Make DropdownBox initial state to show blank

Hi!
I need to set the initial value selected of sap.ui.commons.DropdownBox to be blank before user interaction, but without adding any empty items.
Is this possible? If yes then how?
Kind regards for your help
Janis

Hi Janis,
There are two options:
1) play with DOM elements of your list/select
2) make a fake dropdown, kind of button which will call a popover with List inside, see code example here: http://jsbin.com/jujog/1/edit?html,js,output
Please note, that FIORI applications are using 2nd approach.
Regards,
Vladimirs

Spry Validation-text field shows the "required" text even in initial state

Hi,
I'm having trouble with spry validation.
I insert my spry textfied and go to the properties inspector where I choose validate on "Blur" and "submit" for the Required state. I check the required box for the "required state" but the initial state will also have the "a value is required" text. If I try to delete the "a value is required" text from the initial state, the required state won't show this error.
What should I do?
Any help is much appreciated.
Thank you.

Hi, thanks so much for the reply
Well the javascript came with the spry file that I downloaded from the adobe site.
Here is my statement:
<label for="name"><span class="style87">Name:</span></label>
                  <span id="sprytextfield1">
                  <input name="name" type="text" class="textInput" id="name" />
                  <span class="textfieldRequiredMsg">A value is required.</span>                  </span></p>
              <p> <span class="style87">
                  <label for="email">Email:</label>
                  </span><span id="sprytextfield2">
                  <input name="email" type="text" class="textInput" id="email" />
                  <span class="textfieldRequiredMsg">A value is required.</span></span></p>
This is the statement for the submit button:
<span class="clearIt">
                  <input name="send" type="submit" id="send" onclick="MM_validateForm('username','','R','password','','R','name','','R','email','','R' ,'comments','','R');return document.MM_returnValue" value="Send comments" />
                </span><span class="clearIt">
                <input type="hidden" name="MM_insert" value="form1" />
This is the javascript

Suddenly my Nikon Coolpix will not upload on to my 09 iphoto it takes for ever then it just shows blank squares no pics and a message that states it cannot read the JPEG files. Can anyone help me, please. I have never had this problem before.

As a Test:
Hold down the option (or alt) key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?
You could also try reformat the Card with your camera

I think you should probably also read the iPad User Guide. You didn't say what version of iOS your iPad is running, so here's the links to both the iOS 6 and iOS 7 (PDF) versions:

Initial State of Navigation Panel - Automatic not working

Hello,
I have several iViews where I have set Initial State of Navigation to Automatic, which should collapse detailed navigation if there is nothing on it to display. However, it always comes up open even though it is blank. Is there anything else that needs to be down to make it work? We are on EP7 SP14.
Thanks,
Alex

Could you check your Portal Desktop Innerpage to check if there is some other iViews also on the left hand side where detail navigation iView is residing? Sometime another iView named Favorites is added there. So it might be the case though detail navigation is not there still it is showing the blank portal favorites iView on the left side.
To check this Open you portal framework page -> Open Desktop Innerpage -> See if there is anything except Content Area and Detailed Navigation there. Check the Innerpage layout to see where these iViews are placed in side the page.

Adobe, please make a formal statement about "free" CS2

Folks, we have heard the whole gambit of ideas and discussions concerning Adobe's "giveaway" of CS2.
To my knowledge, there has only ever been ONE SINGLE post about CS2 NOT being released for free - and that post was in a FORUM. InDesign Secrets picked up on that one post and repeated what was said there. On Adobe's CS2 download page, there is NOTHING said one way or the other. Forum statements are always on a personal level - they are NOT a professional solution for official announcements, and should not be regarded as such.
Adobe, could you please be so kind as to issue a formal statement?
There are many people out there who would use CS2 if it were released for free - folks who will never purchase the newer versions - folks who normally use only freeware. It would be a great benefit to those folks, and it would increase your popularity, and you might even make sales with those people once they get used to your products.
I, myself have a license for CS3 Premium, CS4 Standard, InDesign CS2, but I would recommend CS2 to other folks to use instead of GIMP or other freeware. In fact, when the word went out, I was surprised and pleased and wrote to my friends. Then I had second thoughts and had to tell them "never mind - I was misled". Now, after reading the posts in this here forum, I am somewhat bewildered and confused.
Please make a formal statement about this!

