Rules and Pop up "Changed by another user"

astri · Post by **astri** » Mon Nov 09, 2009 7:45 am

Hi,

I have a business object (call it BO) with rules on it. BO has attributes BO.Attr1, BO.Attr2, etc. Those 2 attributes are described in rules related to READ PROTECT another attribute, for example:
IF BO.Attr1='In Progress' THEN READ PROTECT BO.Attr3 FROM ALL
IF BO.Attr2='Critical' THEN READ PROTECT BO.Attr4 FROM ALL

When I test it, I create 1 record of BO. Then I edit the record, change the value of BO.Attr1 and save the record. A pop up then shows "BO has been changed by another user. Please get the latest version of the data and try the operation again."

This doesn't happen when I change and save BO.Attr2 or another attributes.

I continue this application development from someone else. Looking at the error message, I thought that he might referenced the attribute to SystemSettings, but I check it isn't referred.

Do you have any idea about this? Thanks for any suggestion.

Sounds like a bug. Do you have an example that you can send to [email protected]?

This should be fixed in build 1269

When editing an object, I am now getting the 'BO has been changed by another user. Please get the latest version of the data and try the operation again.' error

Here is some output from Tomcat:

Any help would be appreciated.

additional information.

I got the error in the previous post when I made a lot of changes on the screen.

If I make several changes, save, some more changes, save, etc, I do not get the error.

I have narrowed down when I get the 'BO has been changed by another user...' error and I think there is a bug in Aware.

My BO has a reference to another object which is displayed as a drop down. After creating the BO, I do not want this relationship changed, so I have the following rule:
NOT (BO IS NEW)
PROTECT BO.Relationship FROM ALL EXCEPT System.

I create my BO from a menu item which has 'Show object details after creation' ticked.

When I create my BO and hit the 'Create' Button, my BO remains on the screen and I edit it. When I then hit save, I get this error.

If I remove my protect rule or leave the BO and come back to it to edit it, I do not get this error.

Let me know what you think

I can confirm the same problem, when using a PROTECT rule on a BO attribute, after the initial save, when I try to continue editing the forms (unprotected) attributes I get an error '...has been changed by another user...'

When I remove the PROTECT rule, there is no error.

Should be fixed in build 1309
