How to build a dynamic array index in the attribute 'to' house arrest
Hi allI need to generate xml output with the appearance of multiples of the same complex element. The number of items is calculated dynamically. I use bpelx: append to add items, but I'm crashes when I try to assign values to elements using a variable to index items.
How can you dynamically assign an array index variable in the attribute 'to' a copy instruction? I was able to do in the attribute 'from' the copy statement, following the examples indicated in the documentation for the xpath function. But when I use the concept of intermediate variable, I get a compiler error stating that the query attribute must start with ' / '.
It works fine when I hard code the index in the attribute of "query" in the statement "copy to".
I use 10.3.3 version JDev and 10.3.3.0 PM BPEL version.
Here are the two methods I've tried:
----------------------
< copy >
< expression = "concat ('/ client: assTestProcessResponse / client: ScreeningComments / client: CommentItem [', bpws:getVariableData('notesCount'),'] / client: CommentText')" / >
< variable = "queryText" / >
< / copy >
< copy >
< expression = "bpws:getVariableData('noteText')" / >
< variable = part of the 'outputVariable"="payload ".
Query = "bpws:getVariableData('queryText')" / >
< / copy >
----------------------
< copy >
< expression = "bpws:getVariableData('noteText')" / >
< variable = part of the 'outputVariable"="payload ".
Query = "/ client: assTestProcessResponse / client: ScreeningComments / client: CommentItem ["bpws:getVariableData("notesCount") " ""] / client: CommentText "/ >
< / copy >
----------------------
Has anyone had a similar problem? Please let me know this is doable and how.
Thank you

Hello
I don't know if the following solution is what you want, but I'll try to explain how this would work; (o)
I understand your question, you have a following like the watch of simple structure xml schema:
The
As you explained that you know how to add loose, common is to use an XML Fragment example As you can see now there are two elements
After the task to assign the variable content looks like: After adding the fragment, you can set the value for the for the first content element in the following way: The important thing is to know how to point to the correct position within the payload. It works with that part of the query statement or you can of course use the short version The next task is to dynamically create the reference to the position. Therefore, you can for example use a variable. You can for example something like this: And the last step is to set the element of content dynamically using the defined variable The only thing to use the defined variable is that part of the query: Finally, the XML Structure should look like this: Concerning Alex

[position()=bpws:getVariableData('Position_Variable')]

How to fill a dynamic array according to the choice of the Viewer
Hello
I came across a dead end on my page "events".
There is a dynamic array, get the information from a database. Initially, it will display upcoming events.
At this point, my question is this:
* Can fill the dynamic table based on a condition where the current date and the date of the event (as in the comic book) will be compared and if the date of the event is aware of the date, it will appear in the table. Otherwise, it will not.
If I can do it, can someone please help me with the code?
In addition, on the right side of the page there are 3 options for the Viewer:
1. display upcoming events
2 discovered past events
3 search for events by month and year
What I want to do, is that when the viewer clicks on 'past events', the table will be reset and populated by these events, whose date is exceeded.
When the viewer clicks on "upcoming events", the table is reset again and filled with the relevant events.
When the viewer selects a month and a year, the database to find reviews of research.
Can we write this in php? Since I read smwhere that php does not work with onclick functions... I got confused. Cuz in my table data should vary depending on what the Viewer is clicking (coming events/events/research past events). I do not want to create pages for each type of event.
If anyone has a better suggestion to complete this task, please share!
Thank you!

Of course. Just compare the date field in your database with the current time as returned by the function of date of your DBMS. Assuming you are using MySQL, you would compare your column with the currdate() function and the appropriate use of upper / lower to operators in the WHERE clause. If you don't know what a WHERE clause is then I invite you to learn SQL as soon as possible. You can't build data sites without a basic knowledge of SQL.
> Since I read smwhere that php does not work with onclick functions...
This means that php is a server side, where interactions with the user always occur on the client's site. But that doesn't mean that you can't call action from the side event on the client side server. Certainly, you can and would be.
You should consider adding links to the page of dynamic array passing a querystring to the php script that determine which filter to add in the future WHERE clause to the current date, less, etc..
Also, in the future, please post those questions on the application development forum.

Building a dynamic array or the live 3D route
I am trying to build a dynamic graphic 3D system with information flowing through a serial port. For example, to draw something like a topographical map living with live GPS coordinates and elevation digital. The longitude and latitude are the graph XY and elevation will be Z. currently, settings have been isolated in 3 distinct values of DBL. They are then indexed in 3 different and introduced tables in a 3D VI field. I put the process while a while loop is encompassing the process of isolation and a tunnel of automatic indexation to the exit from the while loop. The problem with this configuration is that the indexed table is only sent at the end of the while loop, so end the process, preventing a direct path data. Is there anyway I can get around that?
Thank you!
Use a shift register to store the data and update all data (using the table of construction) to the INSIDE of the loop. (Note: not the table grow without limits since it will eventually kill performance).
I did something very similar to show air speed vectors in space 3.

How to fill a dynamic array in the form of Adobe Livecycle with cfpdfform?
Hi all
After two days of searching about it without results, I hope someone here can help me.
The problem:
I have an Adobe PDF form created with Adobe Livecycle Designer that has a dynamic table inside. The Table1 table consists of a header line with 4-cell text and a data line Row1 with four cells each with a Textfield Cell1 and Cell2, Cell4 Cell3.
Table 1 is inside a subform mytable. The subform is made to flow and the Row1 the link line repeat for each item of verified data.
Everything is included in the form1 form standard subform.
When I use the following code, I assumed that the table should have two rows... because it says it will be dynamic:

Please can someone enlighten me?

