JavaScript and Custom Components

hi all,
how can i add <script language="JavaScript" src="../js/mypicker.js"></script> line
to result HTML file for my custom jsf component from encodeBegin method?

XUL implementations and custom components

I've been looking briefly into the myriad XUL implementations and one of my concerns is the ease of incorporating bespoke JComponent subclasses - and also bespoke Border and LayoutManager classes. And then doing things like implementing and using a custom JPanel subclass whilst being able to specify its contents in XML in the same way as a normal JPanel.
Does anyone have experience with achieving the above in any of these, and how elegant is the solution?
I note that Luxor will handle custom components, as will Ultrid - though the latter (sadly, as it looks rather nice) won't work for me as I need to deploy as an applet. Any others? In particular, SwiXML/AT? That looks interesting although the documentation is relatively sparse...
Thanks

Ah - looks like SwiXML has just what I want with regard to the components.

Bindings and custom components

hi, i have created a component that wraps the TextInput
control, but it does not work well with the Binding mechanism.
here is the code:
<vc:myTextInput text="{str}" y="8" tabIndex="0" x="100"
id="in1"/>
and the binding
<mx:Binding source="in1.text" destination="str"/>
does not update the str field, and if str is initialized to a
certain value it would not show on the component,
can any one tell me what i did wrong / forgot to add ??
cheers,
Jaimon

Michael,
ADF Faces does define a default-render-kit ID for its application. For your custom components, you'll need to register your Renderers both in the Basic HTML RenderKit (the default renderkit in the spec) and in the ADF renderkit (which is, if memory serves, "oracle.adf.core".) Once you've done that, your custom components will work fine in ADF Faces. This is a generic problem in the Faces spec - there's no way to add a renderer in all RenderKits.
I'll get a FAQ item added for this issue.

Including JavaScript in Custom Components

What's the recommended way to include large amounts of javascript in a custom component?
I'm working on a calendar component and have the javascript being output in a large writer.write(...), but that writer is outputing about 2,500 lines of javascript.
Instead of doing that could I have the javascript code in a seperate file (stored in my components .jar file) that just gets read and output? What's the best solution?

In case anyone is interested you can do this by adding in HTMLFragments into your grid....
something similiar to.
grid.addComponent(row,col,new HTMLFragment("<script>alert('hello');</script>");

Viewstack and custom components...

Hi,
I have a viewstack with an id of say "myViewStack" Code is
below. I then have a function and do this:
appViewStack.selectedChild=home; or whatever...
I guess i am referencing the container sorta like a switch
statement of different views that I can change by using the
selectedChild functionality? That is how I am doing it, and I am
not sure if that is right although it seems to work *so far*
Any help appreciated.
I am getting an error that "globalBar" used more than twice.
This is a common toolbar I want to use and want it to appear in all
views/screens in the app. How can I do this and not have the
redundant code.
Within that I have this code
<mx:Canvas id="home">
<comps:globalToolBar id="globalBar" width="100%" />
</mx:Canvas>
<mx:Canvas id="Issues">
<comps:globalToolBar id="globalBar" width="100%" />
</mx:Canvas>
Thanks
-Westside

Westside,
Can't tell you for sure whether the
selectedChild code is correct, but I'm using it too, and
haven't had any problems with it yet.
Is there any reason you can't rename the id on the second
page?
E.g:
<mx:Canvas id="home">
<comps:globalToolBar id="
globalBar1" width="100%" />
</mx:Canvas>
<mx:Canvas id="Issues">
<comps:globalToolBar id="
globalBar2" width="100%" />
</mx:Canvas>
I'd confidently say that Flex won't allow you to have two
objects with the same ID. Solely, because you can't access them
both from one name.
Hope that helps.
Oz.

Importing custom components

I just downloaded and installed Update 5 and now I cannot import my custom component.
The new update requires the component packaged as a Component Library File with comlib?? extension. I tried to find any docs on the new packaging scheme but couldnt find any. Can anyone on the creator team please supply the info?
Thanks

The importing components in the help contents has a broken link.
The link is "Creating Custom JavaServer Faces Components for Java Studio Creator:,
http://developers.sun.com/prodtech/javatools/jscreator/reference/techart/JSFcomps_building.html
The link should point to the comlib wiki link. It would be even better if the relevant information on complib and custom components is included directly in the help contents instead of an external url.

That is caused by a problem with the Skype extension for Firefox.

