I had a situation once, when i made a reRender on input, on a rich:suggestionbox, so when the reRender was made, the box was showing on the top of the web page, and i couldn’t make any selection. So the problem was because the suggestion box was rerendering itself. I removed the suggestion box from the rerender, and all worked fine.
I had an error, with a4j:support, reRender, when i tried to make a reRender onchange on a suggestion box, or on a combo box. So the thing was that the component i was re rendering had an attribute rendered, which was wrong, because the reRender should be made on a parent of the component which contained the rendered condition, that because the reRender algorithm doesn’t know the component that need’s to be rendered, if it has a rendered attribute. So the explanation is on exadel’s web site live demo:
And from there we find out the following thing:
Therefore, after the component becomes rendered during the Ajax request, RichFaces delivers the rendered code to the client, but does not update a page, because the place for update is unknown. You need to point to one of the parent components that has no ‘rendered’ attribute. As an alternative, you can wrap the component with a4j:outputPanel layout=”none”.
So we shold have the following code (as an example):
si in alta parte:
So the thing should be solved now. Thank God !
1. Flip the wireless switch located at the front of the Dell Vostro, to the left of the speakers and headphone connections, to turn on all wireless connections. If you cannot find a wireless switch, hold down “Fn” and “2” to turn on wireless.
Must try to install the drivers from the following link:
Here they say for the network card, not for the wireless card problem that we may use the following:
- R282234.exe if you have 32 bit Windows 7
- Broadcom R282233.exe if you have a 64 bit Windows 7
From : http://www.dell.com/support/drivers/us/en/19
The driver from dell site is Dell Wireless 1525 WLAN Mini Card Desktops.
But, although i have downloaded the driver, the thing is that i have a error message that the card isn’t started, or could not be found. What should i do in this case ? Check the bios to see if it is enabled from there ? I don’t know, because on the case there is no switch from which i can strat the wireless card. So maybe with Fn + 2, but i don’t know, we shall see.
I had an error, when i had to put some unicode characters in a property file.
The thing was that the JBoss application server wasn’t seeing the property file because of the contents. But i have found the solution only after i searched for a specification for a property file. So i found it on wiki:
It was a must that all four letters or numbers must be written with capitals.
So if we had \u00ea, it wasn’t good, because the parser was seeing ea like the property text, and the unicode couldn’t be unlocked, so the property file was invalid, and the application crashed, beacause of the property file. So i had to search for the places i’ve put \u00ea, and replace ‘ea’, with ‘EA’, so i think the problem is solved. Noob.
