I have been working on converting a simple MVC application into Spring Boot Application with ExtJs as front end. Facing issue with ExtJs inside xeditor iframe and Spring boot Rest Api

Error below:

xeditor_core.min.js:formatted:2:8698 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'QuickTips')

xeditor_core.min.js:formatted:2:10701 Uncaught (in promise) TypeError: Cannot read properties of null (reading 'length')

Code :

1] this.iframeDocumentBody.appendChild(this.iframeEditorContentContainer),

2] this.iframeBody.appendChild(this.iframeDocumentBody),

3] this.iframeWin.Ext.QuickTips.init(),

Here the Ext Object at line 3] is NUll , However in the original MVC application this object is present.

4] this.iframeEl = Ext.get(this.editor.iframe),

5] this.iframeWin = this.editor.iframe.contentWindow,

at line 4] the EXt object is present not present in contentWindow object in line 5].

Both the old MVC and the Spring boot Rest Api give the same response .

can anyone help me out.

This could be an issue in your static/iframe.html file. Make sure that the following line is included:

<script type="text/javascript" src="./lib/extjs/all.js"></script>

This will inject ExtJS into the iframe and include the Ext namespace there, so Ext.QuickTips should be available again.

In addition, the Developer Network Panel should be used to ensure that the file can be loaded successfully.
