Re: show image retrieved from database
I've been searching for solutions on how to show an image using its
location(absolute path) and your code helped me a lot. Been under stress the
past days due to this problem. Thanks Mr. ORACLEADF!
Btw, for those who wants to know how to convert a File() to byte[] use this:
try {
File file = new File(imagefilePath);
byte[] byteArray = new byte[file.length()]();
byteArray = FileUtils.readFileToByteArray(file);
}catch(Exception e){
e.printStackTrace();
}

Re: AjaxRequests and middle mouse-clicks on links and buttons
Hi, I don't use a mouse (and I have no one around) so I cannot test the use case. I cannot see how org.apache.wicket.ajax.markup.html.form.AjaxButton#onSubmit(org.apache.wicket.ajax.AjaxRequestTarget, org.apache.wicket.markup.html.form.Form) or org.apache.wicket.ajax.markup.html.AjaxLink#onClick(org.apache.wicket.ajax.AjaxRequestTarget) would deliver null as a target. The target is created at org.apache.wicket.ajax.AbstractDefaultAjaxBehavior#onRequest(). Put a breakpoint there is see what happens. Martin Grigorov Freelancer, available for hire!

Re: Issues with multiple FeedbackPanels
Hi,
Feedback panels show all messages by default. You will need to provide a
way for them to filter the messages that each should show.
Look at FeedbackPanel#setFilter(IFeedbackMessageFilter).

AjaxRequests and middle mouse-clicks on links and buttons
Hi all, I have a problem here, I would like to ask you for feedback. I am not sure, if its more a jquery/js / wicket issue, so thanx in advance for any brainstorming and hints. Browsers often features the middle mouse button to open a link or button in a new tab. This is quite browser-specific, so I'm looking for the most independent solution. Clicking the middle mouse on a ajaxified Link or Button, the browser opens a new tab and starts a usual request cycle. This leads into wicket call e.g. onClick(AjaxRequestTarget target) but then the target parameter is null. (I cannot use AjaxFallbackLinks in my case) I'm able to handle this NPEs by implementing null-checks on every ajax link. Hmm... not the perfect solution. So, I could try to prevent middle mouse clicks by a global javascript on all pages. I've seen several scripts, and here also it seems to be very browser-specific (mousewheel, or not... event.which seem to differ and so...). Also, not my favorite solution, yet. Then I thought about wicket solution. Is there any possible way? I know about a IComponentOnConfigureListener, which can be used to have to implement an application-wide onConfigure() for any component in page hierarchy. Is there something siilar e.g. IComponentOnAjaxRequestListener? So I could implement some code there, checking for null and stop any further code-calls on ajaxified wicket components, to avoid running into NPEs in later code? All these are my thoughts for now. Thanx a lot for feedback... kind regards Patrick - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Wicket in web-fragments environment
Hi Martin, while creating the quickstart the problem disappeared. Its working. I figured out, I had some wrong configurations in my m2e eclipse project specific settings while migration my project structure to web-fragments structure. Due to that my classpatch settings were wrong and packaging of jars were incorrect. ;-) kind regards Patrick Am 17.03.2015 um 10:47 schrieb Martin Grigorov: Oh, right!

Issues with multiple FeedbackPanels
Hi, I have 2 FeedbackPanels on my screen and whenever i try to set error it
gets added to both the FeedbackPanels.
final FeedbackPanel panel1 = new FeedbackPanel("panel1");
final FeedbackPanel panel2 = new FeedbackPanel("panel2");
//vdp & gdp are some dataproviders i have
if (vdp.hasError()){
toonMeer.setVisible(false);
vertegenwoordigdeMelding.error(this.funcMeldingen.getMessage(vdp.getErrorcode()));
vertegenwoordigdeMelding.add(new
AttributeModifier("style",
"color:red"));
vertegenwoordigdeMelding.setVisible(true);
}else if((int)vdp.size() == 0){
vertegenwoordigdeMelding.info("U bent door niemand
vertegenwoordigde");
vertegenwoordigdeMelding.add(new
AttributeModifier("style", ""));
vertegenwoordigdeMelding.setVisible(true);
}
if (gdp.hasError()){
toonMeer2.setVisible(false);
gemachtigdeMelding.error(this.funcMeldingen.getMessage(gdp.getErrorcode()));
gemachtigdeMelding.add(new AttributeModifier("style",
"color:red"));
gemachtigdeMelding.setVisible(true);
}else if((int)gdp.size() == 0){
gemachtigdeMelding.info("U bent door niemand
gemachtigd");
gemachtigdeMelding.add(new AttributeModifier("style",
""));
gemachtigdeMelding.setVisible(true);
}
I have a listView as well which sets the error in certain scenarios:
if(this.panel.equalsIgnoreCase("panel1")){
this.getParent().getParent().get("panel1").error("some message");
this.getParent().getParent().get("panel1").setVisible(true);
}else{
this.getParent().getParent().get("panel2").error("some message");
this.getParent().getParent().get("panel2").setVisible(true);
}
The code works but the messages are displayed in both the FeedbackPanels.
Could you please guide me in right direction?
Thanks.