When filling out your fields of pdf, you can search through all the records in a query as follows...
He will manage two lines or thirty anyway. In this case my fields in the pdf file have the line # as a suffix.

What is the purpose of the function Array Index in the example attached?
Hello
I'm fighting with the Array Index function. I found the attached VI on the OR site which was exactly what I wanted to do, but rather than simply accept that it works and use it, I wanted to understand.
What is the purpose of the function Index of table inside the while loop? If I put a probe on part and on the other, the values are the same, but if I remove the service and connect directly to the > function, I get an error.
I do not understand the tables but I don't understand what is happening here. Any help would be appreciated gratefully.
Thanks in advance.
It is just picking the first reading of the table in the waveform. If it's good enough (I'd take at least the average of N samples), why not cela?

As in the screenshot above, I have data from 2 sources to a "generation table" function, thanks to a function "convert to dynamic data", an entry on a file of measures. I want the data to be saved as 2 columns, one for X and one for Y. What happens instead, it's that it gives me a file with only 1 column and entered data alternated, i.e. {x 1, y1, x 2, y2, x 3, y3... etc.}
The Web site of NOR and the context help to make believe that the array of build service must be able to do this if "Concatenate entries" is not selected (which it is not, in fact it is grayed out and I can't select if I wanted to) but I am a little confused.
If you double-click the .vi "Convert to DDT" (the little thing on the data immediately before writing to file .vi line, you can change what type of data is to enter the 'write'.vi. Make sure that it is set to 1 D array of scalars, several channels of.

Hallo!
I tried to put entries generated in a table with the current value of the time stamp in the first column and the data of a table 1 d of waveforms of 4 cards in the other 4 columns.
I have some difficulties to match the data in the table. I ve simulated the code I've written and I see that the time stamp but I ve got none of the values of data in my table. I want to ask you what you think of my code and how can I achieve my goal?

How can I detect dynamically new modules of the cFP-2200?
Hello
I'm working on a project that monitors the voltage using the cFP-2200 with any number of PSC-HAVE-102 installed modules. Each analogue channel PSC-HAVE-102 will correspond to its own state machine which tells you a central database.
I want to create something that does not need to know how the PSC-HAVE-102 s settled in advance. At startup, my software must be able to detect all PSC-HAVE-102 s and dynamically create the State machines for each channel, if I have 1 I-102 (8 analog monitor channels), or the maximum of 8 installed (64 channels to watch).
Right now, I can only understand how to the program for channels that are currently available by connecting to the module in its current condition and click/drag the analog channels in the project window. Is it possible to program for strings that are not there, but could be later? The application of this is to deploy the module on the ground and have the ability to add or remove I-102 s without changing the installed software.
kgolden,
Do you mean that the ini file will be correctly created only if I have the number I-102 s max? Yes, you must have 8 I-102 in your project as part of the goal of the PSC. Forcing him to be included in the. The IAK file and in turn to be defined in the .ini causes. I think you can use the Project Explorer to add modules to the CFP, even if they do not exist physically.
Is it possible to manually edit the file instead? I think that it is possible to manually edit the .ini. I don't know that NEITHER does not bear this manual change. The question would be is there other on the CFP .ini files that contain references to the i/o modules installed?

This seems to be the opposite of what JPA or any ORM package is intended; you would usually the ORM package produce SQL statements based on an object model and a query of high level object, but you try here to feed a sort of a pre-existing query object model. As I said - back. You may want to use executeNativeQuery?
Whenever I am confronted with a situation where a request starts to do involving the unions, subqueries, etc.. I keep the side JPA as stupid as possible. I create a view on the side of the database and that you simply map my entity to this point of view. With appropriate indexing in place which usually performs very well.

Taskflow dynamic array and reset the user interface States
Hi team.
I use JDeveloper 11.1.2.4.
I have a nice flow dynamic bounded task that has a view main activity. Links to view activity change as part of the workflow. The workflow is initialized with a navigation event. The display shows just a table of data corresponding to the navigation event. The table is sortable. It all works very well.
The challenge that I meet is that users do not want details of the sort on the table has persisted between navigation events. So they select NavA, the query executes against ViewA. They select NavA, they query executes against ViewB. The table and the activity of the view are the same. And, during the navigation, in the framework of task flow not related, the display does not actually change in the region. It is updated with the appropriate data, but the genre are also persisted. It feels like the client stores the State of the table that I'm not able to remove the sorting criteria of the Rich Table via a managed bean. Certainly, it feels like what must be launched from the client instead of a managed bean. I don't want to add buttons to view activity to do the reset, because users want this to be triggered by the navigation event.
If I spend a dynamic unrelated workflow and to return to the dynamic workflow, so details are reset beautifully. However, this is not an option for the users.
Any suggestions on the approach would be appreciated.
Thank you
BradWOK, so I had to add this feature to my menu:
public void setResetMainRegion(String regionName){ if (regionName != null && !"".equals(regionName)){ UIComponent mainRegion = JSFUtils.findComponentInRoot(regionName); RichTable table = (RichTable)JSFUtils.findComponent(mainRegion, "DynamicCodeTablesTab"); if (table != null){ List
sc = new ArrayList () ; table.setSortCriteria(sc); AdfFacesContext ctx = AdfFacesContext.getCurrentInstance(); ctx.addPartialTarget(table); } } The thing is that we must find the component, as it is extremely difficult to work with PageFlowScoped managed beans that have been created to support tables. Such a simple fix, it took you a while to understand where the issue should be resolved. It seems that some of these issues have to keep longer appears outside the BTF. Not ideal because this introduces too many dependencies. Trying to minimize as much as we can.
