Change component "rendered" property from button ActionEvent

Oracle Jdeveloper 11g Release 2.

Hi.

I need by using the button to change the property "rendered" in two forms on the page.

When you start the application was active RO form, after clicking on the "Edit form" button, the form was replaced by a EDIT form (RO form - rendered = false, and EDIT form - rendered = true).

And after we push the button "commit", the form is again read (RO form - rendered = true, and EDIT form - rendered = false).

Your requirement is not clear but the thumbrule while using render = true / false is trigger the parent component because once render=false,  you cannot make render=true by trigerring same component. Its possible with visible attribute only.

Use visible instead of render

Read difference in both - ADF Rendered vs Visible

Hi Celeboncho

i like to use " display:none; " in the InlineStyle maybe this solves your problem.

Thank you. But how can i do it with visible property? how to change the properties value from java class?

Suppose you have a field on page then take a Boolean variable in managed bean and it's default value is true (means it is visible). Now associate this bean variable to visible property of field like this

#{pageFlowScope.ManagedBeanName.varName}

and then on any button click you can change it's value to false

You have to maintain a boolean flag in manage bean (java class) and map that variable to component's visible property. Based on your logic make that flag = true/false and trigger the component or its parent. That will work.
