Pageflow - data binding for collection size

Assume {pageFlow.students} is a collection. What data binding to use to write the
collection size to the jsp page? The following does not work
<netui:label value="{pageFlow.headers.size}" />
Thanks, Jack

This is a very FAQ on the "taglibs-user" mailing list. The same issue comes up
with using the JSTL, because the JSTL follows the same rules about what it can
access.
A reasonable general solution would be to write a simple class called "CollectionBean"
(and similarly "MapBean"). Put it in a "utils" package. It's constructor takes
a Collection (and a Map, respectively). It has two properties, named "collection"
and "size" (the other would be "map" and "size"). Instead of storing Collections
or Maps, you store CollectionBeans and MapBeans. About the only challenge would
be properly naming the instance variables of type CollectionBean, so it isn't
confusing. I'll leave that problem for you.

Data Binding for Custom Controls?

Hello,
I'm a little bit confused of how to use databinding for custom controls.
I know i can bind a property, as seen here http://help.sap.com/saphelp_uiaddon10/helpdata/en/91/f0f3cd6f4d1014b6dd926db0e91070/content.htm, but how can I map whole arrays?
My problem is the following:
I want to create a custom table control in SAPUI5 (as the default one doesn't provide the neccessary options and properties I need), but I can't seem to find an example how to bind "rows".
There has to be a way to do this properly. All I can think of now, and implemented, is, passing the name of the variable in the model...
var x = new my.controls.complex.table({data: "/status"});
var row1 = new my.controls.complex.columnHeaderRow();
row1.addColumn(new my.controls.complex.column({text: "", rowspan: "2", colspan: "1", content: "FIRST_COL"}));
x.addColumnsRow(row1);
x.placeAt("content");
...my JSON/model looks like:
{ "status": [ {"FIRST_COL": "a" , ...}, {"FIRST_COL": "b", ... }, ... ], ... }
(which should translate into /status/0/FIRST_COL, /status/1/FIRST_COL, ... AFAIK)
... and then I use this variable name by getting the application-wide model and use the variable passed as key for the model... (please note, this code is just a snippet)
       var sapCore = sap.ui.getCore();
            if (sapCore !== undefined) {
             var model = sapCore.getModel().getObject();
             if (model === undefined || model == [] || model == null){ } else {
              $.each(model, function(idx, item){
               $.each(oControl.getColumnsRows(), function(idx, item2) {
                $.each(item2.getColumns(), function(idx, item3){
                 var content = item3.getContent();
                 if (content !== undefined && content != ""){
                  outpLine = outpLine + "<td>" + model[idx][content] + "</td>";
...which still leaves me with the problem of to get an event to react to re-render on changes within the data model, as well as when there would be just an control-specific model, or just a sub-node within a model etc.
So my question is:
Is there a way/best practice to define data binding in a custom control and have a way to react on it, and how to react on data changes within a custom control?
Thanks & KR
Chris

I create a entirely new control, from sap.ui.core.Control.
sap.ui.core.Control.extend("my.controls.complex.table",{... });
I did define a aggregation...
        aggregations : { columnsRows: {type : "my.controls.complex.columnRow", multiple : true, visibility: "public"}     },
...yet I'm still unclear how I work with this aggregation and databinding. I know we can use the bindAggreation functionallity, but since the aggregation is a object (my.control.complex.columnRow) I don't know how my JSON model should be able to bind to that aggregation (as well as how would one be able to cascade a aggregation like this down futher? For example if there is an aggregation in the object of my aggregation?), plus it still doesn't solve my problem of how I can react (for example redraw) on model changes.
Thanks in advance,
Chris

Data Binding for Idiots (me)

