vladimirpetrov opened a new issue #150: JS errors when trying to sort a column in a grid with missing data URL: https://github.com/apache/cloudstack-primate/issues/150 **Describe the bug** If you try to sort by column and there is a missing element (IP or CPU usage, if the VM is stopped) in the grid, the following JS exception is thrown: vue.runtime.esm.js?2b0e:619 [Vue warn]: Error in v-on handler: "TypeError: Cannot read property 'localeCompare' of undefined" vue.runtime.esm.js?2b0e:1888 TypeError: Cannot read property 'localeCompare' of undefined at stringComparator (sort.js?dbd1:26) at genericCompare (sort.js?dbd1:101) at Object.sorter (AutogenView.vue?feaa:402) at eval (Table.js?372e:346) at Array.sort (<anonymous>) at VueComponent.recursiveSort (Table.js?372e:1011) at VueComponent.getLocalData (Table.js?372e:1029) at VueComponent.prepareParamsArguments (Table.js?372e:958) at VueComponent.toggleSortOrder (Table.js?372e:390) at colProps.on.click (Table.js?372e:855) **To Reproduce** Steps to reproduce the behavior: 1. Go to a grid with missing data in some rows - for example Compute > Instances. If needed - stop some of the VMs. 2. Sort by a column with some missing data - IP or CPU usage, if the VM is stopped. 3. Look at the JS console **Expected behavior** This event (missing grid data) must be handled properly and not throw exceptions. **Screenshots** Not needed. **Desktop (please complete the following information):** - OS: Windows 10 Pro x64 (doesn't matter) - Browser: Chrome - Version 79.0.3945.130 (Official Build) (64-bit) **Additional context** Sometimes it leads to some strange UI behavior as well.