Building JSF 1.2 Custom Components with EL and standard components

Hi all,
I have built custom components in jsf 1.1 with great success but i am finding replicating the same functionality in jsf 1.2 very difficult. I have some conditions for my new custom component.
- Using jsf 1.2
- Must use unified EL, i am using a UIComponentELTag
- iam using jsf standard html components from javax.faces.component.html here in particular i wont HtmlCommandLink.
Essentially i am constructing a real time command menu. I have a backing bean from which i get command names and descriptions values. I wont to then in real time construct a table of links (using HtmlCommandLink) - all this work is to be processed by a custom component. Basically the commandLink issues a command in my backing bean, a parameter (param) is passed with the commandLink, this is later picked up in the backing bean method.
I can generate the table, and all the HtmlCommandLinks, i have simply looped throught and encoded each of them.
What i can do: i can see the table and the HtmlCommandLinks, but the links dont perform any action when i press them.
What i want help with:
I want to encode a HtmlCommandLink in my custom component with a param, traditionally i would set the action but this is now deprecated, and i need to use the setActionExpression method. I have tried to do this but the actions are note fired its simply doesnt function.
Note:
In jsf 1.1 I use to loop through all the HtmlCommandLink and peform their processDecodes method within my custom components very own processDecodes. The same in jsf 1.2 doesnt seem to yield any results.
Can someone give be an example or solution to this? I have read articles on the net and they seem to all discuss jsf 1.1 which i have done and it works, but i am using unifed EL and jsf 1.2 now.
Many Thanks,
Kev

Access Custom Attributes in JavaScript and in Transactions

Hello,
I try to work with custom attributes. I've problems accessing the values in JavaScript and in transactions, but it works fine within .irpt pages.
What's the trick?
For a custom attribute called PLANT, can I write something like this in JavaScript?
var p = ;
Is there a way to access custom attributes in the Link Editor of an Action Block?
Kind Regards,
Matthias

Hi Matthias,
it is not possible to integrate that kind of MII variables in JavaScript like you discribed before.
You are right that this kind of expression is possible in the .irpt file. The reason why it is working in the .irpt
but not in the .js is, that the MII script parser is only replacing in HTML content. Everywhere you have
scripting the parser will not replace the {...} markings (since the curly brackets also show start/end of functions aso.).
Variables to JavaScript
The easiest Way to get those variables is to create hidden fields in the .irpt file that you can access via JavaScript.
For example:
<input type="hidden" id="hidden_plant" value="{PLANT}" />
This will be parsed to (e.g.)
<input type="hidden" id="hidden_plant" value="Karlsruhe/DE" />
Now you can access this value in JavaScript via:
document.getElementById( "hidden_plant" ).value;
Variables to Transactions
To parse custom variables to a transaction you first have to specify corresponding transaction variables in the
transaction itself. After saving the transaction you can map those variables to Parameters in the Xacute-Query-Editor.
Including this transaction to your webpage you can simply assign the required value to the corresponding parameter.
For example if you mapped the Plant variable of the transaction to Param.1 you can specify the information in the .irpt
like:
<applet id="trx_test" ....>
<... />
<param name="Param.1" value="{PLANT}" />
</applet>
Another possibility is to set the value dynamically via JavaScript if you use:
document.getElementById( "trx_test" ).getQueryObject().setParam( 1, "Karlsruhe/DE" );
Native access to user variables via the BLE is not possible (as far as I know).
I hope this is what you wanted to hear?
Best Regards
Sebastian

How to custom skin PanelTabbed and Popup components in ORACLE ADF?

Hi,
I'm new to this framework. I'm trying to custom skin ORACLE ADF tab and popeup components to match with a design provided by my client. But I'm facing challenges in styling them. Does anybody did this before? Or do we have any sample code on the web to follow. Please Guide.
Thanks,
Srini

Hi.
I think that everyone did it before . Take a look into official doc:
Creating and Managing Skins - 11g Release 1 (11.1.1.7.0)
Selectors for Skinning ADF Faces Components
The last link have the full list of Skin Selectors (CSS properties that you can change) of the ADF Components.
There is also an IDE helpful to create Skin call ADF Skin Editor: Application Development Framework Downloads
I hope it helps.

