Display a table by clicking on a form button



I want to display a table which needs to be filled with a variable containing a response of a REST service. I need this to be shown after clicking on a form button. Any guidance on how can I achieve this?

Thank you!!


Hi Romina,

what kind of Form are you currently using?

I suggest you take a look at embedded forms if you haven’t already.

Best Regards


I’m using embedded forms. I define it on an html file. I want the user to fill certain fields and after clicking a button, I want to display a table.

In this table I want to fill it cells based on a response which i want to obtain after clicking that button.

Now, i realize i have a major question. Can I define that after clicking that button, certain function is executed? From this execution (which is a REST service) is from where I will obtain the info to fill the table cells.


Yes, this is possible. You can execute custom JavaScript in embedded forms. See the example here: https://github.com/camunda/camunda-bpm-examples/blob/master/usertask/task-form-embedded/src/main/webapp/start-form.html#L72-L106


But without executing custom JavaScript in my embedded form, can I associate the button to some class and in that class call the REST service and with the response fill the table on my form?

Thank you!



What kind of class are we talking about? It is not possible to attach a Java Class to a Form field.

To me, custom JavaScript seems like the obvious solution. Simply add an ‘onclick’ event to the button and make a REST call. Please explain in more detail what you are trying to achieve and why you can’t use JavaScript


I thought the best way was to use a controller but i was not having any success :pensive:
So, I should include a custom JavaScript on my form? And on the “onclick” event I put a function of my script?


Yes, simply add a script tag in you html and add the function you define inside to your buttons onclick event
