ORA-00001: unique constraint violated GMSC2.PK_SESSION


I have a form in GeoMedia Smart Client 2016, containing button that should save form data to database.


<FormAction name="Save_form" label="Zapisz" visible="form" type="form" action="save" />  


After pressing this button, application starts to save data, but it can takes even 10 second to complete.(probably it because the form is quite complicated). The problem is, when user click this button again (I mean click it before saving data to database is completed). Then the error apears in workflow log "ORA-00001: unique constraint violated (GMSC2.PK_SESSION)"

What is the simplest way to lock the button after click and unlock it after save is complete? Or maybe there's another better solution?


Below is full stacktrace:

Re: ORA-00001: unique constraint violated GMSC2.PK_SESSION



it looks quite strange to me a so long process to persist the data in the database. Please check if there is any problem with the database setup and/or issues in connectivity from the App Server to the DB.

To solve it on the client side I would use something like this (I did not test the code):


busyDialog = IG.Busy({
    message: 'Saving data'
