Re: PrimaryKey generation takes a lot of time
Hi all, First i've tryed to set the size of primaryKeys fetched per statement in _FrontBasePlugin to 500. I've gained abound 5%. Next i've tryed to use ERXJDBCAdopter with batchsize 1000, but got no benefit. Then I tryed connectionpooling, but ended with a lot of exceptions, because the initialisation of Connections got broken. I switched to ObjectStoreCoordinator and the performance got worse. Multithreading did also slow down the application (With 2 Threads i got a better performance by about 3-5%, but with more threads the performance slows down by 5% with 10 Threads and 15% with 20 Threads). My solution: 1. Return the hole multithreading, ObjectStoreCoordinator. 2. Configure Testinstance on Productionsystem only to import the data. Database near Applikation got me to speed up. the 5 hours import is done in 5min. Its not the best for me, but with the latency and slow connection issues it's the best i can get. Thanks for all your hints. regards Tobias 2014-05-06 10:40 GMT+02:00 Patrick Middleton patr...@onestep.co.uk: We encountered this recently against MySQL 5.6.12. (Not using Project Wonder) The default primary key generation was invoking a stored procedure once per row. Once per second, some sort of garbage collection would occur inside the RDBMS and the stored procedure would take about 0.2s to complete instead of about 0.005s. The fix is to create and cache all your new primary keys at once in advance using something like er.extensions.jdbc.ERXJDBCAdaptor.Channel.primaryKeysForNewRowsWithEntity(int cnt, com.webobjects.eoaccess.EOEntity entity) then use something like databaseContextNewPrimaryKey(EODatabaseContext dbCtxt, Object object, EOEntity entity) http://wocommunity.org/documents/javadoc/WebObjects/ 5.4.2/com/webobjects/eoaccess/EODatabaseContext.Delegate. html?is-external=true to fetch a candidate new key from your cache rather than make a database round-trip to make one.

You can’t directly, AjaxGrid does that.
I think what you want is to have a link or button in each row that does
something when activated. Otherwise you are trying to bend AjaxGrid to do
something it was not intended for. Neither you nor your users are likely to be
happy.
First you need a grid configuration like this:
*{
*title = quot;Actionsquot;;
*keyPath = quot;quot;; // Missing or
empty keypath results in the current object itself being passed to component
*component = quot;EmployeeActionsquot;; // Name of
WOComponent to be displayed in this column. Gets passed two bindings: value
(Object),
* // and grid
(AjaxGrid) so that any other needed data can be accessed
*cssClass = quot;alignCenterquot;;
*}
Then in the component some simple HTML like:
span style=float:middleWEBOBJECT NAME=Remove//span
Then use a regular link or an Ajax one, depending on what you want to happen:
Remove: WOHyperlink {
action = remove;
string = Remove;
}
And implement the action method to do what you want.

Re: AjaxGrid single row select UPDATE
Jens:
I’ve implement a SingleSelectionAjaxGrid that extends AjaxGrid. Actually, it’s
twice removed. :-) Anyway, I don’t think there’s any major changes in the
parent class. There’s a class variable for selectedObject and the following
override below ’toggleSelectionOfRow.’ The component has a api binding for
selectedObject.
/**
* Toggles inclusion of row into selectedObjects() (i.e. selects and
* de-selects it). This component can only have one selected row.
*/
public WOActionResults toggleSelectionOfRow() {
//row was already selected
boolean _rowWasPreviouslySelected = (selectedObjects() != null
selectedObjects().contains(row()));
selectedObjects().removeAllObjects();
if (! _rowWasPreviouslySelected) {
setSelectedObject(row());
selectedObjects().addObject(row());
} else {
setSelectedObject(null);
}
return null;
}
Also, in the wod, the tr for the row repetition has been updated as below. This
allows you to click anywhere in the tr to select.
TableRowAndToggler: AjaxUpdateLink {
action = toggleSelectionOfRow;
updateContainerID = configurationData.updateContainerID; // VALID
id = toggleRowSelectionID;
elementName = tr;
class = rowClass;
style = rowStyle;
}
Hopefully, this helps you out.

