when you disable the annotation editor using the following settings:
<ejs-pdfviewer [toolbarSettings]="toolbarSettings" [contextMenuOption]="'None'" [enableBookmark]="false" [enableTextMarkupAnnotation]="false" [serviceUrl]="service"> </ejs-pdfviewer>
toolbarSettings: ToolbarSettingsModel = { toolbarItems: [ 'OpenOption', 'PageNavigationTool', 'MagnificationTool', 'PanTool', 'SelectionTool', 'SearchOption', 'PrintOption', 'DownloadOption', 'UndoRedoTool' ] };
Clicking an form-field works fine the first time but after the second time the following exception occurs:
TypeError: undefined is not an object (evaluating 'this.annotationModule.textMarkupAnnotationModule.selectTextMarkupCurrentPage')
Which appears to be happening here. This exception blocks the signature dialog to open when it has been closed for the first time.
Hovering over the buttons in the toolbar will result in the following exception:
TypeError: undefined is not an object (evaluating 'this.annotationToolbarModule.shapeToolbarElement.contains')
Which appears to be originating from here.
