Designing a view

Hi,
1) While using drag and drop for designing a view, the controls are positioned at pre-defined (by the system) places in the layout. How do we re-arrange the controls on the layout and place them where we want them at design time?
2) Which control do we use as a frame where we want to include multiple labels and input boxes. For eg in TCode VA01 of SAP R/3, there are multiple labels and input boxes arranged in a frame named organizational data.
Thanks and Regards,
Jayesh

Hi Mick,
While using drag and drop for designing a view, the controls are positioned at pre-defined (by the system) places in the layout. How do we re-arrange the controls on the layout and place them where we want them at design time?
When we design the view, the UI element are arranged according to the layout selected. SAP recommends the use of MATRIX layout. Try using it in your view.
Which control do we use as a frame where we want to include multiple labels and input boxes. For eg in TCode VA01 of SAP R/3, there are multiple labels and input boxes arranged in a frame named organizational data
For this reqm, i would suggest that you create a transparent container first, set its layout as matix layout. To bring the UI element in the new line, just set its LAYOUT DATA property as MatrixHeadData.
I hope it helps.

Why is the character style for hyperlinks not displaying correctly in design mode/viewing/output?

I am using RH9 and generating WebHelp, and I needed to globally bump up the font size of just my hyperlinked text. I went into my Style Sheet > Character tab, changed the font size of the various character settings for hyperlinks, and clicked Apply and then OK. Normally, this would change all of my hyperlink text font sizes immediately across all of my topics. However, this time, it made no changes to any existing hyperlinked text, and it only affected new hyperlinks that I subsequently added. For the existing hyperlinks, I can only manually change the font size of the each hyperlink one at a time, but that's crazy (there's 100's in this help).
I can successfully change other characters styles and paragraph styles. This issue only affects the hyperlink character styles. It also shows up in all RH modes - Design mode, viewing, and in the final output.
Is this an indication of a corrupted style sheet or some other combination of events that I have yet to discover?

Hi,
You probably have inline styling in your project overwriting the font size of your style sheet. How are you changing the font size of the individual hyperlinks?
There is a workaround for inline styling: Open your CSS in notepad and add !important after the font-size:
font-size: 4pt !important;
Note that this is a workaround, not a solution. As a solutions you can remove all the style attributes from your hyperlinks to force them to take the CSS styling again.

JSF Design Time View Not working correctly for ADF/JSF components

My project is not using any external tag libraries. It is based purely on ADF core/html and JSF core/html components. The design time view does not show the appropriate presentation, everything is shown as nexted frame containers (I suppose how you would show a component that does not have a visual representation).
If I create a new project and copy my jsp (jsf) pages over they show perfectly. I did this activity and all was going well in the new project and then I lost the design time view again. I cannot tell you what I did to cause the issue, maybe it was a modification to the web.xml as has been suggested in some other threads. Can anyone tell me what I should be looking for that causes this problem, what corrective actions I might take to eliminate the issues

Ok I have isolated this issue. In my phase listener I had this line of code:
private static final Logger _logger = Logger.getLogger(EigRequest.class.getPackage().getName());
and I changed it to
private static final Logger _logger =
Logger.getLogger(EigRequest.class.getName());
and design mode started to work. I guess either of the above works for me although I do not understand why the line works when you run the application but not in design mode.
Moral to the story is if something fails in any one of these types of decorators you will drop into a raw view mode. The question I have is if errors are occuring how do I figure out where they may be. There is no indication that anything is wrong with the exception that you lose most of the design mode functionality.
This was not a compile issue, this was not a runtime issue. It took me quite a few hours of writing a test program to validate that it was not just writing a phase-listener issue; then launching, editing, relaunching the application to find the problem. I will say that a good portion of the code came from a Eclipse project. If you add the offending lines of code while using JDeveloper you do not loose design mode immediately. You only see the problem the next time you start JDeveloper which complicates finding the problem.

Remote images not showing up in design/split view

Just recently, whenever i updated the image location from the
local site to the remote site path, the images don't get loaded
into dreamweaver how it used to.
i'm not sure if i unchecked something. the paths are correct
and they show up when i preview in browser so i know it's not that.
if anyone can help with this it will be great. thanks.

Do you have spaces in your image file/pathnames?

Flash 9 Public Alpha work uncomplete format with Khmer Unicode on design page view

I am trying using your trial product in Cambodia to test the
Khmer Unicode of usp10.dll in system32 of Windows XP Professional
and Windows Vista Ultimate, but I am sad to tell you that Flash 9
Public Alpha did not support with Khmer Unicode in the right format
of Khmer Language. Can you include Khmer Unicode Fonts into your
Flash 9 Public Alpha? Even though Flash 9 Public Alpha has some
error of character spaces with with Khmer Unicode on the design
view, but as you press Ctrl key + Enter to test video, it display
well Khmer Unicode Format. Please try correct more on the design
page view, I hope Flash 9 Public Alpha will fully support with
Khmer Unicode.
Khmer

Thank you and best regards,

In IE it shows as a blank page (white), in Firefox it's all there. I'd suspect a CSS issue.

