How to get the meaning of the regular expression?

Hello All,
I want to know how to get the meaning of the regular expression?
The requirement is i need to get the regular expression for some of the attributes and if the value is not matching with that regular expression then i need to give the popup saying the limitation of the attribute. but i need to give the pop up with the user understanding format.
Like "please give a to z or 1 to 9" like that.
So is there any way Java will help me to get the meaning of the regular expression?
Thank You!
Arun S

I'm not aware of any such tool or library.
Also, it would be a terrible "explanation", because regular expressions (similar to other programming languages) have their own "style" of defining what to enter and that usually doesn't translate well into natural language.
For example the regex "[a-z][a-z0-9]*\s+[a-z0-9]+" could be translated as "a to z, followed by zero or more characters from a to z or 0 to 9 followed by any amount of whitespace followed by one or more characters from a to z or 0 to 9".
Or you could simply say "Please enter two alphanumeric words, the first one must not start with a number".
My suggestion: store/configure the human-readable description together with the regex. Don't try to automate it.

How to write the regular expression for Square brackets?

Hi,
I want regular expression for the [] Square brackets.
I have tried to insert in the below code but the expression not validate the [] square brackets.
If anyone knows please help me how to write the regular expression for [] Square brackets.
private static final Pattern DESC_PATTERN = Pattern.compile("({1}[a-zA-Z])" +"([a-zA-Z0-9\\s.,_():}{/&#-]+)$");Thanks
Raghav

Since square brackets are meta characters in regex they need to be escaped when they need to be used as regular characters so prefix them with \\ (the escape character).

Getting the regular expression from the given text

Hi
I need to develope an application which can convert the given text into the regular expression. I need that when i enter any text in textarea that should be translated into regular expression in another panel. but i could not find the method or technique which can do so. plz help me to resolve this issue.
Thanks Imran khan.

well, there are an infinite number of regular expressions for an arbitrary piece of text, so you will have to qualify in your mind what the purpose of the regular expression is.
For instance, it is trivial to create a regex for a string just by copying the input text, and inserting \ before any special characters. But this pattern would probably be quite silly.

How to get the el expression foruserrole in custom template jspx from secob

Hi All,
I am working on webcenter template customization .
My requirment is based on the user roles i want to control the visibility of certain webcenter tabs and link .
I foundd a security object which holds all user related data information .
Like
"#{security.userDisplayName}"
"#{security.authenticated}
is it possible to get such a kind of el expression to access useroles what we defined in OID .
Thanks ,
Arun.

#{securityContext.userInRole['yourRole']}Should do the trick.
Edit: just notice you put the roles in OID... Don't know if this is working for OID but maybe you should integrate OID with weblogic as a provider. This way the roles should be propagated to WLS. If you already have integrated OID and WLS, than i think this EL should work.

I don't know but have to loop for the Matcher object and count. Too inconvenient !Since I don't understand what you mean by "the matched amount" I can't tell if this is correct or not.
You could always produce an SSCCE and ask how it might be improved.No,no,no, just means matched substring, like 2 is the matched amount for "aaabbaa" by "aa".

How to dynamically get the SOM expression of a field?

As a follow up to the note below, I would really appreciate any help as of how to get the SOM expression of a field dynamically, by this, I mean how to get the SOM expression of a field at running time using JavaScript.
Thanks,
Isis
That does make things clearer. You will have to save the change information in the XML. I realize that you don't want to save an xml node for every field, but there is a better way. You can use scripting to add data nodes to the XML data in the form. I'm thinking of the following:
Include an empty container node in your XML schema: <HighlightedFields></HighlightedFields>
When a field is changed, in the field's change event call a common script: HighlightChangedField, passing in the object. The script will highlight the field (set the border a certain color or whatever). It will also add node underneath the HighlightedFields data node with the SOM expression of the field. The SOM expression is the "path" of the object in the form heirarchy, sort of like an xpath. So if you have a subform named Subform1 and you change the Name and Address textfields, you might end up with something like:
<HighlightedFields>
    <HighlightedField>
        <SOMExpression>xfa[0].form[0].myform[0].Subform1[0].Name[0]</SOMExpre ssion>
     </HighlightedField>
    <HighlightedField>
        <SOMExpression>xfa[0].form[0].myform[0].Subform1[0].Address[0]</SOMEx pression>
     </HighlightedField>
</HighlighedFields>
The upside of this is that you only store XML nodes for what is changed instead of needing a specific XML node for each field. The downside is that you will need a call to the common script in every field's change event: HighlightChangedField(this);
Now, to make this work when a form is loaded the next time, in the initialize event at the topmost subform in the hierarchy you add a script that walks the HighlightedFields data node, and for each HighlighedField entry you highlight the contained object. You can get a reference to an object using its SOM expression, so just take the SOM expression from each entry and do an xfa.resolveNode(SOMExpression) to get the object, then set whatever attributes you want to highlight the field.
The big issue I see with this would be if you have dynamically added objects on your form. In that case you would probably need to store the instance index along with the SOM expression for each changed object, then use that instance number when highlighting on form load.

