Lego team "==== What steps will reproduce the problem? 1. Add a tag on way with more than 255 characters on a server that allows > 255 maxlength. 2. Click upload changes 3. ==== What is the expected result? Have the server throw an error (if public OSM), work fine on a private OSM if > 255 characters allowed. ==== What happens instead? Throws an error saying tag value too long. ==== Please provide any additional information below. Attach a screenshot if possible. I have a private server that allows more than 255 characters on nodes and ways. 19437 has added length checking client side with no way to switch it off or change the maxlength allowed. I was wondering if an option to switch off client side tag length checking in advanced settings please? The change tag length change was also not in the changelog. {{{ Revision:19437 Build-Date:2025-08-26 Identification: JOSM/1.5 (19437 en_GB) Windows 11 64-Bit OS Build number: Windows 10 Pro 24H2 (26100) Memory Usage: 352 MB / 11832 MB (52 MB allocated, but free) Java version: 21.0.8+9-LTS, Azul Systems, Inc., OpenJDK 64-Bit Server VM Look and Feel: com.sun.java.swing.plaf.windows.WindowsLookAndFeel Screen: \Display0 1920x1080x32bpp@60Hz (scaling 1.25×1.25) Maximum Screen Size: 1920×1080 Best cursor sizes: 16×16→32×32, 32×32→32×32 System property file.encoding: UTF-8 System property sun.jnu.encoding: Cp1252 Locale info: en_GB Numbers with default locale: 1234567890 -> 1234567890 VM arguments: [-Djpackage.app-version=1.5.19439, -XX:MaxRAMPercentage=75.0, --add-modules=java.scripting,java.sql,javafx.controls,javafx.media,javafx.swing,javafx.web, --add-exports=java.base/sun.security.action=ALL-UNNAMED, --add-exports=java.desktop/com.sun.imageio.plugins.jpeg=ALL-UNNAMED, --add-exports=java.desktop/com.sun.imageio.spi=ALL-UNNAMED, --add-opens=java.base/java.lang=ALL-UNNAMED, --add-opens=java.base/java.nio=ALL-UNNAMED, --add-opens=java.base/jdk.internal.loader=ALL-UNNAMED, --add-opens=java.base/jdk.internal.ref=ALL-UNNAMED, --add-opens=java.desktop/javax.imageio.spi=ALL-UNNAMED, --add-opens=java.desktop/javax.swing.text.html=ALL-UNNAMED, --add-opens=java.prefs/java.util.prefs=ALL-UNNAMED, -Djpackage.app-path=%UserProfile%\AppData\Local\JOSM\JOSM.exe] Dataset consistency test: No problems found Last errors/warnings: - 00000.733 W: extended font config - overriding 'filename.Malgun_Gothic=malgun.ttf' with 'MALGUN.TTF' - 00000.736 W: extended font config - overriding 'filename.Myanmar_Text=mmrtext.ttf' with 'MMRTEXT.TTF' - 00000.737 W: extended font config - overriding 'filename.Mongolian_Baiti=monbaiti.ttf' with 'MONBAITI.TTF' - 00001.602 E: java.security.KeyStoreException: Windows-ROOT not found.