Hey everyone,
I've been asked to build a form that is way more complex than anything I've done in the past. I just wanted to ask the experts here a few questions before I get started, to make sure that I don't make any huge mistakes.
The complexity of the form lies in the huge number of nested repeatable subforms, the fact that it's three forms in one (which form being shown depends on a selection from a drop down list), and the fact that the form needs to be designed to export its data cleanly to xml.
As far as building the form goes, I'm comfortable with everything except for the exporting to XML. I've done this a few times, but I'm not sure that the assumptions I've made are correct. I've tried reading the help files, but I'm not sure I'm getting it.
Pretty much, I make use of a ton of subforms in order to make sure that the layout of the form works dynamically. I don't want all of these subforms to show up in the xml import. The way I've been doing it is to set the data binding on these subforms to 'No data binding.' Does this have any impact on how data is saved to the form? If I don't want the value of a field to be exported, can I set it's binding to 'no data binding', or will that cause prevent the values from being saved?
My final question is about the 'Use name' binding. Up until now, in past forms I've made sure that all fields have different names. This form is so large, and has so many similar elements that it would be useful to be able to resue field names in different areas of the form. For example, two of the versions of the forms has a section for associated addresses. The fields in these sections are the same. Can I name them the same thing, so long as they are within different subforms? Or will this cause a conflict when exporting/saving.
Sorry for the long post. In short:
1) What afftect does the data binding 'no data binding' have on subforms and fields, with regards to saved data and exported data? Are there any 'gotchas!' that I should be aware of?
2) What are the guidelines I should follow to ensure that I don't come across any naming conflicts? Do I just need to ensure sibling feilds aren't named the same, or should all names be distinct?
I would appreciate any help that you guys might be able to offer.
- Scott

Scott,
1) No date binding means a form object is not included in exported XML. Data binding has no effect upon saving data when saving a form, the form will contain the data.
2) For me, rule #1 is use a schema and schema binding. It is worth the upfront investment in time. What you see in the schema is what you see in the output data, given a form object is bound to the schema. You can bind a single schema element to multiple form objects if you need to re-use data across sub-forms, also. Rule #2, again for me, is to explicitly define sub-form names to simplify schema binding and avoid name collisions.
I've attached a very simple form (with the schema embedded), the schema and exported xml to demonstrate.

Adobe Form - Data Binding for static text

Hi Experts,
I'm trying to create a new label with Adobe Forms (not interactive).
So I've created an interface with a table LABEL_DATA (import) and many variables (import) and a new Form with Layout.
I tried to bind some text fields with the imported variables und fields from the table, they're all available in the context, but all fields are still empty (preview and print).
Field are Text Fields
Type is : Read Only
Data Binding is : $record.LABEL_DATA.KDMAT
Can someone please help me?
Thank you.
Regards,
David

Hello David,
In your interface, have you declared LABEL_DATA as GLOBAL Data ?
You can fill the table and variables in the INITIALISATION in the interface.
Then you can use the Global table and variables in the form.
In case you are missing some values; you can debug the code in INITIALISATION section. Get the import tables in INITIALISATION and filter the required values into Global Table and variables.
Regards
Sandy

Getting at the data binding for table rows in ADF/UIX

At the highest level, I'm trying to figure out the best way to get spreadsheet-like behavior in a table where some of the cells are editable. The table cells were created using the "model=${uix.current.<columnName>}" mechanism.
I've been able to specify event handlers triggered by the <primaryclientaction> for a table cell component which call into static java methods. But I haven't been able to figure out what binding to use to get at the Java instance for that cell's row in order to use <invoke> to get at non-static methods in the row's view object. The ${uix.current} binding is stale at that point.
Are the table row data bindings just gone after the table is rendered or is there some alternate notation that lets me get at them.
Thanks in advance.

the primaryclient action should pass the rowkey of the current row (${uix.current.rowKeyStr}) as a parameter. This way the server can find the corresponding row on the server in an event handler.

Data Binding for Tree Component

Hi ,
I have to make a tree structure and bind it to a column in a table,
which when expanded should list the rows of the table for the selected column as individual sub nodes of the tree.
So far I am not able to get that done.
Any suggestions how to do it?

If find what I need among ADF Faces Core component, ... the ADF TreeTable (http://www.oracle.com/technology/products/jdev/htdocs/partners/addins/exchange/jsf/doc/tagdoc/core/imageIndex.html).
Unfortunetly It seems quite dificult to integrate ADF or any other 3rd part component with JSC2.