As a follow-up, I had said I would try to put together an example for you. The setting of the change indications and the highlighting of the fields is not a problem, but I did have an issue that perhaps one of the experts on the forum can help with:
The problem is how to detect a change in a text field without a lot of overhead. You can't just place a call to the highlight method in the Exit event without checking for a change, since the user can just tab from field to field without changing anything. Unfortunately the properties that show the old text and new text of a field are not valid on the Exit event. An alternative is to use the Change event, but with a text field the event fires for every character typed. This seems like a lot of extra processing..
Anyone know a better way? I went as far as using the extras collection on fields to hold the last value, but that adds a lot of complexity since it needs to be set to the initial raw value when the form is first loaded. I'd like to find a solution that doesn't require a lot of code to be added to every field on the form.

The same is happening for me. Today I decided to reboot my PC because it was acting up a bit, go figure, and then for some reason at the same time the PC was restarting my macbook froze. I had to do a reboot with the restart button but then all that came up was a gray background and in the middle of the screen was a darker gray folder with a white question mark in the middle of it, blinking. I can't imagine why the restart would've affected my macbook. After finding information on how to fix this, I tried all of the steps that were given about using the mac OS X disk to use the first aid utility to fix it. When using the Disk Utility option whenever I select my hardrive and am in the First Aid tab, the only button I can use is the Verify Disk Permissions. The other three buttons, and namely the most important Repair Disk button, is/are not selectable (grayed out). I then tried resetting the PRAM the way they also said with the command + option + P + R and waited for the second startup sound. After that I gave the Disk Utility a second try, but still nothing. And now if I try to just reinstall the OS completely I can't even select a destination volume on the third step (Select Destination). Apparently this means i'm SOL.

How to get the return values from a web page

Hi,
What kind of web page do you have? Do you have possibility to for example make RFCs? Then you could trigger events (with parameters that could "return" the values) and the workflow could react to those events. For example your task can have terminating events.

How to get the values and attributes of Longlived processes by using ProcessID.

Hi Experts,
For every process we creates, LC ES2 creates processID.
we know that if you creates a long lived process, all the values which are in proces will be stored some where in DB.
Here my requirement is by using processID I need to get all/some values/variables stored in database.
I am not able to get values using processID. Here I don't have clue on how to get the values.
Please tell me how to get the same by using Process Management. Link/guide would be helpful
Thanks
Praveen.

Searchable means you can put a filter criteria on it (e.g. where amount > 50000)
Visible means you can add have this column returned as an output (and therefore you can add it as column in listview and see it in Task Details).
These two attributes were provided so that queries could be done against the process variables, but the exact contents of the variables are not allowed to be seen.

How to get the selectedIndex from a combobox made by classFactory?

Dear All,
I am trying to get the selectedIndex or selecetedItem.banda_id when changing a combobox that is created by classFactory and it is inside a datagrid.
The code I have is:
MXML:
<mx:DataGrid width="100%" height="100%" id="salas_fin_dg" editable="true">
     <mx:columns>
<mx:DataGridColumn headerText="Titulo" dataField="titulo" editable="false" width="250"/>
<mx:DataGridColumn headerText="Data" dataField="start_dt" editable="false"/>
<mx:DataGridColumn headerText="Dur" dataField="duration" editable="false" width="40"/>
<mx:DataGridColumn headerText="Banda" dataField="banda_nome" editable="true" itemEditor="{combofac}"/>
<mx:DataGridColumn headerText="$ Ensaio" dataField="total_ensaio" editable="true" itemEditor="controls.NumericInput"/>
<mx:DataGridColumn headerText="$ Bar" dataField="total_bar" editable="true" itemEditor="controls.NumericInput"/>
<mx:DataGridColumn headerText="$ Loja" dataField="total_loja" editable="true" itemEditor="controls.NumericInput"/>
<mx:DataGridColumn headerText="$ CC" dataField="total_cc" editable="true" itemEditor="controls.NumericInput"/>
<mx:DataGridColumn headerText="$ CH" dataField="total_ch" editable="true" itemEditor="controls.NumericInput"/>
<mx:DataGridColumn headerText="$ DI" dataField="total_di" editable="true" itemEditor="controls.NumericInput"/>
<mx:DataGridColumn headerText="$ Pend" dataField="total_pend" editable="true" itemEditor="controls.NumericInput"/>
     </mx:columns>
</mx:DataGrid>
Script:
private function getSalasFinHandler(event:ResultEvent):void
salas_fin_lst = new ArrayCollection(event.result as Array);
salas_fin_dg.dataProvider = salas_fin_lst;
myservice.getBandas();
combofac=new ClassFactory(ComboBox);
     combofac.properties={dataProvider:bandas_lst, labelField:"banda_nome", prompt:"Selecione"};
I am using Remote Object to get the data from a DB, and it is working properly.
As I will update the datagrid cell values, I would like to update them on the DB.
In order to do that, I would need to access the banda_id value, that is part of the combofac dataprovider, I mean that this dataprovider has 2 columns, being banda_nome and banda_id.
The question is how to get the banda_id value, when I change the comobobox?
Many thanks in advance,
Gines