Design & Split View Unavailable

I will apologize up front for the length of this post. I
wanted to give as comprehensive a picture as possible.
I am running v. 8.0.2 on a OS X (10.4.8 - "Tiger"). I'm
working on an intranet site using the company's newly approved
template. Until a few days ago, I was able to see the files (*.stm)
in any view I wanted. Now I cannot see the files in anything but
code view. I can remote to a PC with Dreamweaver 8 and it can see
the files in Design view - the header includes are garbled junk,
but the rest of the page is fine. Two things have changed and I
don't know which is the culprit because they both happened since I
last viewed the site on my Mac version of Dreamweaver.
1. The server files were moved from a "physical" Win2003
Server to a virtual machine. The effect of this is that I now have
to mount the volumes using Terminal because Finder cannot access
them. Tracking down how to mount the volumes is why I haven't seen
them on a Mac for a while. (Don't know why FInder cannot "see" this
particular VM, it sees other ones, but the admin is not interested
in fixing it.)
2. My .NET developer moved the support files and pages for a
class calendering and registration application. (VB.NET 2.0). The
file extension used for the .NET app is .aspx.
I've been scouring the Discussion groups and can't find
anything like this so I'm posting. Some of the ideas I've tried
based on similar posts:
1. Checked to see if .stm is in my extensions.txt file - it
was,
2. Checked Style Rendering to make sure "Display Styles" is
checked - it is.
3. Checked extensions listed in "Open in Code View" text box
to make sure .stm is NOT listed - it wasn't. Just for kicks, I
added it, quit Dreamweaver, launched, deleted, quit Dreamweaver and
launched again...no good.
I'm out of ideas...anyone, anyone?

No Design/Split View?

Ok... sorry to sound like a rookie here, but one of the few
times I really want to use Design View I cant seem to get it to
work. Let me explain...
I am a long-time hand coder, and still hand-code most of my
pages. I have a page that I have hand-coded that contains an image
that I would like to create an image map (link) for. However, I
cant seem to get the Design and/or Split views to work. The buttons
on the nav bar are greyed out and the selections are unavailable
from the drop-down app menus. Here is some further info:
1. Here is the URL to the page I am working on:
http://stage.novussententia.com/walkofhope.
2. I am developing this on a remote server... but the server
is local to my network.
3. I am using server side includes
4. Here is the actual code from the page since I am using
SSI's:
<%
pStr = "private, no-cache, must-revalidate"
Response.ExpiresAbsolute = #2001-01-01#
Response.AddHeader "pragma", "no-cache"
Response.AddHeader "cache-control", pStr
%>

BOXI3.0 Universe Design using view or query in SQL

Hi. Alias here.
I would like to know what are the effect to the BOXI3.0 or SQL performance if:
1. We are using view or query in creating the universe?
2. Is it the correct way of creating the universe only from tables?
3. If need to do combination between tables and views?
Hope you all can reply to this matter.
Regards,
Alias

Hi Alias,
Designer has the capability to import tables and views you cna use in the design of the universe. Furthermore, you can also create a derived table in the universe - in simple terms it is much like a view, but the code is in the universe availble to the universe designer.
With all this available to you, it is pretty much up to you how you want to tackle the design. I would say first prise is using the physical tables in the databse, then move to using a view and if there are certain restrictions on the designer, use the derived tables.
Remeber this, at the end of the day, any SQL code generated or used is passed down to the database to be processed, may it be the query from the universe directly on the tables or by means of the views or derived tables - the database server will need to crunch through it all - and this is what will determine your performance.
Regards
Jacques

Suggest to better design the view?

Hello Experts,
we are in the process of designing a huge User Interface using WDJ for our client. And this would contain many views which has to render few UI Elements based on the End Users action. For eg., in a view there will be a few default elements displayed with a Button to Add a couple of Table UI Element and a couple of Input Fields upto 5 or 10 times.
I just want make sure to keep the view/component/custom controller lite , how could I design this particular view?
Any thoughts or ideas or suggestions are very much helpful.
Thanks in advance
Balaji

Hi,
If you know the number of UIs in design time, Please create them in design time. If not go for Dynamic UI Generation.
I would prefer Matrix layout over Grid layout. Check out the following link for more info

DW CS4 - Design/Live view not available with PHP

I am working with PHP documents but both Live View and Design View are grey and unavailable with PHP documants open. I am using MAMP and have set up local info and testing server in the site set up dialog several times myself and with the help of some web search with no difference. Any thoughts on what may be some things to check would be greatly appreciated.