Webdynpro ABAP: data binding for node having subnodes and attributes

Hello,
Problem description:
There is parent node (cardinality 0..n), which has some attributes and also a sub node.
This parent node has to be bound to an internal table. The fields of internal table correspond to the attributes of the parent node. Now if a "bind_table()" method is used to bind this parent node to the internal table, will it work? If there is any other way to do it let me know!
Regards
Sagar

Hi Sagar,
If you use the bind_table() method on the parent node, only the attributes( and not the subnode) of the parent node will get set with the values from the internal table. To set the values for the subnode, u have to use bind_table() method on the subnode seperately.
Hope this helps.
Thanks and Regards,
Sharadha.

Data binding for date chooser

<year>{dates.selectedDate.getFullYear()}</year>
</mx:request>
</mx:HTTPService>
<mx:Script>

In the above wsdl the collection of fintObjInst if of type xs:anytype. From the wsdl, I do not see the xsd mapping for AccountIC which includes Name and Desc. Due to which, when invoking the web service from a different client like c#(by creating proxy business service), I am unable to set the parameters for AccountIC. I am using JAX-WS stack and WLS 10.3. I have already looked at blog http://weblogs.java.net/blog/kohlert/archive/2006/10/jaxws_and_type.html but unable to solve this issue. However, at run time using a tool like SoapUI, when this wsdl is imported, I am able to see all the params related to AccountIC class.
Can some one help me with this.
Thanks,
Sudha.

Did you try adding the the XmlSeeAlso annotation to the webservice
@XmlSeeAlso({<package.name>.AccountIC.class})
This will add the schema for the data type (AccountIC) to the WSDL.
Hope this helps.

Stuck at error with How To Example for Data Binding in Multi-Form App

I have succesfully completed the section "Serial Forms Use Case" by Ralph Gordon's in "Managing ADF JClient Data Binding in a Multi-Fom Application" How To Document. Everything worked as explained.

I'll point Ralph to this question. I can't see a difference between your code and Ralph's. Which JDeveloper version do you use use?

What data binding framework to use for EJB(JPA) - Swing desktop application

Hi!
I am developing EJB server application which mostly uses the same entities and session EJB's both for web and for desktop user interface. While JSF is working nicely, I am stuck with necessity to make decision with data binding framework to use for desktop application - I investigated:
- JSR295 reference impementation at java.net (beans binding)
- Eclipse JFace
- JSR295 implementation at kenai.com (better beans binding)
- JGoodies binding
At present I like JGoodies, but I am not sure whether I am not missing something - I guess - large enterprises should develop a lot of desktop applications as well and what binding framework they are using?

user454720 wrote:

I create them sometimes but they are service tools, not part of the main application framework. Generally you keep everything on the server, web based - this keeps it secure, accessible and contained. With all the web 2.0 javascript toolkits available nowadays you can go quite far creating a desktop experience in a browser, with limitations.

Where are the data-binding frameworks for Oracle Objects?

Oracle offers a few different options for data-binding frameworks to Oracle relational data. Amongst them they include TopLink and the Oracle Application Development Framework (ADF)in JDeveloper 10G. J2EE also offers the EJB standard framework. Both of the Oracle data-binding frameworks appear to work well with relational data but fail miserably when one tries to work with a fully fledged Oracle Object-Relational schema. I have spend much time with ADF but have not been able to create successful bindings to Objects with nested complex objects (such as a 2-level nested object) or objects containing nested tables. TopLink will not even touch Object tables.
Have other people being more successful with this? Do we have to implement our own data binding framework? Does Oracle plan on improving these frameworks to fully support Oracle Objects?

