Can we add properties to existing Entities in JPA

I have a Java web application with Hibernate support. Applications works fine except when I want to add a new property to an existing entity. After a new property is added, there is an internal error. If I delete the database and run the application again, the error disappears completely. Is it possible to add new properties to existing entities? and if so, how?

I have another question related to following class may be that can put more light on my base requirement. I am creating Result item object based on details I found on various KM articles for KM reports. I wonder what is that List executedCommands, object.
public static ResultItem getInstance(RID rid,
                                     Map properties,
                                     List executedCommands,
                                     boolean hadError,
                                     String statusDescription)
Can any one tell me about this List executedCommands and what exactly I should pass there and how it is going to affect my output?

How can i add an already existing iphone to a different itunes account without changing anything on the actual phone...just updating it?

I have an iphone synced to my iTunes account. But I need to add another used/existing iphone to my account to update it. I do not want to sync my emails/contacts/apps, etc. from my computer/iTunes to this new iPhone. This 2nd iPhone already has existing apps and is in use.
Is there any way that I can do this without changing anything on the existing iPhone? All I need to do is update it to the iOS 5.0.1.
Thanks!

Thanks so much for the response! You have been helpful and quick!
It wasn't my phone, hence the reason we didn't want to share/take each other's content (apps, contacts, music, photos, etc.). But the owner's phone hadn't been able to update because of a computer crash/no access to a stable computer. So, I just wasn't sure if we could do an update without sharing content.
But you most definitely answered my question! So, thank you!

Can't add rows to existing spreadsheet Numbers OS X Yosemite

I created a numbers spreadsheet with column filters and also popup menus for some columns I am trying to add additional rows to the spreadsheet I followed instructions from numbers:
Add or delete a row or column at the edge of the table: Click at the bottom or at the top of the table. (Drag the control to add or delete more than one row or column.) You can delete a row or column only if all of its cells are empty.
Insert or delete a row or column within the table: Click the table, move the pointer over a numbered or a lettered bar, click the arrow, then choose a command from the menu that appears.
but the options to add rows are shaded gray so you can't add rows but can add columns. the II for add columns is active but there is a double circle where the = should be at the top of the table.
I am a 20 year windows and excel user but am new to Apple and numbers

Just guessing, but have you turned off the filters before trying to add rows? You can uncheck the box shown here:
After clicking the table, you can find this in the Filter panel at the right after choosing Sort & Filter from the toolbar.

How can I add to an existing path using the pencil tool?

This probably seems like a rather elementary question, but
whenever I draw a path using the pencil tool, reselect it,
hover over the endpoint, and the click and drag to extend
the line off into a different direction, Illustrator will often
(but not always) erase the existing path and leave only the
new one that I drew.
To wit:
In step 1 above, I draw a line with the Pencil tool.
In step 2 above, I reselect the line from step 1, hover over the endpoint, and then continue to draw further.
However, as can be seen in step 3, the line from step 1 disappears after I draw the new path.
I am aware of the pencil setting, "Edit selected paths", and I have checked it to edit selected paths
within 12 pixels for the above example. What I am doing in the above example, and what I
want to do, is to be able to add more paths onto an existing one using the pencil tool,
rather than have a completely new path being drawn every time I lift up my pen to finish
drawing the previous path.
I also realize that I can do this with the pen tool; but the pen tool is a more
precise tool (and somewhat more cumbersome), and I prefer to have more
of the rough-handed look from time to time.
Finally, I also know that I can use the direct selection tool to select endpoints
from two different paths and then join them using the join command;
but this seems to be more trouble than it's worth in many cases, especially
if I want to do it frequently for a more long and complicated line.
Am I expecting too much out of Illustrator?
Is my idea of how to use the existing tools wrong in this case?
Is there some piece of knowledge I'm missing?
I'm on Illustrator CS5, Mac OS X 10.6.8, using a Wacom Intuos4 tablet.
However, I have confirmed the above on Illustrator CS4 for Mac as well.
Any help or comments would be much appreciated.
Jeff

