When we want to reassign client with a rescheduled loans to a different group, there is the following error:
exception.accounts.changeInLoanMeeting=Cannot create a loan as frequency of loan product has already been modified by another user.
but this error is not displayed on the page.
I fixed it by adding a proper message to the ClientUIResources.properties, but it seems that this exception is no longer thrown in the 2.2.x release.
I decided to not commit this fix to the repository. If someone encounters the similar problem in the future, we will fix it then.
