Can't change button href dynamically in primefaces

Question

I am trying to access to a controller when clicking on a button. The fact is, i need to change the url of the button dynamically.

<p:button styleClass="btn-openHtml" href="#{data.htmlRenderUrl}" value="button html" target="_blank"></p:button>

The href property isn't updated when my bean's property changes. How can i make it so the value of href is updated when data.htmlRenderUrl is changed?

You should use ajax process and update attributes to clearly indicate when and what should be updated as the result of an event. — Onur Baştürk, Dec 21 '21 at 13:47

you have to update the button with ajax. when you update the property in your bean:

...
htmlRenderUrl = "/home";
//update your button
PrimeFaces.current().ajax().update("button-id");
...