Dear harUI and kolinitcom,
Thanks for the your prompt response and guidelines.
I went to research a little bit more on the itemEditEnd and found a way to access the data inside the combobox.
The code for all application goes below. If you click on the button, it will show you all the datagrid data, plus the ID of the combobox when changed.
Thanks again,
Gines

How to get the last error for while loop?

How to get the last error for while loop? I just want transfer the last error for while loop, but the program use the shift register shift all error every cycle.

What do you mean by "get" and "transfer"?
If the shift register is not what you want, use a plan tunnel instead.
Typically, programmers are interested in the first, not last, error.
Can you show us your code so we have a better idea what you are trying to?

As far as I understand you want to get the display value instead of the index
I use this code
    public void StatusChangedListener(ValueChangeEvent valueChangeEvent)

        BindingContainer lBindingContainer = lBindingContext.getCurrentBindingsEntry();
        JUCtrlListBinding list = (JUCtrlListBinding) lBindingContainer.get("Status");
        int newindex = (Integer) valueChangeEvent.getNewValue();
        Object row = list.getDisplayData(); // Wichtig um die liste zu laden!!!!
        Row lFromList = (Row) list.getValueFromList(newindex);
        Object lAttribute = lFromList.getAttribute("Value");

How to get the latest credit limit values per each customer in the report.

Hi All,
Can anybody give me an idea on how to get the latest credit limit values per each customer in the report.
I have below requiremnt.
I have cube which is having transactional data on document and customer level .and it also having master data info object in the cube which is credit management view having all the customer numbers .
This credit management view is master data info object having credit limit key figure as attribute.These credit limit are per each customer.
So we need these credit limits in the report as dynamic values .(I mean whatever be the current credit limit in the master data table for that paricular customer that should show up in the reporting).
one more thing these credit limits should roll up correctly at the HTR level.
One HTR having number of customers .
for example HTR 100 can have customer number 200,300,400.
Those 200,300,400 customer credit limits should roolup correctly at the HTR 100 level.
Example below :
Cube DATA :
HTR Customer Doct number Credit managment view
100 200 10001 200
100 200 10002 200
100 300 10004 300
100 300 10005 300
100 400 10006 400
100 400 10007 400
100 400 10008 400
Master data tabel (P Table)(Credit managment view)
Credit managment view Credit limits
200 1000.00
300 50000.00
400 90000.00
Please remeber :
We can not make these credit limits as navigational becasue these are keyfigure attributes not characteristics.
one more thing we can not make them as charatistics because we need use these credit limits to derive other calkculation. so it is not possibel to derive calculations on charactristics .

Create a formula variable of type replacement path with reference as attibutes of Credit management view and choose your key figure credit limit,say zcredit.
Now create a formula or CKF and use zcredit.
This should display the credit limit in your report as normal key figure.
I didnot get this part "one more thing these credit limits should roll up correctly at the HTR level.", may be the above will solve this too.Try it.
Hope this helps.

So we need these credit limits in the report as dynamic values .(I mean whatever be the current credit limit in the master data table for that paricular customer that should show up in the reporting).
one more thing these credit limits should roll up correctly at the HTR level.
One HTR having number of customers .
for example HTR 100 can have customer number 200,300,400.
Those 200,300,400 customer credit limits should roolup correctly at the HTR 100 level.
Example below :
Cube DATA :
HTR         Customer     Doct number Credit managment view
100            200                10001             200
100            200                10002             200
100            300                10004             300
100            300                10005             300
100            400                10006             400
100            400                10007             400
100            400                10008             400
Master data tabel (P Table)(Credit managment view)
Credit managment view       Credit limits
200                                           1000.00
300                                           50000.00
400                                           90000.00
Please remeber :
We can not make these credit limits as navigational becasue these are keyfigure attributes not characteristics.
one more thing we can not make them as charatistics because we need use these credit limits to derive other calkculation. so it is not possibel to derive calculations on charactristics .
