OpenBase / boolean / ERPrototypes
Hi All,There seems to be something wrong with booleans when using OpenBase and ERPrototypes.In OpenBaseManager the column type for my column says boolean:In openisql (command line) I can query like this:select count(*) from cliente where suspendido = trueof like this:select count(*) from cliente where suspendido = 1In entity modeler, if I configure my attribute using the boolean prototype from ERPrototypes as shown below, then the queries don't return the right number of rows. The update statements generated by EOF don't work either (even though they look right). If I model my attribute as an integer then the queries work okay and the update statements issued by EOF work too. By I don't like having an Integer in my accessor methods in my EO for a boolean column. I want to use boolean.Looking at the screenshot below, does this look like the boolean prototype is setting the fields correctly for a boolean column in OpenBase? Anybody wants to guess? Anybody using booleans in OpenBase and ERPrototypes? ___ Do not post admin requests to the list. They will be ignored.

Re: ERXEC EOEditingContext in background thread
It locked up again, but I have another clue. Frontbase is outputting
the following error message every 10 seconds.

Also, the current state of the thread in top:

Re: Reference Lib JARs Not Recognized
David, This does help. I actually, normally, do it this way, but at one point in the past I was discussing having the right frameworks on the production servers (keep in mind, I'm small time compared to most people on this list) and someone suggested that for the less-used JARs, I add them to the project so they get moved as part of the project. Am I misunderstanding that? Or, is it generally considered better form to just keep the frameworks all current on production machines (even for the rarely used ones)?

[OT] Generic search component UI
Hi all, I am thinking of implementing a generic search component on top of JBND's qualification system. However, I am having trouble visualizing a really good, user friendly interface for such a component. The main problem: AND and OR qualifiers. I am looking for good ways to handle their creation, manipulation, and display. This is intended for end users defining complex searches, so I need it both easy to use and powerful and flexible. So, if anyone has a pointer to some app that does a good job of handling those, please let me know. Thanks, F ___ Do not post admin requests to the list. They will be ignored.

Re: Digging up a Session object from an EOGenericRecord
We use it without problems since 2 years
But we neither use D2W nor Wonder (except for Ajax) nor nested
context (as far as I know).
We only use adaptated Chuck's ValidatingEditingContext and
EOStateTransition that rocks.

Ok... as suggested by Jérémy I injected my own editing context
using wonder's factory.
I now have a nice place to store my session object directly into
the context.
Question 1: Can you foresee any problems in my editing context
holding a reference to the session? Could it cause garbage
collection delays or stuff like that?
... let's go on I have another question coming :)
Now I placed all this in my code and I still don't get the desired
result. That's because my objects are being fumbled by Wonder D2W
pages. And as I find out, at the time of pressing the "edit" or
"inspect" button, wonder makes his own context and pulls a local
instance of the edited object in it.
So hey... if the guys wrote it like that there must be a good
reason. The following comment from Anjo made me laugh:
//CHECKME ak: I don't remember why we would use a local instance
when we just want to inspect...
Anyway... skipping over the Inspect stuff, when it comes to the
Edit, scrolling through the code I found that there was a binding I
could stick in my rules file to force wonder to at least nest his
new context into mine. So I added "useNestedEditingContext" and
"useExistingEditingContext" in my rules and changed my code to
climb the hierarchy of the parentObjectStore() and it now works.
Question 2: What are the implications of having turned on the
nested contexts? Am I going to face some weird undetectable issue
in the near future that will make me regret this choice?
thx,

Hi,
We do superclass the EOEditingContext according to Chuck's method

When créating the "new" editing context, we pass our Session.
So it's easy to get the session from a enterprise object :
this.editingContext().getSession().
public Session() {
super();
setDefaultEditingContext(new ValidatingEditingContext(this));
}

Re: Digging up a Session object from an EOGenericRecord
Ok... as suggested by Jérémy I injected my own editing context using
wonder's factory.
I now have a nice place to store my session object directly into the
context.
Question 1: Can you foresee any problems in my editing context holding
a reference to the session? Could it cause garbage collection delays
or stuff like that?
... let's go on I have another question coming :)
Now I placed all this in my code and I still don't get the desired
result. That's because my objects are being fumbled by Wonder D2W
pages. And as I find out, at the time of pressing the "edit" or
"inspect" button, wonder makes his own context and pulls a local
instance of the edited object in it.
So hey... if the guys wrote it like that there must be a good reason.
The following comment from Anjo made me laugh:
//CHECKME ak: I don't remember why we would use a local instance
when we just want to inspect...
Anyway... skipping over the Inspect stuff, when it comes to the Edit,
scrolling through the code I found that there was a binding I could
stick in my rules file to force wonder to at least nest his new
context into mine. So I added "useNestedEditingContext" and
"useExistingEditingContext" in my rules and changed my code to climb
the hierarchy of the parentObjectStore() and it now works.
Question 2: What are the implications of having turned on the nested
contexts? Am I going to face some weird undetectable issue in the near
future that will make me regret this choice?
thx,
rdm

But the value is only stored for inspection. Nothing depends on it and it's only to satisfy my client that want's to know who wrote/modified what (it's an online newspaper). In other words it is perfectly fine for it to be empty if I ever used it from outside of my webapp. If it where only for the timestamp I could rely on specific db features like MySQL's ability to auto set the timestamp. But I need the user as well. How does ERXThreadStorage work? What can I assume to be in the same thread? rdm ___ Do not post admin requests to the list. They will be ignored.

Re: Digging up a Session object from an EOGenericRecord
Hi,
We do superclass the EOEditingContext according to Chuck's method
with his ValidatingEditingContext.
When créating the "new" editing context, we pass our Session.
So it's easy to get the session from a enterprise object :
this.editingContext().getSession().
public Session()
{
super();
setDefaultEditingContext(new ValidatingEditingContext(this));
}

Hi folks,
I've encountered this issue (or similar ones) very often now and
I'd love to know how others tackle the problem.
I have implemented a standard way of adding a special timestamp to
all my records in my TGenericRecord (subclass of EOGenericRecord,
superclass of all my eo). The timestamp holds information on when a
record was last modified as well as who did it.
To do this I need to query my session for something like a
"currentUser" method inside the validateTimestamp method of my eo...
Is there a way to climb up to the Session from an EO?
One possible (failed) attempt:
One first clumsy attempt of mine was to override
defaultEditingContext() in my Session object and setting the ec
delegate object to the session itself before returning it. Then
from the eo I would ask for the ec.delegate() and get the session
back.
Should work in theory, even though I dislike the fact that I use
the delegate() that's meant for other things. In practice it
doesn't...
When I factor in my D2W pages my eo don't have the same ec I passed
in at factory creation time and so there's no session there.
Am I blind? Is there a fast an easy way to do it?