I do not agree with your examples they can’t be used in this case.
The shop and speed examples just don’t make sense. The digital nature of this whole situation alone makes comparisons like shops or driving-speed-limits impossible. When you enter a shop and take something the object is moved, in this case there is nothing moved! (that’s just one point, there many others but that would make this post too long).
Also realise that the knife cuts both ways.
Ignorance of law applies to both user and provider.
If the user did wat he/she could to make sure that it seemed legit than they have done their part.
If adobe did to make sure then the user/visitor of the site can not simply grab the stuff, than the visitor places him/herself in in “illegal situation”.
If adobe gave the public the false presumption that content could be downloaded for free (NOT moved / stolen) then Adobe is also at fault and put themselves in a position where they can’t just make a statement that illegal activity has taken place on the user’s part.
To my knowledge A EULA is NOT intended when you have a license.
Even though literlally means “End User License Agreement” , it initially can’t be tied with a purchase. That will become clear AFTER you read the EULA. If you want the requirement that an initial purchase is mandatory than you must inform the user before he/she opens the EULA. Adobe has not properly informed the public on the downloadpage.
(You can not use the forum for that)
And what about freeware tools? And promotion based sites which from time to time give away software. They all have EULA’s a EULA is also to inform the user of the circumstances he/she can use the software.
If it is not clear on the website (downloadpage) than how is the user supposed to know if he/she can download and install?
- First off, the site which promoted this are respected sites. And still there are sites wich have not done any retration
(and see the points below about notification and retraction).
- Then you have the downloadpage which has no form of restriction/ID authentication and the serials are right there.
- I installed and read the EULA and at that point it seemed al legit.
And you still have the other points which you still can’t place under “ignorance of law” when the user has done it’s part by checking the below
There was and still is no notification on the adobe download site
Serials are displayed on the adobe download site
The EULA literally states "obtained" not "purchased"
Everything can be registered and will show up in your "My Adobe" profile
No adobe ID is needed to reach the adobe downloadpage
Adobe admitted that the whole thing could be seen as an giveaway
Adobe only used the forum to communicate that it was not intended as an giveaway, but as an way for owners with genuine CS2 license to reinstall because of the de-activation of authentication servers. BUT they never stated that downloading and using this version without a previous CS2 license is illegal.
· IF it is illegal to download and install then adobe would state that literally asap (right at the moment they explained in the forum that this is not for non CS2-license holders). Now there is only silence and adobe forum moderators are not responding to issue directly (an sort of "edict" from the adobe management not to discuss until further notice?)
· Days after this fiasco adobe hasn't taken any precautions to avoid further downloading/misunderstanding. (they still left the page as is, they even removed the requirement of an adobe ID to reach the page)
You cannot use the shop or speed example in this case, pro or against adobe.
The software world is totally different.
There are enough examples where older versions are given away as form promotions, and there even promotions which began “silent’ and then went viral.
And realise that the UK law doesn’t apply for the rest of the world, Adobe realises this and therefore hasn’t made an official statement yet. Not just a forum statement which led to some retractions within certain sites.
The assumption of “Consent of the copyright owner” was given on the moment when the downloadpage went up AND no form of notification was given.
Adobe still hasn’t informed me properly through email that download and install of the CS2 is only valid for users who have a previous genuine license.
”...Where copyright exists, the owner is not required to tell people - it's an automatic right....”
I do not believe this, you must always supply enough/proper information or else how is the public to know?
And I still have these questions
Where is stated on the downloadpage that it is intended for CS2 license holders?
http://www.adobe.com/downloads/cs2_downloads/index.html
· Why is that page accessible for everyone without an adobe ID?
Why Can the content be directly downloaded without even going to the downloadpage without any form of ID authentication.
Why is the EULA not customised for this?
Why is there still no notification on the download page?
Why am I able to register it and it shows up in my "My Adobe"?
Why have the users who have registered this with their full and valid address and email information not received any mail about this
Why is the forum the only communication channel to about this? When and Where will be the official statement? Will this be outside the forum. If not, why not use the website homepage and email adresses of the registered users?
Why are there still no takedowns issued on the sites which still promote this as free?
Knowing that there was no form of proper notification (and still none), how are the people who downloaded, installed and registered this to know that this was not some form of promotion?