Thanks @rcraighead - the Live Paint process seems a bit overkill for simply adding
a new path onto an existing pencil path, but I did try the first idea you suggested,
which was tracing a bit over the last part of the existing path and then continuing
on to extend the path. It's a bit imprecise because the existing path gets slightly
modified, but it seems to work pretty well all in all. Nice idea indeed - thanks a million.
I also found that in AI CS5, I can use the selection tool to select all of the paths
in this case and then join them using the join command. I thought I needed to
select individual anchor points for this to work, but it actually works really
well, better than I thought. I seem to recall that previous versions of Illustrator
were a lot more picky with the Join command, but then again this might just
have been my lack of understanding.
I'm curious to know what other solutions to the above problem that other users
might have, so I will leave this question unanswered for a bit...
but I will use your initial technique described - it seems to work
pretty well, in absence of other options Many thanks again for your timely help.

Can't add iPhotos to existing page

Of a sudden, I've been unable to add photos to an existing photo page. Whether I drag from iPhoto or the Media Browser, only a placeholder with the iPhoto filename appears on the existing photo page — the photos don't appear, nor does the page automatically rearrange photos as it did in the past. I haven't exceeded the 99 photo limit. What gives? Any suggestions?

Apparently, the problem was due to a series of corrupted iPhoto files. I deleted the image files from iPhoto, re-imported the images and then everything worked fine.

Can't add tracks to existing playlists using iTunes for Windows11.1.5.5

The tried and true method of right clicking a track, selecting "Add To Playlist" and selecting a playlist no longer works. There's not response to the end of the process. I'm just back in the original view of the library. When I check the playlist, the track hasn't been added. I don't know what the purpose of the "check box" is but I made sure the original track was checked before attempting the add.
(I searched for an existing thread here and on the Web but couldn't find where others have posted this issue.)

If you use this feature, as shown in my previous screenshot, then unticking a song will cause it to be removed from your iPod at the next Sync, but left in your Library. Leave the ticks turned on.

The Playlist Folders are a method of grouping Playlists together, making them easier to find. The reason they are shown in the right-click is to make the Playlists easier to find. Look at the screenshot below, all the "Sleep" Playlists are in my "Sleep Time" folder.

Can't add songs to existing playlists with iOS 7.1

Yesterday, I downloaded the new iOS 7.1 update. Tonight I tried adding songs to an existing playlist, and they aren't there. I went though the steps. From Playlists, I tap edit, tap (+) to add songs and then tap on the songs I want to add. Then I tap Done. When I go back to the playlist, they aren't there. Is this a glitch with the new update? Or is there a step I am missing? Please help!!

Ah, it looks like I should have read your title more carefully. Are the files on the PCs that you want to share with your iMac in a shared folder?
If not, follow the steps on this page to set up shares from Windows 7.
If that is already set up, connect to the share from the iMac using this article.

Can I add my existing, licensed apps to my list of 'Purchases' on the Mac App Store so I don't have to buy them twice?