permanentGlobalID not permanent
PrimaryKey obtained by permanentGlobalID() are not saved as the primaryKey on
saveChanges().
I'm setting a global id as a reference for « soft relationship » (since it
point to undefined object) instead of a « hard relationship » (usual when we
store the pk).
The problem is that I get 2 primary key (yes 2 sequences number out of the
database):
- the first come from the call to permanentGlobalID(), wich return 7985.
- the next come from the save of the object itself, it ask again for a sequence.
Result: the first reference is actually not pointing to the saved object!
Here is the code for the setter:
public void setReference(final ERXGenericRecord ref) {
EOKeyGlobalID pgid = ref.permanentGlobalID();
setReferenceGlobalID(ERXKeyGlobalID.globalIDForGID(pgid));
// added log to debug ...
final EOGlobalID gid = editingContext().globalIDForObject(ref);
log.debug(GlobalID: + gid + permanent: + pgid);
}
give:
GlobalID: EOTemporaryGlobalID: 0 0 127 0 0 1 0 0 -5 -116 1 0 0 0 1 69 -39 18
-94 -76 -125 18 82 -3permanent: _EOIntegralKeyGlobalID[AGA_Participant
(java.lang.Integer)7985]
It's a wonder project, all EOs (ultimately) inherit from ERXGenericRecord.
I'm using ERXEC default factory to get editingContext.
From the documentation it says it is supposed to work, so I guess I have
something misconfigured.
But from debuging the code it doesn't look at all like it's supossed to work!
When deep inside the saveChanges(), it simply call toBeSavedEO.__globalID()
which still return the temporaryGlobalID instead of the permanent one.
To illustrate here is a patch that make it work:

public WOActionResults toggleSelectionOfRow() {
//row was already selected
boolean _rowWasPreviouslySelected = (selectedObjects() != null
selectedObjects().contains(row()));
selectedObjects().removeAllObjects();
if (! _rowWasPreviouslySelected) {
setSelectedObject(row());
selectedObjects().addObject(row());
} else {
setSelectedObject(null);
}
return null;
}
Also, in the wod, the tr for the row repetition has been updated as below.
This allows you to click anywhere in the tr to select.
TableRowAndToggler: AjaxUpdateLink {
action = toggleSelectionOfRow;
updateContainerID = configurationData.updateContainerID; // VALID
id = toggleRowSelectionID;
elementName = tr;
class = rowClass;
style = rowStyle;
}
Hopefully, this helps you out.

Hi Jens,

Hello,
for my AjaxGrid I have two questions. (I'm not very familiar with JavaScript)
How to define a single row selection? (At the moment I can select and
deselect multiple rows).
You mean that you want to prevent the user from selecting more than one row?
It does not support that. You probably could in JavaScript, but this is
probably the wrong UI for what you are doing.
How can I react on the selection and deselection event in my Java Class? The
setSelectedObjects method is not called.
You can’t directly, AjaxGrid does that.
I think what you want is to have a link or button in each row that does
something when activated. Otherwise you are trying to bend AjaxGrid to do
something it was not intended for. Neither you nor your users are likely to
be happy.
First you need a grid configuration like this:
*{
*title = quot;Actionsquot;;
*keyPath = quot;quot;; // Missing
or empty keypath results in the current object itself being passed to
component
*component = quot;EmployeeActionsquot;; // Name of
WOComponent to be displayed in this column. Gets passed two bindings: value
(Object),
* // and grid
(AjaxGrid) so that any other needed data can be accessed
*cssClass = quot;alignCenterquot;;
*}
Then in the component some simple HTML like:
span style=float:middleWEBOBJECT NAME=Remove//span
Then use a regular link or an Ajax one, depending on what you want to happen:
Remove: WOHyperlink {
action = remove;
string = Remove;
}
And implement the action method to do what you want.
Chuck
I can't find a description / example in the web.
Thanks
Jens
UPDATE: I found a solution in checking the change of selectedObjects in
public WODisplayGroup displayGroup()
I don't know if that is a good solution but it works.
