Cannot change PopUp LOV width and height in version 4.2.5.00.08. I change the values of 450 400 in the Popup list template values (Section of the window), but my function genList0_f07_$ _row (), retains the same settings. Is this a bug?

Hello

I use APEX 4.2.5.00.08 to my app.

I have a region of reports, where I display a column set. A column is the column attribute "display as" the value 'Popup LOV (LOV based query).

I press the button to retrieve the LOV, I get a popup of 450 x 400 pixels.

I go to the side of the model and navigate to "Popup list of values of model", where I can see in the section 'Window' attributes 'Width' and 'Height' value 450 and 400. I edit them and save them and there is nothing going on. I'm sure that the template belongs to my selected theme.

I saw in the HTML source code that is the called function:

<!--


function genList0_f07_$ _row)
{
w = open ("wwv_flow_utilities.gen_popup_list" +)
« ? p_filter ="+
"& p_name = ' + escape ('f07') +.
' & p_element_index = ' + escape ('0') +.
' & p_elem_id = ' + escape ('f07_0000').
' & p_form_index = ' + escape ('0') +.
' & p_max_elements = ' + escape ("") +.
' & p_escape_html = ' + escape ("") +.
' & p_ok_to_query = ' + escape ('YES').
' & p_flow_id = ' + escape ('114') +.
' & p_page_id = ' + escape ('100201') +.
' & p_session_id = ' + escape ('16021544706004').
' & p_eval_value = ' + escape ("") +.
' & p_translation = ' + escape ('NO') +.
' & p_lov = ' +.
' & p_lov_checksum = ' +.
' & p_item_id = ' + escape('-683997768') +.
' & p_column_id = ' + escape ('25022622060292812'),
"winLov,"
"Scrollbars = 1, resizable = 1, width =400, height =450"); "
If (w.opener is nothing)
w.opener = auto;
w.Focus ();
}
->

I see that the values has not changed. I also connected and disconnected. I am inclined to believe that it is a bug of the APEX.

The only solution I think is to replace this function, which is NOT ideal.

Thank you

The parameters are generated only, nothing you can do about it because it does not use the model for these properties of the couple. Other things work fine for example the names of button or title window etc. I guess that, Yes, it is a bug. It's still there in the apex 5 too, I checked. The default values of the template do not match, the value in the generated code is always 400/450. So I guess it's pretty much a wait on 5.1.

Here's a fun hack to make it work well on your page (works in apex 5 too, because the code is always the same). Put this in the execute on loading of the page section:

(function(){
  var _open = window.open;
  window.open = function(){
    if ( arguments[1] === "winLov" ) {
      arguments[2] = "Scrollbars=1,resizable=1,width=500,height=700";
    };
    return _open.apply(window, arguments);
  };
})();

Change the settings to your liking. This will replace the existing window.open call, which is what the popup lov use and replace it with our own code. It does not interfere with other things. As the name of the new window is always "winLov" for the popup lov, it is the argument that is checked.

During the call to window.open to open a new window with the name "winLov", parameters are replaced with your own version of it. The window is called as usual, using the stored reference.

Edit:

Yes, do not use the trick of resizing. My hack can be a bit tedious, but it's much less invasive for the end user (see open, bam, resize. "Even gets funky on multiple monitors). Also, this thing in the popup lov template will affect each lov popup that you use in the application, which is much less interesting than my specific page code.

Edit2:

I did a little digging in the source code, and I don't know why it does not work. Popup lovs are actually equipped to deal with it. My guess is that the parameters are recovered only after that the lists were generated, causing the package variables global to use their default values instead of model parameters.

  • Sound problems on computer, cannot change the sound settings

    I had a long-standing problem in the audio settings of the Control Panel on Windows 7 where I can't change settings, configure anything or especially toggle of the devices. The options are there, but they have no effect when selected. Recently, I tried to connect my laptop to a TV, and as I could not set as the default audio device, I finally decided to try to fix things. I deleted and reinstalled the software Realtek my laptop and everything he has done is completely turn off my speakers, and all attempts to reactivate failed them. The unit displays in the control panel as a default active device, but claims of the taskbar that there are no speakers is connected, and if I click to set up the Realtek Audio, I have the same situation that before where absolutely nothing is happening.

    I tried troubleshooting sound problems, and all I get is the statement that an audio device is disabled, no attempt to fix or any option to enable. Apart from a system restore, that in general, I try to avoid, I feel that I have tried everything I can think of to fix this and only managed to make it worse. No help available would be appreciated to receive my laptop back to a functioning State.

    Can someone help me to unlock the screen saver settings (remove the grey shadow) so that I can customize my screen saver?

    Thank you

    1. are you able to click on the dropdown under screen saver?
    2 or it is dimmed as well?

  • Cannot change the print settings

    I have a new printer, an Epson XP 430. My previous printer was also an Epson. With my old printer, when I chose to print (for a document, web page, etc.) the dialog always had an option to choose, black and white. I also could add to the presets and edit presets.

    With this printer, I can see the presets, but I can't make changes. When I click on view Presets, it is not an option for adding a new preset as it was with my old printer and remove and duplicate boxes are grayed out.

    I guess that this is due to the printer, not OS X, as I noticed the difference when I started using the new printer. Am I missing something somewhere? I rarely print in color, so I would have a preset that specifies black & white.

    Thank you.

    Sheri

    Since you have a new printer, you can create new presets. This is done through the printer with the selected printer dialog box, not through the page view Presets. When you select this option to print do the settings that you want to create a preset for and then click on the drop down preset menu. Select "Save current settings as preset" and enter a name for the new preset.

    How am I able to change the width and height parameters (to make the title more high definition) , without having to create another title in replacement from that Fuzzy? I don't ask if I have to create another title and insert it in the video, and then having to erase those blurry I had to replace. How are you able to change settings of the original title, without having to make a new title? Should I go to the 'Properties' tab when there is nothing at all (as in there is no option to change the w + h title quality) to change the current settings of the title?
