Description Ewald Anderl 2014-05-05 22:52:35 UTC
Problem description: 

When a Print statement is used in an “On Error GoTo” catch routine, the information in Err, Erl, and Error is not reliable in some cases; for example, this can be reproduced when errors are generated by the Simple File Access object's getFolderContents() method. The Print statement appears to display error information from prior errors not the current error. This occurs in both Linux and Windows environments. It is not clear if this is limited solely to an interaction with the Print statement or if there are other ways in which this bug can surface. It is not clear why the Print statement behaves in this manner and does not print all of the information associated with the current error.

Steps to reproduce:

This is reproducible by catching errors from the “getFolderContents()” method. This appears to generate two additional errors internal to LibreOffice for a total of three errors to be printed. Only two are printed. After the first such error, the Catch routine falls further and further behind, which is very confusing for any attempts at understanding or debugging (see 3.1, “Results with Debug Level > Zero“ for more information).

Current behavior: Incorrect information is displayed for Error, Erl, and Err.

This also leads to unexpected output at the end of the program execution (see Illustration 2: Unexpected output at the end of program execution and  Table 5: Result summary for Linux, getFolderContents() method for more information)

Expected behavior:

Caught errors should generate all output conurrent with the error event.

I will upload a separate document with screen shots and supporting documentation.

This has been unconfirmed for 2,5 years, because there is no test document to easily reproduce the issue.
Please attach such a document, your steps to repro are not clear enough. Testers should not have to think. You should view us as trained monkeys.
