Cannot read property 'getSelection' of null, when clicked to close or cancel button about html-integrations HOT 2 CLOSED

Hi @doox911, thank you for contacting us.

The problem is that, with the code you are using to integrate the Wiris Generic plugin, you are not defining an important element (also necessary for other MathType functionalities) called currentInstance.

Here is what you can do to integrate the plugin with the currentInstance object, so you'll have the cancel and close buttons working again:

• Use the window wiris function to initialize the Generic integration:

  window.wrs_int_init(taget, toolbar)
  

  instead of this part of your code below:

  this.wiris_generic = new WirisPlugin.GenericIntegration(genericIntegrationProperties);
  
  this.wiris_generic.init();
  this.wiris_generic.listeners.fire('onTargetReady', {});
  

  Our function contains the same code you are using, with some other definitions necessary to build the currentInstance object.

• Import the wrsInitEditor function from '/node_modules/@wiris/mathtype-generic/wirisplugin-generic.js', and use it to initialize the editor: wrsInitEditor(target, toolbar), same behaviour as the previous point, you have to use our function instead of your last 3 lines of code.

• Manually, create a definition of the current instance: following your code, will be something like this:
  WirisPlugin.currentInstance = this.wiris_generic;. In this case, you can add this line to your code. My recomentadtion would be after the fire of 'onTargetReady' listener.

• In the worst of the cases, you can downgrade your mathtype-generic plugin to the version 7.26.1.

The first 3 options, are all great to solve your problem, none of them is better than the other, so choose the one you find more interesting.

If you have more issues, please feel free to contact us again.

WirisPlugin.currentInstance = this.wiris_generic; - works.

Thank you very match!
