I moved the application from Apex 4.2.6 to 5.1.3 (4). Synchronous execution "dynamic action" is not executed. I'm trying to solve the problem. If I send the item page "File Browse" (P11_FB_ATTACHMENT) through
apex.server.process ("P11_PRC_AJ_FL",
{
pageItems: "#P11_FB_ATTACHMENT"
} ...
then the file is loaded into the BLOB_CONTENT FLOWS_FILES.WWV_FLOW_FILE_OBJECTS$ field, but later I can not normally access it from the PLSQL of the block through the APEX_APPLICATION_TEMP_FILES view using NAME = :P11_FB_ATTACHMENT, because in this case FLOWS_FILES.WWV_FLOW_FILE_OBJECTS$ no data is entered in the fields SESSION_ID, UPDATED_BY, etc. And it seems that the parameter NAME is not transferred back in session to the P11_FB_ATTACHMENT.
From the process P11_PRC_AJ_FL subsequent requests of the form
select *
from APEX_APPLICATION_TEMP_FILES
NAME= :P11_FB_ATTCHANGE
do not work, because apparently there is no session mapping and NAME, in contrast to the "submit".
And now there are no options for uploading files without submit, without creating your own version?
