I have a Servoy 7.4.3 installation (build 2036) which I wanted to update to 7.4.4 with the auto-update. However, when I selected the menu, Help/Check for Updates I get: "No updates were found."

I guess, this version is not still available through the auto-update. Correct?

it can be that the update site url of the release candidates: https://www.servoy.com/developer/70x_up ... ecandidate

is not there in your setup (it should be there if it was a 7.4.x install i think) or it is there but it is disabled
So if you want the release candidate enable that site.

Never mind, I don't want the auto-update for the release candidate in this specific installation. My mistake, I did not read "release candidate". I'll wait for the regular Update.

When do you expect release the final 7.4.4 product?

After upgrade to 7.4.4. RC I have a nullpointer exception within the webclient.
It is happening on the find/search and only when there are zero records found.

2015-05-07 22:36 http-8085-3 ERROR org.apache.wicket.RequestCycle null


It is difficult to debug this null pointer. It looks like it has to do something with rendering of the main form???

My debug results are:
1. The error is only happening when a find/search is returning zero records. Foundset 0.
2. When foundset is 1 or more records everything is working normal
3. Only when the view is tableview. With find/search in record-view everything is normal.
4. Smart-client is also working normal.

Is this a known error with the 7.4.4. RC?

what is really the full stack? (including the actual exception)
because it seems to be cut of a bit.

If i look at that stack you gave above then it looks to be not really the 7.4.4RC at least it seems a bit off

EDIT: i think the stack makes a bit more sense when looking at it a bit more,

There are two errors in the log. First: RequestCycle and second the rendering of the page.
Only happening when the foundset is empty.

I think also foundset.clear() is giving the same nullpointer.

Code: Select all

i think the request cycle thing is not really related to the nullpointer

We already have figured out why that happens, it is a regression because of the fix for this case: https://support.servoy.com/browse/SVY-7862
We will look int this,so it is fixed for the final of 7.4.4