Hello,
I was wondering if I could add my existing, licensed apps to the list of app 'Purchases' that I have on the Mac App Store.
The reason for this is that I recently suffered the inevitable hard disk failure and I had to rebuild my MacBook Pro from scratch (with the help of Time Machine and Migration Assistant, etc.). As usual, I hadn't really maintained my MBP for quite a while and things sort of got away from me, in terms of data, apps, preferences, permissions, users (my personal account, my wife's account, my old work account...), etc.
So I wanted to rebuild my MBP on a clean slate. I like having the ability to quickly download and install just the right apps that I "really" need from MAS safe in the knowledge that:
they are there (assuming they're still available through MAS) with a full description of what they do and when I bought them, etc.
they are going to be in the most up-to-date version,
I'll be able to download and install them cleanly with no corruption from years of multiple user preference changes and permissions, etc.
that they will be managed and maintained (updated) through the same mechanism,
so much more.
The benefits of having apps from MAS are easy to see when compared to going through my downloads folder and emails looking for the latest installers, working out what they're for in the first place, finding the license key in some forgotten e-mail, etc.
I am aware that I can build a clean machine and then restore just the right apps in their most up-to-date version as I had them on my backups. The one thing to say about that is that the apps may have been used and abused once too many times and their preferences, etc. may not be in the most desirable form. It's just not as elegant as the MAS solution.
I realise that not all apps, app versions, or app vendors, are available through MAS. But I still have a fair few apps currently available on MAS that were bought prior to the existence of MAS, prior to them becoming available on MAS, or were bought directly for some other reason (by mistake).
So I wondered if there was any way I could convert my legitimate licenses from simply a direct purchase to one through MAS and have those apps listed under my 'Purchases' list. It would reduce the amount of work I'd have to do, not only to rebuild my machine but also to maintain it.
I cannot find any reference or way of having this work the way I would like it to. But I was hoping that some Apple guru would enlighten me.
I have thought about the possible mechanisms something like this would need to work and I must admit I see some not insurmountable issues (not as much technical as legal or possibly logistical). I realise that MAS is a service in its own right and as such has its own Terms, Conditions and Licensing that may not be compatible with the licenses that I already have. I also realise that when I purchase an app from MAS that I'm paying for the entire service including updates and use on multiple machines that I may own, etc. Obviously I do not want to pay the full purchase cost again for the same app twice, but I am willing to pay a small conversion/upgrade fee to have it managed as part of my 'Purchases' on MAS. Think of it in the same terms as iTunes works. I can purchase music, etc. but I can also add my own CD collection and have it managed by iTunes and store it in the cloud should anything go wrong with my local machine, etc.
So if this is currently not possible, then for the Apple MAS product managers out there, consider this as a suggestion/feedback. I'd be happy to discuss my thoughts in more detail about not only how to achieve this for now but also for the future when you may add existing applications to MAS that people may have previously bought direct and would like to have managed through MAS going forward. The benefits to the users are hopefully clear, but from Apple's perspective I hope that you can see the advantages too, commercially, etc.
PS: I apologise for the wordiness of my query and overuse of 'etc.', etc.

No. Only apps purchased from the App Store can be re downloaded for free including updates.

How can i add songs to a family members ipod without erasing existing songs

How can i add songs to a family members ipod without erasing her existing song list.

For future reference, since I came here for the same reason, I'd like to add to the solution. The link was not complete in explaining how to, but then again I'll just trying to attempt to fill in the gap.
After opening iTunes, on the upper left hand side is a small icon with an arrow pointing down. Click on the arrow and a menu pops out. Click on "Show Menu Bar." On the new bar(Older iTunes File, Edit, View, Controls, etc. bar at the top). Click on View and then Show Side Bar. There you can just click and drag new songs into your iDevice without any problems... hopefully...
Seriously, this helped me, so if Apple finds a way to not allow me to do this simple task of adding purchased songs into my idevices from another computer, I'll have to resort to other means.
The one idevice that's having trouble with is my iShuffle(2nd).

How can I add an existing cfm page to a project?

CFB3 Question: How can I add an existing cfm page to a project? I created a project and copied a file into the project folder but I can't seem to find a way to add the cfm file into the project.

@Carl - Well heck, yes I did... But after reading your response I went back and tried right-clicking on and refreshing different things and what worked was right-clicking on the project name in the Navigator window and then clicking on refresh in that context menu.
Thank you Carl!

Can we add a new attachment to an existing SC from any other custom page in SoCo PO View

Hi Experts,
Need your expert advice on the below requirement.
We have created a custom view in SoCo PO page. There we have a New custom view called Notes&attachement.which contains same value from Notes & attachment of Shopping Cart.
We are updating existing Notes of SC by FM 'bbp_pd_sc_update' and same is reflected in SC of same item guid & same header guid.
Similarly trying to add a new Attachment to already existing attachment. New attachment is reflected in custom page and the describe link is working perfectly. but if come out of SoCo page , lets say in SC the new added attachment is shown but display_url,phio_size etc are not stored properly in DB.
in bbp_pd transaction every thing looks same for new and existing attachment. we are using same FM 'BBP_PD_SC_UPDATE' by passing new internal table of attachment in import statement. Even 'BBP_PROC_DOC_UPADTE' has same result that is attachment is partially updated.
Suppose, SC has one attachment at the time of creation. then adding a new attachment in custom view of SoCo PO page then every thing works fine in SoCo PO page but out of that SoCo PO or in SC the newly added attachment is not properly updated.
I have added mime_type,phio_size,disp_url,file_name,file_ext,ev_content of new attachment in existing attachment internal table and calling above FM for update.
Can we add new attachment outside SC to existing SC ? if yes , then how?
Thanks,
Partha
