ID becoming null when trying to save entity.

[cdiggins]

I have been having difficulty getting an entity record to update data. I am using a @Factory menthod to load an @DataModel list, and the selecting a record using @DataModelSelection. Once this data is loaded I can see on the page (outputText) that I have the proper ID from the database. If I then click Save on the page and have a breakpoint on the first line of my save method, I find that the ID of the entity is now null.

If anyone has any idea what could be done to prevent the ID from becoming null, I would appreciate it.

Thanks,

Problem solved.

I at first did not have a field at all to take the ID, reasoning that if there was no field it would keep the previous ID value from the database. This was incorrect; the solution now used is to have an inputHidden bound to the ID property of my entity, which then passes the ID (if there is one) to the save method of the bean.

That's certainly not necessary (take a look at any example).

How are you holding state in the app? In a long running conversation?

It is now a long-running conversation, this being my first seam project and I had not realized that was how to do it. It works without the hidden field - that just happened to be the first solution I found.
