Update Entry: Call of OnSysvar_Update from a Panel

Last updated: 2018-09-21
Issue:
Update Entry: Call of OnSysvar_Update from a Panel
Background:

When setting the value of a System Variable on a Panel without changing the value, the CAPL event OnSysvar_Update is NOT called. Only value changes of System Variables on Panels will call a CAPL event: with every value change OnSysvar and OnSysvar_Update are called.

Solution:

When using the predefined Symbol Panel, the sending of a System Variable value can be forced. In this case, the CAPL event OnSysvar_Update is called when the same value for a System Variable is sent again, and OnSysvar is called when a changed value for a System Variable is sent.
