Return error message in plugin to action / JS

Dear all,

I write a plugin to get page values and set some fields, and it is triggered by a custom ribbon button. So I reference the following link https://www.greenbeacon.com/insights/trigger-plugin-from-ribbon-button-using-custom-actions-in-dynamics-crm-2013/ to create an action first and then write some javascript code as it said. And I also register my plugin 'pre-operation' stage.

Its execution order should be Ribbon button > JS > Action > Plug-in

Now there are some custom error messages in my plugin, need to be shown up on the client side (maybe alert)

I tried to add InvalidPluginExecutionException("my error message.") in the plugin but I don't know how to get it in my javascript function.

Or should I add an output parameter in my action? But I notice that if you want to get the output value in your action, you should only register plugin on 'post-operation' stage?

Thank you for your help.

Hello,

First thing - use Output Parameter.

Second - register your plugin to work in Post-Operation stage and populate output parameter in it (population in pre-operation would not work).

Hi Yvonne,

You can add an output parameter to your action with type string and set it to the alert you needed.

Also, the output parameters can be set only in the post operation stage of the plugin.

Hi Andrii,

thanks for your reply.

but it's another point that I have to set values to fields and then do service.update(entity) in my plugin so I register the plugin in pre-operation stage.

If I register it in Post-Operation stage, updating doesn't work.

Hi Nithya,

thanks for your reply.

I have to set values to fields and then do service.update(entity) in my plugin, that's why I register the plugin in pre-operation stage

Is there another way to resolve this?