Upgrading packages from 2005 to 2012 : Custom components and delyavalidation woes

Hey folks
I've two specific cases with upgrading SSIS 2005 to 2012
1st : most annoying
I have a custom transformation written in c# 2005. It references sql server 2005 dlls such as from
Microsoft.SQLServer.DTSRuntimeWrap
Microsoft.SQLServer.ManagedDTS
Microsoft.SqlServer.PipelineHost
Those are stored under
C:\Program Files\Microsoft SQL Server\90\SDK\Assemblies
The requirement is to upgrade the package to 2012 and the code as well. Since 2005 was not installed on new server , I copied the referenced dlls from old server , added them back to C# project and rebuilt the Custom components dlls then added to GAC
When I open the packages , they complain about the version
Error 2
Validation error. : The component metadata for "My_Comonents, clsid {874F7595-FB5F-40FF-96AF-FBFF8250E3EF}" could not be upgraded to the newer version of the component. The PerformUpgrade method failed.
So I thought , I can add the dll to the toolbox and add it again. WHen I try this , I get this error
"Could not load file or assembly Microsoft.SqlServer.PipelineHost ,version = 9.0.242.0"
Now I assume this is because I don't have 2005 components installed.
Before getting things messy , what should be the right approach :
a- Should I just leave the custom components dlls as they are and add them to GAC ? but they will still need 2005 dlls , should I install 2005 client components ?
b- I can not change the code of the c# project to use new SQL 2012 components , it's a lot of work. so what should be right approach here ?
That was the important part
2- Validation
Even for disabled tasks , like data flow task , setting delyavalidate= True still doesn't help against them being validated and raising error. removing them will help but I do not want , any workaround ?
Thanks

Thanks a lot Joost , appreciate the feedback
This is what I thought too.
I came to the blog you mentioned , but I wasn't sure how it should be related to my problem. Now I think I'll need to make the code changes.
Indeed , I see some declarations of *****90
public void CreateExternalMetaDataColumn(IDTSOutput90 output, int outputColumnID)
IDTSOutputColumn90 oColumn = output.OutputColumnCollection.GetObjectByID(outputColumnID);
IDTSExternalMetadataColumn90 eColumn = output.ExternalMetadataColumnCollection.New();
public override DTSValidationStatus Validate() {
IDTSVariables90 variables = null;
public override void SetOutputColumnDataTypeProperties(int outputID, int outputColumnID, Microsoft.SqlServer.Dts.Runtime.Wrapper.DataType dataType, int length, int precision, int scale, int codePage) {
IDTSOutputCollection90 outputColl = this.ComponentMetaData.OutputCollection;
IDTSOutput90 output = outputColl.GetObjectByID(outputID);
IDTSOutputColumnCollection90 columnColl = output.OutputColumnCollection;
IDTSOutputColumn90 column = columnColl.GetObjectByID(outputColumnID);
SO I should use 2012 references and start migrating this code over ? is it as easy as so ?
Thanks

Issue with SSIS Custom Components - 64 bit SQL 2012

Hello All,
Our SSIS packages built on SQL 2008 R2 make use of some custom components. These custom components are installed as part of an MSI. The dll's are copied over to the Windows/assemble [GAC Folder] and also to the Program Files(x86)/SQL Server/110/DTS/* folder.
The installation does not copy the dll's to the 64 bit program files folder.
X:\Program Files\Microsoft SQL Server\110\DTS
These packages are executed via SQL Agent jobs on a 64 bit SQL server and there does not seem be any issue.
Now we are upgrading our servers to SQL 2012 and we have a new installer for the custom components as well. The new custom components use .NET Framework 4.0 and when installed the dll files get copied over to the Ms.NET 32 bit runtime GAC folder and also
to the SQL Server DTS Folder in x86. The upgraded packages work only when we set the runtime mode to 32 bit. The packages successfully executes within the 32 bit dtexec utility, but when we try to run the same package using a 64 bit dtexec utility the
process errors out with a component failed to load message. The package moves data between two SQL Server instances.
The custom components have always been built for 32 bit runtime. I can run a older package through the dtexec utility (from the 64 bit folder in program files) and it does work without any issues. After the upgrade the package will only execute on
a 32 bit utility. can someone help me understand this issue?
Regards, Dinesh

Thank you Arthur.
i think we got the answer as well, as the .NET framework 3.0 installer copied the files over to the C:\windows assembly the dtexec utility [32 bit/64 bit] was able to load the components.
Now with the new installer the files are copied to specific runtime gac folders as Arthur has mentioned. The 64 bit utility does not find the dlls in the GAC whereas the 32 bit version will find them.
Regards, Dinesh

