Comment on Ajaxifying a Grails Webflow by duh

Jie, if your load balancer is configured to direct user sessions to the same server it should not be a problem. However if your load balancer is configured to balance on every requests (so individual requests end up on different servers) you should probably set up tomcat session clustering as well. But then you would probably run into issues with the file uploads themselves as they are being stored locally (a second onSuccess request might be directed to another server where the file does not exist). So it would probably best practice to set up your load balancer to keep user sessions on the same server.

Can I manage the flow-state on the client side instead of session? For load balancing server applications.

Hi Eduardo,

Instead, try: Category.findById(params.id)

Cheers, Jeroen

I’ve got the following error while running my code with this example

in this line :
def category = Category.get(params.id)

Ik heb er nog geen nee. € 1200,- is ook wel een beetje aan de prijs, maar goed: blijft een mooie lamp

Heb je misschien al een kleinere versie gevonden? Ik ben er ook naar op zoek.

Hi Eric,

Sorry for not noticing your posts sooner than just now. Unfortunately my cable provider blocks smtp, so my blog is unable to send out notification emails when someone posts comments Perhaps I should move the blog out of my meter box onto an external server

But I see you already found the solution to your question? So, if I understand correctly you are using a flow to edit the properties of one particular domain object?

It’s indeed possible to add the id to the hidden field in the form specification, however as this id is being used throughout the whole web flow / wizard, I would probably store it in the flow scope instead of passing it along every time in a hidden post variable.

The flow scope is available throughout the lifetime of the web flow. So I would probably either store the id in the flowscope, or instantiate the domain object by id and store that in the flowscope so you can use and modify that object throughout the web flow.

I hope this answer is of help? Let me know if you got things working

Cheers, Jeroen
