How to do batchreading of collections in EJB3

Hi!
I'm trying to migrate a small example from using ordinary toplink mapping in the mapping workbench to EJB3. There are some collections in that example that I want to be read as batch. (It's a check box called "Batch Reading" in the mapping workbench). Is it possible to do this in EJB3 and how? It would be very useful as it has proven to me to be a very effective way of limiting the number of roundtrips to the database.
Regards,
Bjorn Boe

Beautiful!
One other thing that I've noticed is the lack of support for configuring caching on the mappings. The closest I've come to documentation on this has been to configure bean instance pool timeout in the orion-ejb-jar.xml, which I hope was documentation on something else. Do you know if there are any plans on doing something there or other ways to get around this that won't involve using the mapping workbench for mappings?
Regards,
Bjorn Boe

How can I exit a collection window and return to parent folder?

I would "love" to have a place where I could ask the simple questions like this that come up and seem so simple to those who know, they don't mention the details I need like how to close a working collection window and move back to the parent folder of that collection.
I've been stuck for two days (it happened before) in a window (library module) with a collection of 8 photos. I cannot find any way to close that window or go back to the library collection of hundreds of photos from which it was chosen. It's very frustrating to be stuck in this window, perhaps forever?
How do I close these windows. Isn't there a "back" button?
I started in Photoshop 3, then 5, then 7, then stopped renewing due to difficulty learning PS until the Adobe CC became available with the many tutorials. It was great learning how to make a collection, but the tutorials didn't mention how to get back to the main folder where the collection was chosen. So again, I"m stuck at an even lower level of functioning than with photoshop alone.
I had to copy a photo and open it separatly in Photoshop just to be able to work on it. Yesterday I could "edit in Photoshop cc" with right click. Today, it won't even do that.
I suspect now two things are working to prevent me from working properly on my photos but have no clue how to fix this.

In the library module, left-hand panel, there are different sections or tabs. Collections is one of those tabs near the bottom out that panel. If you scroll up in that panel you should see other sections, one of which is "Folders". If that isn't showing, then right-click on the Collections section heading and make sure there are checkmarks in the sections that you want to have displayed. To return to the folder you need to go to the folders section and find the folder in your list.
Another way to return to a folder is to click in the area in this illustration:
Doing so will present a list of folders that you have recently been inside of. You can click on one of those folders and return directly to it.

How do I put a collection in a readonly report on the fly

How do I put a collection in a readonly report on the fly??
Thanks, examples if you can please.

Doug,
You can simply create a report region and use that to display the records in the collection:
SELECT
c001,
c002,
c003,
FROM
apex_collections
WHERE
collection_name = 'YOUR_COLLECTION_NAME'Thanks,

How best to use catalogs, collections etc

I wonder if anyone can help out on a newbie question about how best to use catalogs, collections, etc
Let's say I shoot an event A. I take loads of photographs, which I import into Lightroom. I choose some that I like and I flag them. So far so good.
Then I do the same for events B to Z.
Now time passes and I would like to go back to all of the photographs from event C, and just select them for further processing.
Is this what collections are for? Should I be making "All Of Event C" into a collection, then in the future I can come back and just ask to show the photographs from a given collection?
Many thanks,
regards,
/alan

You can do it that way.
>Should I be making "All Of Event C" into a collection, then in the future I can come back and just ask to show the photographs from a given collection?
That would work. Or you could include a specific job identifier into the
metadata (I believe there's an IPTC field specifically for that), and
then make a smart collection that isolates just that value of "Event C".
If you use the same star ratings for all jobs - 1 is finished, 2 is
further work needed, 3 is review, etc - you could further winnow it
down. And that way, you don't have to worry about removing photos from
one collection or another; the smart collection will automatically add
or remove them from view, based on the criteria and the current values
of the photos.
With collection sets, you could have a set called "Event 1". And within
this set could be the various collection criteria mentioned above.

How do I edite my collection description after it's already exported (in HTML)?

Hello,
I've been using Photoshop and Lightroom for a while not. Both are amazing, and I'm even now using Dreamweaver. Anyway...now, I'll get to my question:
How do I edited my collection description after already having exported my Lightroom Gallery? For one, I noticed a spelling error in the title, and I also want to edit the description a little bit more without having to re-export it from LR again and having to Re-publish all again. (I manage to use the file codes to change a few other things using DW, but for the life in me I cannot figure out how to change the Description).
I guess this is actually a coding question, not a question about LR itself, but I'm hoping some people who've used and tweaked LR galleries will understand my plight and help me. I would appreciate it very much.
Oh, and if it makes any difference, I'm using The Turning Gate free gallery because it's HTML5. I wasn't sure if any of the other LR5 CC ones were HTML5, that's why.

Two options.
Export the gallery again but to your desktop. Find the Index page with the description on it and edit to the way you want. Dreamweaver will work fine but a text editor will suffice. Save the page and upload that page only- replacing the one online.
Discard the exported gallery.
Second option, download the offending page via FTP, edit it and replace on your site.

How can we create a Collective search help

Hi all sap experts,
How can we create a Collective search help on field OBJECT which allows to search tables
o ARCH_OBJ
o TOJTB (Search help: H_TOJTB)
on 2 tabs.
Thanks,
Basu

Hi
1) Elementary search helps describe a search path. The elementary search help must define where the data of the hit list should be read from (selection method), how the exchange of values between the screen template and selection method is implemented (interface of the search help) and how the online input help should be defined (online behavior of the search help).
2) Collective search helps combine several elementary search helps. A collective search help thus can offer several alternative search paths.
3)An elementary search help defines the standard flow of an input help.
4) A collective search help combines several elementary search helps. The user can thus choose one of several alternative search paths with a collective search help.
5)A collective search help comprises several elementary search helps. It combines all the search paths that are meaningful for a field.
6)Both elementary search helps and other search helps can be included in a collective search help. If other collective search helps are contained in a collective search help, they are expanded to the level of the elementary search helps when the input help is called.
CREATION:
Go to SE11 Tcode
select search help
give the 'z' search help name and create
select the selection method ur table name eg : 'mara'
dialog module 'display value immediately'.
add the field whatever u want and lpos = 1 and spos = 1 and check import and export parameter.
where left position when displaying and spos = search position
and then save and activate ..
