of-the-box solution in apex for this?
Could you please show me or create a small demo application with the solution that looks most elegant to you?
Thanks,
Geert

Thanks for your reply. You modified the question slightly, but conceptually it is still the same. What you call the instances table corresponds with my serv_db table. I understand the solution you propose using the tabular report. If I see it correctly, you would have an insert button above the tabular report for each new relation (instance - server) you would want to add. This is ok for the case i used (databases, servers, instances) because there are relatively few relations. However I would not like this solution for other cases. E.g.:
case: you have a list of persons and a list of tasks. You want to assign tasks to persons in a way that each person has multiple tasks to do and each task can be assigned to multiple persons.
Suppose you add a new person, and you want to assign 15 tasks to him. The solution above (with the tabular report) would be quite some work because you would have to click 15 times on the insert button and on each click select a task from the select list. In this case it would be more appropriate to, after selecting the new person, see a list of all tasks (e.g. 30 tasks) with a checkbox in front, so you can mark 15 out of the 30 checkboxes and press submit. It gets more complex when you want to assign also an attribute to the relation, i.e. showing the list with all tasks, a checkbox in front and a select list next to each task where you can choose from e.g. "priority high" or "priority low" to indicate that this task is high or low priority for that person. Is there an easy way to implement that?

Best way to implement a shared Blocking Queue?

Best way to implement app wide process

I am working on an application that has a list of art work in an sql report.. I want to be able to add each piece to a collection of items (which is stored in a table), so I added another column to the sql report to store the id of the art work. I am just wondering what is the best way to implement the process to insert the item to the collection of items. Since I want to do this from multiple pages - link from art work sql report; link from the edit page for a particular art work; and on the artists page where there is also an sql report, I thought it may be best to have an application process, to save duplicating the process on multiple pages.. however I don't think there's a way to pass the id of the item to the application process? as I was thinking best to have the application process conditional based on request, and then have the link as a doSubmit().
So is it best just to have the link redirect to the same page, passing the id of the item, and then having a process that runs before header that inserts the item, then assigning the item to NULL?
Thanks in advance,
Trent

Best way to implement FREE purchase?

Hi,
I have purchases that are free for logged in users. What's the best way to implement a no-payment solution? Would having the payment fields hidden and COD auto-selected if the amount field is 0.00 a good idea? Is there a better way anyone has implemented this? And how about security flaws?

Hi

What is the best way to implement Carousel i.e. web part in a site page on office 365 site?

We can implement the Carousel web part in many ways like content By Query Web Part , jquery (nivo) plugin or content search web part etc. But among these which one is the best way to implement to get best performance of the page?
Thanks

content search web part always provides best performance because it uses the search. only consideration you need to take is, it does not display the changes immediately and you need to wait for the incremental crawl to happen.

Best way to implement a docking container

Hi everyone,
I need to create a docking container that behaves the same way the draggable panel system works in Flex Builder (Eclipse):
- Dock other containers to the edges
- Automatically layout other containers when the dragged container is docked into/out of an edge
Is there a custom control that would enable me to do this? If not, what's the best approach to create one?
Thanks,
Amir
