This has been resolved internally and the fix will be present in the 7.0 final release. In the meantime, here's a patch for the 7.0 RC2 build
Code:
//---------------------------------------------------------------------------- // Isomorphic SmartClient 7.0rc2 patch // Purpose: Fix for an error screenReader and Calendar components. // // Applies to SmartClient 7.0RC2 builds only //---------------------------------------------------------------------------- if (window.isc && isc.version.startsWith('7.0rc2')) { if (isc.ListGrid) { isc.ListGrid.addMethods({ getRowWAIState : function (rowNum) { var record = this.getRecord(rowNum); if (this.selection && this.selection.isSelected && this.selection.isSelected(rowNum)) { return {selected : true }; } } }); } } else if (window.isc) { isc.Log.logWarn("Patch for SmartClient 7.0 Release Candidate 2 included in this application. " + "You are currently running SmartClient verion '"+ isc.version + "'. This patch is not compatible with this build and will have no effect. " + "It should be removed from your application source."); }
