Re: AutoCompleteTextField and change AjaxFormComponentUpdatingBehavior

[Zbynek Vavros]

I'm not sure we understand each other.
Such a behavior is already there using AjaxFormComponentUpdatingBehavior
("change").
This way ajax is triggered ONLY when value is selected from choices (either
by mouse or by keyboard).
= exactly what I want.

I tested this in small prototype and it works just fine.

My issue is that this doesn't work in our business app so I am trying to
find why this works in prototype app
but not in business app (as I mentioned both use wicket-core and
wicket-extensions 7.0.0).

What I found out is that in both cases (prototype and business app)
the event in line 178 in wicket-autocomplete.js is invoked as expected. The
issue is that business app does no ajax call after that.

To summarize all I would like is some help with JS debugging since I am
java-dev and js-noob :(

Re: AutoCompleteTextField and change AjaxFormComponentUpdatingBehavior

[Martin Grigorov]

At the moment wicket-autocomplete.js triggers event with name "change":
https://github.com/apache/wicket/blob/580d92ddf068040214669c085f54d2faa702a921/wicket-extensions/src/main/java/org/apache/wicket/extensions/ajax/markup/html/autocomplete/wicket-autocomplete.js#L446

This makes it hard for the application to know whether this is a normal
change event for the  or the manually triggered from selection from
the dropdown.

I am not sure how it works for the simple app. I have to try it to see what
happens.

Re: AutoCompleteTextField and change AjaxFormComponentUpdatingBehavior

[Sven Meier]

Hi,

wicket-autocomplete.js surpresses the "change" event while you operate 
on the drop down.
When it decides that your selection has finished (e.g. the drop down is 
hidden), the "change" event is triggered subsequently.


The AjaxFormComponentUpdatingBehavior will pick up the "change" event 
and do an Ajax request as usual.


Hope this helps
Sven

Just out of curiosity, I see in wicket-autocomplete.js that the onchange

How is this handled afterwards ? I mean how does it get from here to
calling the ajax ?

Thanks!

To support use cases like yours it has to trigger some custom event too,
e.g. "itemselected.wa" ("wa" is a sample namespace for
wicket-autocomplete). The you can use
AjaxFormComponentUpdatingBehavior("itemselected.wa").

You can use Ajax throttling to avoid sending requests on every typed
character but only after N ms after the last typed character. See
AjaxRequestAttributes#setThrottling() for this option.
There is no magic that will read your users' mind to tell whether an
entered value is final or not.

Re: Lots of files in temp folder

[Martin Grigorov]

Hi,

The folder for the session data (filestore) should be removed with the
invalidation of the user session (either expiration or explicit logout).
But there must be one such folder in /tmp with many sub-folders.
Here it looks like:
/tmp/jetty-0.0.0.0--webapp-_myapp-any-/
└── MyApplication-filestore
└── 2200
└── 5314
└── 1i0svs4a1edbvdenm01kfwyzy
└── data

Whenever a user session is invalidated a branch should be removed.

The "file-prefixtmp" file I believe is created by commons-fileupload.
It supports file cleaner which by default removes the files when the Java
process terminates, e.g. when you restart your web server.

Re: AutoCompleteTextField and change AjaxFormComponentUpdatingBehavior

[Zbynek Vavros]

What I mean by final value is value selected from list of options.
The OnChangeAjaxBehavior you suggested will do ajax on every key stroke.
So lets say my autocomplete display list of cities.
I want the method called when user selects a value "London" from list.
Not on each stoke "L", "Lo", "Lon"...

As I said, this is because I need to use the selected value for additional
processing.

Re: AutoCompleteTextField and change AjaxFormComponentUpdatingBehavior

[Martin Grigorov]

Hi,

How do you decide when "final" value is entered ?
You can use Ajax throttling to avoid sending requests on every typed
character but only after N ms after the last typed character. See
AjaxRequestAttributes#setThrottling() for this option.
There is no magic that will read your users' mind to tell whether an
entered value is final or not.

Re: AutoCompleteTextField and change AjaxFormComponentUpdatingBehavior

[Martin Grigorov]

OK. I understand now.
Looking at wicket-autocomplete.js I see that it triggers "change" event
after click on an entry.
To support use cases like yours it has to trigger some custom event too,
e.g. "itemselected.wa" ("wa" is a sample namespace for
wicket-autocomplete). The you can use
AjaxFormComponentUpdatingBehavior("itemselected.wa").
Please create a ticket in our JIRA!

Re: AutoCompleteTextField and change AjaxFormComponentUpdatingBehavior

[Zbynek Vavros]

Hey,

sorry for not explaining properly...
I already tried that and in this case the the ajax call is triggered
on "inputchange" as well, meaning on every key stroke.

This is not desirable because we use the value of this autocomplete field
to calculate value of another fields in form. This calculation should
happen only
when "final" value is selected.

Re: AutoCompleteTextField and change AjaxFormComponentUpdatingBehavior

[Martin Grigorov]

Hi,

It is not very clear what exactly is the issue.
As far as I understand the problem is that the Ajax call is triggered only
when you navigate to another form field. If this is the issue then try by
using OnChangeAjaxBehavior instead of AjaxFormComponentUpdatingBehavior.

Lots of files in temp folder

[Manfred Bergmann]

Hi.

I had a case where a customer had millions of file in Java tmp folder
produced by Wicket.
There are a lot of those folders:
"org.apache.wicket.protocol.http.WicketServlet-128f3c8-filestore", etc.
and
"file-prefix59601103483491554.tmp".

Most files are very small but the sheer number of them gave them a size of a
couple of giga bytes.
This is not actually a large application. It has two or three pages with
components.

The number of temp files probably has grown over a large period of time
where the Wicket page was always open in a browser and got reloaded often.

Are those files not removed from time to time, automatically?
If not, how can I remove them programmatically?

A, yeah. the Wicket version is 6.19.0. Upgrading to 6.21.0 shows the same
behavior.

Regards,
Manfred

Re: Lots of files in temp folder

[bilguun]

Hello, 

I realized those files are removed when session is expired due to the user
inactivity and main method that removes those files is a method unbind() of
static inner class
org.apache.wicket.protocol.http.pagestore.DiskPageStore.SessionEntry. But if
user explicitly logout, it does not delete those files using only
invalidateNow(). So do I have to call that unbind() method manually to
delete those files? 

Thanks,

Bill

Re: Lots of files in temp folder

[Martin Grigorov]

OK.
This looks like a bug too.

grep says:
wicket-core/src/main/java/org/apache/wicket/settings/StoreSettings.java:
fileStoreFolder
= File.createTempFile("file-prefix", null).getParentFile();

So it seems Wicket creates a temporary file just to get a reference to the
/tmp folder and discards this file.
We should delete it!

Are those files empty on your system?

Re: Lots of files in temp folder

[Manfred Bergmann]

Hi.

Yeah, the filestore.
Hmm, there is no file-upload functionality in this Wicket app. I'm wondering
why those file are created then?

I just had a check. There were 8GB of data from those files.

AFAIK wicket serializes old version of pages into file system

Re: Lots of files in temp folder

[Martin Grigorov]

The "data" files with its parent folder must be deleted automatically when
a session is invalidated either by calling #invalidate[Now]() method or due
to inactivity of the user.
If the file is not removed then it is bug in Wicket that should be fixed!
Please create a quickstart application that shows the problem and attach it
to a ticket in JIRA! Thank you!
