reproduction example

+++ This bug was initially created as a clone of Bug #88092 +++

Reproduction instructions:

1. Open attached document, allowing macros to run.

2. Click "Set Struct" button. Click "OK" on the message boxes appearing.

3. Click "Set Show Struct" button.

Actual behaviour:

  In execution of doShow from the button event (that is, after doSet has
  finished executing), aStr keeps the value assigned to it by doSet,
  but aDate is reset to default (all zeros) value.

Expected behaviour:

  Since aDate is a global, it should keep the value that was assigned
  to it by doSet.

The same can be observed by going in the Basic IDE and running (F5 or the toolbar button) the macros from there.

Repro on Win & Linux.

Changed component to BASIC, I hope it's ok.

Comment 5 John 2021-03-03 16:05:59 UTC
It's worth noting that this is an issue with the "as new" construct. Changing the example macro to use:

Global aDate        as Object

and in doSet

Set aDate = new "com.sun.star.util.Date"

before setting the values and for safety, 

	if not isNULL(aDate) THEN

in doShow


And now aDate can hold its value. There's something about the "as new" construct that causes it to get re-initialized to a new object when run the next time.I'm not certain, but I believe this to be incorrect behavior.
