OutputText only refreshes after Tomcat Restart

I'm using Tomcat 7, Eclipse Juno (in Windows 7) and Primefaces 5 for my application.

After registering some information in the database (vaccines for vaccination book), access a screen (vaccine-caderneta.xhtml) to view the status per patient of my system.

The fact is that when the PrimeFaces dataGrid is loaded, it does not display the information in the same way that it is arranged in the Database (MySQL / JPA-EclipseLink). More specifically, the "dtPrevistaApplication" field.

And the most curious thing is that after a Tomcat 7 RESTART, the values in this field are displayed correctly.

vaccine-caderneta.xhtml

How to handle the requirement for certain attributes in models that include a concern in Rails? How to validate input file with jquery validation?

score 1 · Accepted Answer

I found a solution to the problem.

I identified that in reality the problem only occurred when the dtPrevistaAplicacao attribute of the Vacinacao.java class was being sent to the database with an object of type java.util.Date , while manipulating the data within a ManagedBean. >

So, in the GET method that JSF uses to populate the rendered component of Primefaces on the screen, it repeats the value for all lines of dataTable or dataGrid .

Using objects of type Calendar , which is by far the most recommended, the problem has been solved. Using java.sql.Date is also an option.