How set an initial state for Slide effects

Hi everyone, I would like to use the slide effect like the
collapsable panels, with an initial state "closed".
I used Spry Pre-Release 1.5 Preview
In my first attempt
<a
onclick="Spry.Effect.Slide('MoreOptionSlide',{duration:1000,from:'0%',
to:'100%',toggle:true})" >More Options</a>
The DIV is always "open" and after click it closes and
performes the slide animation.
Also i tried to change some style attributes of the DIV and
restore or change them in the "setup" function of the
spy.Effect.Slide constructor, I thought this function is executed
before animation, but it is executed even without be triggered the
animation.
Thanks,
Richard

Hello Richard,
After you design the page and adjust the element dimensions
as if the element would be in page without the animation to show it
you'll have to set the 'display:none' CSS property on that element.
In this situation the element will remain in page but will simply
be invisible. Something like this:
<div id="MoreOptionSlide" style="width: 300px; height:
200px; border: 1px solid black; overflow: auto;display:none;">
</div>
Now using Spry 1.5 effects you can make this element appear
after the More Options link is clicked:
<a href="#" onclick="effect.start(); return false;"
>More Options</a>
<script type="text/javascript">
var effect = new
Spry.Effect.Slide('MoreOptionSlide',{duration:1000,from:'0%',
to:'100%',toggle:true});
</script>

When I open a document from a database (remote) It shows blank. The database application expects Adove to be used.

THE APPLICATION IS NAMED "Master Control". When I open a document it shows blank and the name is always "version-#.pdf". No matter what the size of any file shows to be around 5kB. I am using Linux Ubuntu 10.04.
If I use MS Windows and Explorer then everything works fine. Can you help?
Thanks

A new tab opens by default as a blank tab (about:blank).
If that isn't the case then an extension has changed that behavior.

Problem in showing blank records in tableview.

Hi All,
The requirement is to show a tableview which is completely(contains no data in any cell) blank. The user enters data as free text.
I managed to create an internal table with blank records and using it for the tableview so that the table view shows blank cells , where user can punch data.
I need to do some validations if the cell is initial(user have not enterd any data and press the button)
Now the problem is that , all cells conatin a SPACE (dont have an idea where it is coming from) and thus cells are not INITIAL.
I tried using condense and replace all occurences of cl_abap_char_utilities=>cr_lf , but the space is not removed.
Any one having any idea , why this space is coming or how INITIALIZE the work area.

How to reset a particular view object alone to it's initial state??

Hi,
My application contains view objects with custom data source implementation. One of my requirement is to reset the particular view object alone to it's initial state. I can't use rollback since it is at Db Transaction level. I searched in forums and finally written the following coding to achieve it. It works fine during sometime but sometimes i am getting the exception oracle.jbo.DeadEntityAccessException: JBO-27101: Attempt to access dead entity in Person, key=oracle.jbo.Key[1 -10 ]
    public void resetPersonViewObject(String voName) {
        Iterator dirtyItr = this.getEntityDef(0).getAllEntityInstancesIterator(this.getDBTransaction());
        while (dirtyItr.hasNext()) {
            Object obj = dirtyItr.next();
            if (obj instanceof EntityImpl) {
                EntityImpl entity = (EntityImpl)obj;
                String state = null;
                byte entityState = entity.getEntityState();
                switch (entityState) {
                case Entity.STATUS_INITIALIZED:
                    state = "Initialized";
                    // Don't do anything
                    break;
                case Entity.STATUS_UNMODIFIED:
                    state = "Un-Modified";
                    // Don't do anything
                case Entity.STATUS_DEAD:
                    state = "Dead";
                    // Don't do anything
                    break;
                case Entity.STATUS_DELETED:
                    state = "Deleted";
                    entity.revert();
                    // entity.refresh(Entity.REFRESH_CONTAINEES);
                    break;
                case Entity.STATUS_MODIFIED:
                    state = "Modified";
                    entity.refresh(Entity.REFRESH_UNDO_CHANGES);
                    break;
                case Entity.STATUS_NEW:
                    state = "New";
                    entity.refresh(Entity.REFRESH_FORGET_NEW_ROWS);
                    entity.refresh(Entity.REFRESH_REMOVE_NEW_ROWS);
                    break;
                System.err.println("State : " + state);
        getDBTransaction().clearEntityCache(getEntityDef(0).getFullName());
        getViewObject().clearCache();
}Questions:
1. How to achieve my requirement? Is there any code correction required?
2. How to reset the row which is actually deleted by the user?
3. The sample code shown above is applicable for all the view object instances which are created from the same entity? What should i do if i want to reset a particular instance of a view object (I may use different instance of same view object at various screens whereas i want to reset only one)
Can anyone help on this??
Thanks in advance.