TopLink Runtime supports both fully fledged OX mappings and nested complex objects. These mappings can be setup in the code.
TopLink ADF design time however currently does not have support for OX mappings.
Hope this helps,

How to find and replacing the path (url) given for data binding from type 'datasocket'

Hi everyone,
I'm sorry to pose this question as my own knowledge is still very limited.
I have an assignment (bachelor level). We were asked to adjust a plc program in step7 so that multiple of an existing sequence could be run indepently.
The settings for that sequence are controlled by labview. Sensor data is also viewed in labview.
There is an existing labview VI that was made by someone else before us. It uses 'Datasocket' type for data binding. Because we would like to adjust this VI to be used with the other sequences, we would like to change the original path or URL quickly, as in a 'Find&Replace' solution. Yet the find and replace only works for objects or text, not entries in the properties.
Can someone please tell me if there is a way to do is, without having to use shared variables, as we are not at all known with this type.
Many thanks,
Niels

Dear Niels,
Please find the attached example. I placed 5 controls on the front panel, all with a data socket URL (control 1 = URL1, control 2 = URL2 etc). Through property nodes I did the following;
- I got a reference to the front panel
- with this reference we can get an array of references to the controls on this front panel
- one by one we will read the references and check the data socket URL from the control, we compare this with the URL we are searching
- if found, stop we will use the reference to write a new URL to the control.
Please notice the default values of the controls; it is set to search for URL3 and replace this with URL10, run the VI once and you will see that happening. I also included a sting indicator which will show you the label of the control which we find. Also a Boolean indicator in case we were not able to find the URL.
I downsaved the VI to 8.6, I'm not sure in which version you are working, if you have 8.6 or higher you are able to open it. Hope this brings you further,

[svn:fx-trunk] 9349: * Added support for using getStyle() in Mxml data binding expressions.

Revision: 9349
Author:   [email protected]
Date:     2009-08-17 11:32:37 -0700 (Mon, 17 Aug 2009)
Log Message:
Added support for using getStyle() in Mxml data binding expressions.
In addition to the existing "function return watcher" data binding
functionality, we register to listen for style related change events
when we see a function marked with [Bindable(style="true")].
UIComponent's and TextGraphicElement's styleChanged() will now
dispatch events for "getStyle()" FunctionReturnWatchers to handle.
When null or "styleName" is passed into styleChanged(), we dispatch
an "allStylesChanged" event.
QE notes: mxunit test to follow
Doc notes:
Bugs: SDK-20394
Reviewer: Glenn, Pete F, Peter D
Tests run: checkintests, mxunit databinding
Is noteworthy for integration: only if you want to start using it.
Code-level description of changes:
modules/compiler/src/java/flex2/compiler/as3/binding/DataBindingExtension.java
    Modified generateWatcher() to do the AST equivalent of the
    WatcherSetupUtil.vm change.
modules/compiler/src/java/flex2/compiler/as3/binding/FunctionReturnWatcher.java
    Removed unused isNew variable and added isStyleWatcher variable.
    Modified shouldWriteSelf() to return true if isStyleWatcher is true.
modules/compiler/src/java/flex2/compiler/as3/binding/WatcherSetupUtil.vm
    Modified writeFunctionReturnWatcher macro to add a true arg to the
    FunctionReturnWatcher constructor call when isStyleWatcher() is
    true.
modules/compiler/src/java/flex2/compiler/as3/binding/BindableFirstPassEvaluator.java
    Modified evaluate(Context, MetaDataNode) to skip reporting an
    error for no events when style is true.
modules/compiler/src/java/flex2/compiler/as3/binding/DataBindingFirstPassEvaluator.java
    Replaced insideCallExpression boolean with callExpressionStack
    Stack. The "!insideCallExpression" checks were replaced with
    callExpressionStack.isEmpty().
    Modified addBindables() to handle [Bindable(style="true")].
    Made argumentListStack and resetSet more strongly typed.
frameworks/projects/framework/src/mx/core/UIComponent.as
    Modified styleChanged() to dispatch a "Changed" and "allStylesChanged" from the previous
    parent and add listeners to the new parent when isStyle is true.
    Modified eventHandler to notifyListeners() when isStyle is true.
frameworks/projects/spark/src/spark/primitives/supportClasses/TextGraphicElement.as
    Similar changes to UIComponent.
