Issues Fixed in LabVIEW 2019 f1 Patch

ID Description
647006 In extremely rare cases, LabVIEW freezes while building an application that contains classes within packed project libraries.
734726 VIs in source distributions created by NI Package Builder may show up as broken in TestStand.
736066 In rare cases, using multiple CPU cores to mass compile large projects that contain LLBs in auto-populating folders crashes LabVIEW.
736429 If the data type of a set or map is a class, the set or map will incorrectly break when an instance of a child class is added.
737362 Using a Waveform datatype as a key of a map or member of a set can corrupt the VI.
738357 The Build Map and Build Set functions incorrectly show a broken wire when you input sibling classes to these functions.
738428 When indexing over a map with array values, the indexed array value may appear empty.
738483 Wiring the default value from the Look In Map function to the connector pane can cause LabVIEW to hang.
738644 Error Case structures incorrectly rename no error case to "Error 1" if INI token funkyerrclustWire is set to True.
739017 In rare cases, malleable VIs inside of classes will fail to load correctly when called from TestStand.
739174 When an Error Cluster Constant is wired to a Case structure that only handles Error 1, the Case structure incorrectly handles all errors in this case.
739207 In Place Element Structures incorrectly output a string for all map key values independent of the value's data type.
739357 When using VI Scripting to simultaneously load XControls and close their containing projects, LabVIEW can crash.
Note: In order to apply the change for CARs 738428 and 739207, you need to recompile affected code.
This can be accomplished by force recompiling the affected VI hierarchy: <Ctrl+Shift> + Run Button.