Hi,
As per my requirement, i use various instances of same view object in various dynamic tabs only. Since each tab has its own transaction, refreshing an EO of a particular transaction will refresh only the VO instances which comes under that transaction. So it will not cause any issue for my requirement i hope.
Requirement: Need to reset a particular entity driven view object instances.
Tried Schema: Departments table of HR Schema. Tried using the Application Module tester.
Code i use:
    // Client Interface method of DepartmentsViewImpl
    public void resetView() {
        Iterator dirtyItr =
            this.getEntityDef(0).getAllEntityInstancesIterator(this.getDBTransaction());
        while (dirtyItr.hasNext()) {
            Object obj = dirtyItr.next();
            if (obj instanceof EntityImpl) {
                EntityImpl entity = (EntityImpl)obj;
                byte entityState = entity.getEntityState();
                switch (entityState) {
                case Entity.STATUS_UNMODIFIED:
                    break;
                case Entity.STATUS_INITIALIZED:
                    break;
                case Entity.STATUS_DEAD:
                    break;
                case Entity.STATUS_DELETED:
                    entity.refresh(Entity.REFRESH_WITH_DB_FORGET_CHANGES);
                    break;
                case Entity.STATUS_MODIFIED:
                    entity.refresh(Entity.REFRESH_UNDO_CHANGES);
                    break;
                case Entity.STATUS_NEW:
                    entity.refresh(Entity.REFRESH_FORGET_NEW_ROWS);
                    entity.refresh(Entity.REFRESH_REMOVE_NEW_ROWS);
                    break;
        getDBTransaction().clearEntityCache(getEntityDef(0).getFullName());
        getViewObject().clearCache();
Issue i have:
1. Add a blank row (Soon transaction has become dirty). Call the resetView() client interface. It gives me JBO-25303: Cannot clear entity cache model.eo.Departments because it has modified rows
2. Modify any row and then delete the same row. Call the resetView(). It gives me JBO-27101: Attempt to access dead entity in Departments, key=oracle.jbo.Key[10 ]
[NOTE: Above code works fine when for simple deletion of rows, modification of existing rows, new rows]

Spry state to show a message for a failed dsMonth.loadData() action

Below is my code:
<script type="text/javascript">
var dsMonth = new
Spry.Data.XMLDataSet("DATA/2008/January.xml", "month");
function ds_setMonth(month){
dsMonth.setURL("DATA/2008/"+month+".xml");
dsMonth.loadData();
</script>
</head>
<body>
<input type="button" value="Set month to February"
onclick="ds_setMonth('February')" />
<div id="DataTable" spry:detailregion="dsMonth">
<div spry:repeat="dsMonth">{@id} {name}
{items}</div>
</div>
In case the file "DATA/2008/February.xml" doesn't exist, I
want the region <div id="DataTable"... that previously shows the
data from
"DATA/2008/January.xml" to turn out blank, and contain a
message "Data for February hasn't been updated yet". How can I do
this?
Thanks for all your helps.

I should mention that in this sample I presumed the file
existed but didn't have any data.
<event>
<date>
</date>
</event>
If the is no file on the server, you can use the error state
to show it.

When I send a pages file from my ipad to my mac i can edit the file but when i try to print it shows blank why

when i send a pages file from my ipad to my mac, i can edit the file but if I try to print it shows blank and will not print anything

Is there a reason you are not storing your Pages documents in iCloud? That would work for both your MacBook and iPad if you choose to use it (assuming your MacBook is new enough to support an OS X version that supports iCloud).
If you choose this method, any updates you make on one device would immediately be made available on the other (once you close the file).