Using Google GWT to create (Dashcode) widgets for iBook Author I would like to embed interactive widgets in iBooks using iBookAuthor. The widgets in question started life in Java but GWT has allowed them to be converted to javascript and to run on web pa

I would like to embed interactive widgets in iBooks using iBookAuthor. The widgets in question started life in Java but GWT has allowed them to be converted to javascript and to run on web pages (for example, http://softoption.us/content/node/437 scroll to the bottom). In theory, iBookAuthor can bring in most html5, and much javascript. The technique is to wrap the html in a folder, with 2 extra files, a plist and a default png and then change the extension of the folder to ‘.wdgt’. This is the technique for making Dashboard widgets for the Mac, and Apple even have the Dashcode software to do it. So what you really do is to make a Dashboard widget, then iBookAuthor can import it. So far, so good. And some folk have been doing this, for example http://www.prweb.com/releases/2012/2/prweb9242432.htm http://www.panophoto.org/forums/viewtopic.php?f=64&t=10417&p=158330#p158423 However, if you start with GWT and create a single page with one button and a Hello World, compile it, and get the WAR file (I use Eclipse here)… the Safari browser and others will run it properly (even on an iPad). Then if you wrap it, a proper Dashboard widget is created, which runs properly on a Mac. Then if you go to iBookAuthor and put a custom widget in the Text, then drag it in. It is accepted by the text and shown as being there. However, if you use Preview to look at it on an iPad, it is gone (or was never there in the first place). Anyone any ideas on this? [And iBook Author seems to give no warnings.] The widget is at https://dl.dropbox.com/u/46713473/Test6.wdgt.zip I have bells and whistles that I’d like to get into an iBook!
Thanks for any insights.
Martin

I do have a little to add, which might help someone. Indeed, opening a blank page and dragging the widget straight in seems good in difficult cases. But, actually, I was also able to insert successfully from the Toolbar especially to blank pages. So, it may have been something to do with the columns and stuff like that. Anyway back then the insertion would show in iBooks Author but not in the Preview on the iPad. I moved on to actual Google Web Toolkit output javascript. Basically I had three at hand to try: a Hello World with a button which went straight it, one of moderate complexity, (for example with a built in Lisp interpreter), which also went straight in, and finally a more complex one that initially was rejected by iBook Author. Author complained that there was an unsupported media file (of course, Author does not tell you which one it is, that would be too easy). [Remember, this was a proper working Dashboard widget which could be installed on a Mac]. Among other things I had read remarks about .gif files. When looking through the GWT war directory at the actual javascript etc files, I noticed there were two gifs there one called ‘clear.cache.gif ‘ and a second one called ‘0F89659FF3F324AE4116F700257E32BD.cache.gif’. (Now, there is obfuscation so the numbers here may be different from case to case.) The clear.cache.gif did not seem to be anything special. But the other one is an animation. It is three little boxes that twinkle (rather like a waiting spinning cursor). So, I opened that file and saved it to itself (that picks the top frame of the animation and saves only that, leaving you with an unanimated gif). The resulting widget drags and drops into iBooks Author (and seems to work properly at a quick glance). So, if you are having trouble with ‘unsupported media files’ converting animated gifs into unanimated gifs might help in some cases.

Error while accessing application with custom components

Hi experts,
I have an application (HAP_MAIN_DOCUMENT) of component FPM_OIF_COMPONENT which uses a Webdynpro component with the same name (HAP_MAIN_DOCUMENT). This Webdynpro component (HAP_MAIN_DOCUMENT) uses 2 other components (HAP_DOCUMENT_BODY and HAP_DOCUMENT_HEADER).
For my client requirement, i need to create the custom components by copying from standard components as the UI layout changes are quiet huge and not manageable with the enhancements. To accomodate this i have changed the standard configurations by replacing the standard web dynpro components with the custom ones copied. Apart fomr this there are no changes to the standard.

Heading 2: h2. ST22 - Dump Analysis
Error analysis
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not
     caught in
    procedure "WDDOINIT" "(METHOD)", nor was it propagated by a RAISING clause.
    Since the caller of the procedure could not have anticipated that the
    exception would occur, the current program is terminated.
    The reason for the exception is:
    You attempted to use a 'NULL' object reference (points to 'nothing')
    access a component.
    An object reference must point to an object (an instance of a class)
    before it can be used to access components.
    Either the reference was never set or it was set to 'NULL' using the
    CLEAR statement.
