Assessment of EL expression for game on AMX results page empty

Hello
I have a REST service with some search criteria. If the search criteria fits well, I'll get a set of results to display on a page AMX. If the search criteria are too narrow, I get a message from the REST service and the result set is empty.
In this case, I want to display a message (outputText) that the search does not work. I try to define an EL for the 'Rendering' property using the keyword 'empty '. But all my attempts so far using bindings. FlightsEntity.collectionModel or bindings.findFlightsByParametersIterator have failed, that is, these objects are not empty in this case. Unfortunately, CRG does not evaluate EL in debug mode to see which expression would give the desired (true) result.
All tips EL expression I could use to test for an empty results set?

Kind regards
Jürgen

Try this:

#{bindings.yourIteratorName.iterator.totalRowCount == 0}

    Hello

    If you want to use the laptop for games, I recommend buying one with an external graphics card. Means the graphics card should not be a part on Intel CPU (Intel HD GPU) but you must choose the laptop with a chip graphic ATI or nVidia GPU.

  • HP PAVILION 17-F061NB: for games cooling pad?

    Right then, the story made short: I recently (a few months), bought a HP Pavilion 17-F061NB computer laptop computer laptop, which I use mainly for games. It has a processor AMD A10, with 12 GB of ram, and and AMD Radeon R7 M260 dedicated graphics card. Shortly after I bought it, (first day), in fact, I felt that the laptop has been hot all game, sometimes even simply watching videos.  (I'm playing minecraft, life is feudal: your own, battle field 4 (a little)).  So recently I've been thinking, it would help if I bought a GOOD laptop cooling pad? I use my laptop on my desk, not on my knees. I don't have any tips/advice on the cooling pad, I can understand that for my part, I'm just curious if these things help you or not.

    I have two of the coolers below; I was happy with the performance.   They have been used to cool HP dv7t 17 "computers laptops running 8 GB of RAM, Intel switchable graphics card.

    I do not 'game'; I'm doing some work that pushes the graphics system and the memory of Photo editing.  Photo editing is not the same thing as the game; former dv17t model HP notebooks run hot, so there may be some use for the comparison.

    Option: Connect the laptop cooler to a Powered Hub from Siig.  The cooler provides its own on/off switch, which allows you to turn it off when you don't need it or when you are finished using the system.  Of course, don't forget to turn off the radiator when you connect the cooler to an arrangement of external hub.

    I'm looking to upgrade my processor for games. I currently have:

    CPU: Intel Core i3 4130 (dual-core) synchronizing to 3.5 GHz (socket LGA 1150)

    Mobo:HP 2AF7, Intel Haswell H87 Chipset rev 06

    Is there any particular processor (preferably less $ 200) which would be good for gaming?

    Please let me know what you recommend.

    Thank you

    Hello

    Review the processors that are updated approved for HP 500-270.

    I suggest that you consider using a discrete graphics card before the upgrade of the processor.

    Consult this publication of the article.

  • AMD A6 Series: How to speed up my laptop for games

    Product number: How can J5t41UA #ABA I speed up my laptop without losing too much money?

    Andres2

    To provide a little explanation, there is really little of anything you can do with a laptop.

    To speed up your desktop for games, you could consider all the following:

    (1) upgrade the current processor to a more powerful and faster that remains compatible with the motherboard

    2) install faster memory - if it is available and if the motherboard will handle it.  If the faster memory is not available, then the current memory overclock (and if necessary, the CPU as well)

    (3) install more memory - if you use very little, say 1 GB

    (4) replace the integrated graphic card graphics high-end focus on the game - which will be VERY expensive!

    (5) replace the hard drive with one of the new, high-end SSD

    In a laptop, you can often add more memory, but not enough to actually help gaming performance; and also, you can replace the hard drive with an SSD.  But even in this case, comparative tests have shown that game by using an SSD does not result in the improvement of the notable performance during the game with a hard drive at high speed.

    So, basically, no, there is really nothing you can do to turn your laptop into a game machine.

    Graphics chips for this type of laptop computers are soldered to the motherboard. The only way how to change is to replace the motherboard with a compatible one equipped with a more powerful chip. See the manual.

    Hello HKaurND,

    All updates before April 8, 2014 will be always available for download via the Windows updates if you decide to reinstall Windows XP. Thanks to Microsoft to no longer support XP after April 8 you'd be advised to upgrade to a newer version of Windows, i.e. Windows 7/8.1

  • If I want Outlook Express for my e-mail how do downloaded?

    On my other computer that I want to get Outlook Express for my e-mail, how it downloaded?

    OE is a part of XP, and you already have it.
     
    Go to control panel | Add/Remove programs. Add/Remove Windows components. Make sure Outlook Express is checked.
     
    Still nothing on the desktop? Copy this:
     
    c:\Program files\outlook express\msimn.exe
     
    Start | Run and paste it in. Ok.
     
    Now go to control panel | Set access to programs and settings by default and OE set as default and then you should have the shortcut.
