Hi,

I'm trying to set the values of an enity bean of which one value has to be 
chosen/set from a different page. The user gets to the page by clicking on a 
link whose link text displays the current value. The link is contained inside 
the same form, which contains the other input fields and the save button to 
persist the entiy.

The problem I ran into is that all the other values get validated, when the 
user clicks on the link. The result is that the current page is redisplayed 
with error messages showing on the invalid input fields.

Instead, I would like the user to be able to fill out the form of which some 
values are constrained (ie have to be valid). Then the user may click on the 
link to setup this special value, without his current input being validated and 
thereby lost, even if it's partly invalid.

After picking the special value from the other page he gets sent back to page 
from which he came and should see (as mentioned above) all the other values of 
which some may be invalid.

The page should only be redisplayed, if the user entered invalid input AND 
clicks on the Save button to persist the entity. Otherwise he should be 
forwarded to the page to set the special value an the current input should be 
displayed, after he is done.

I tried to set immediate="true" on the the link, which one has to click to 
setup this one special value. If I do so, then the user can proceed to the 
other page, but all the values which the user had entered previously are lost, 
when the original page is redisplayed.

I haven't figured out how to do this. Is it possible at all?