Hoooo Leeeee Moe Leeee...
QUOTE"
Have you changed your preferences to open PHP pages in Code view?
In the File Types/Editors category of Preferences, if you add .php to the list of file name extensions in "Open in code view", it disables Design view and Live View for that type of file.
I can not believe I searched for over 30 minutes to find out that adding .php to this field; disables one of the ONLY reasons I purchased CS5.
Just for giggles, why would it be designed like this? "Open in code View" = a prefrence to what screen type you see, not, "I want to disable CS5 to pre CS2 version"...
Well, just my two cents. Now that I know, I will never do that again... So, Next question. Is there a way to make Dreamweaver by default open in code view, without setting the tempting box to do it for you?
Thanks ahead of time. By the way, I am greatful that someone has the answers! and I am glad that person is you sir = Enter the Adobe Expert.

Design / code view problem

Hello, I have been using DW for a while now. I only use code
view. When I first installed DW it asked for a default layout which
I assumed had nothing to do with the viewing of code vrs design,
just the layout. I chose coder layout.
Now I am in DW and I need to look at the design in real time
because I am having an issue that is causing me to go back and
forth between browser and DW and it is getting old. So I looked up
at the top where the toolbar is and design and split buttons are
greyed out and inactive for me. I thought this was odd so I created
a new basic HTML page to see if it would allow me access to these
buttons but again, no.
If I go to view menu same thing. I can only check code view.
I can however go to the window menu and change the layout to
designer, dual or coder but all this does is undock many of the
panels. I still cannot see the visual element of my code.
Can anyone please help me with this problem? At its most
simplest form, I created an HTML page that says Hello World and I
would like to be able to see this in both code and design view or
switch easily between the two. But as of now, it does not seem like
I have this ability. Again I am using DW 8
Thank you for any help

I see you are using DW8. OK....
Also, changing from coder to designer won't affect the split
view.
Have you tried reinstalling? Has DW always been this way that
you recall?

BPEL Designer - Monitor View for BAM

Hi peers
Is there anything special you need to do in JDev to enable the Monitor View in the BPEL Designer? We only have the BPEL and BPA options to choose from. The doco implies it should just 'be there'? We're using 11.1.1.1.0 of JDev.
Thanks
Dennis

Design Manager view broke...

Has anyone ever seen this in Design Manager.
I've seen it a couple of times now, in OnPrem and Office 365/SP Online.
I've no idea what or why though - the screen shot is a brand new site collection on my dev box.
It's displaying the list view of the master page gallery, but all files and folders and no title/name.

Hi,
Can you disable and then again enable publishing feature at both site collection level and site level? Make sure you have backup of your custom master pages if any.
Let me know if it works.
Thanks,
Avni Bhatt

... Design and View Issue

Hi All,
I have got stuck over a strange requirement.
There are 2 tables which are identical in structure. Both tables displays the same information.
Table structure is
TeacherID TeacherName param1 param2 param3 param4.
Now if the teacher has a special trainingcourse approved, their record is moved to another table. where the value of TeacherID, Teacher name remains same , but Any of the parameter values can differ.
The issue comes when we need to generate the report. The report should pick the value of parameters from Table1 if the teache has NO trainiing, and it should pick the record from Table2 if the teacher has the Training.
How to create a View which will display the information. as Decode function is not working in a Create View Command.
I have put a Flagg field , which turns to 1 whenever the teacher gets the training , and the record is moved/copied to table 2.
But how come we be able to display the report like below.
teacheId Teachername param1 param2 param3 param4...
xxx xxx xx xxx x xxx
where the value should be picked from Table 2 if there is a training , otherwise should be picked from Table1.
Kindly reply early, and suggest anyother possible design ..
Looking foward to your earliest feedback with this difficult design
Regards

There are a couple of options. Unless your tables are pretty small, I would porbably go with:
SELECT teacherid, teachername, param1, param2, param3, param4
FROM table1
WHERE flag <> 1 -- or possibly IS NULL depending on what you put in
UNION ALL       -- for a teacher with no training
SELECT teacherid, teachername, param1, param2, param3, param4
FROM table2Another option would be an outer join and DECODE or CASE. Something along the lines of:
SELECT t1.teacherid, t1.teachername,
       DECODE(flag, 1, t2.param1, t1.param1) param1,
       DECODE(flag, 1, t2.param2, t1.param2) param2,
       DECODE(flag, 1, t2.param3, t1.param3) param3,
       DECODE(flag, 1, t2.param4, t1.param4) param4
FROM table1 t1
   LEFT JOIN table2 t2 ON (t1.teacherid = t2.teacheridA third possibility, particularly if the number of trained teachers is relatively small would be scalar sub-queries like:
SELECT t1.teacherid, t1.teachername,
       DECODE(flag, 1, (SELECT param1 FROM table2 t2
                        WHERE t1.teacherid = t2.teacherid), t1.param1) param1,
       DECODE(flag, 1, (SELECT param2 FROM table2 t2
                        WHERE t1.teacherid = t2.teacherid), t1.param2) param2,
       DECODE(flag, 1, (SELECT param3 FROM table2 t2
                        WHERE t1.teacherid = t2.teacherid), t1.param3) param3,
       DECODE(flag, 1, (SELECT param4 FROM table2 t2
                        WHERE t1.teacherid = t2.teacherid), t1.param4) param4,
FROM table1 t1You would need to test with your data to determine which was better.
