SV: Call managed bean method based on request attribute

[hermod.opstvedt]

Hi   Another solution to this is to do something like this:    <managed-bean>         <managed-bean-name>customer</managed-bean-name>         <managed-bean-class>xx.xx.xx.Customer</managed-bean-class>         <managed-bean-scope>request</managed-bean-scope>   <managed-property>    <property-name>custId</property-name>    <value>#{param.id}</value>   </managed-property> </managed-bean>   When your bean is being construted, the request parameter (#{param.id} will be inserted into it.     Hermod -----Opprinnelig melding----- Fra: Frode Oldervoll [mailto:[EMAIL PROTECTED] Sendt: 2. november 2005 08:08 Til: 'MyFaces Discussion' Emne: RE: Call managed bean method based on request attribute Use FacesContext.getCurrentInstance().addMessage   -Frode   From: Robert Parsons [mailto:[EMAIL PROTECTED] Sent: 2. november 2005 07:37 To: MyFaces Discussion Subject: Re: Call managed bean method based on request attribute   Thanks! Just another question if anyone is still around, if I want to add a message to the response from a bean method rather than at validation time (such as 'save' method), how do that? The only way I can see of adding messages is by throwing a ValitatorException :S. Thanks in advance, -Robert.

If I have a managed bean that represents some database entity, how can I populate that bean from the database based on a request parameter?   For example, say I have a managed bean called Customer. The form for editing the bean is 'editCustomer.faces'. If the page is accessed directly (without any request parameters) a blank form is dispalyed which can be used to create a new Person. (which would possibly have an action for inserting it into the database).   However, if a request like 'editCustomer.faces?id=14' was issued, I want the Customer bean to load customer number 14 from the database.   What is the best way of achieving this with JavaServer faces? This whole managed mean is making my old methods of working a little difficult.   Thanks in advance, Robert.           -- Mathias         * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * This email with attachments is solely for the use of the individual or entity to whom it is addressed.
