Refresh a view after an action

[Former Member]

hi,

I made a view with both a table and a form, i use the form to fill the table besides but i got a problem the table is not refreshing after clicking to the action button.

Is there a way to make a refresh ?

Regards,

FM

You don't need to refresh explicitely. Can you post your code?

Frantz,

And what action is not working? Plz provide action handler name.

[Former Member · Accepted solution]

onActionAjouteruncandidat is the action where the refresh on the table is not made

Frantz,

Am I correct whith the following guess: Table dataSource is node nodeRequest_ATR2ViDocument_getAllCand or table cell editors is bound to this node, but form controls use node nodeRequest_ATR2ViDocument_saveCand instead? So, table cell editors and form controls bound to different attributes?

If so, then no automatic "synchronization" possible, you have to copy values manually (in action handler) between node elements.
