Links sometimes not working using JPT

I have developed a JSF application using the Java Portlet Tools. Everything seems to work fine most of the time, but ocassionally I will click on a link, an hourglass will be displayed but nothing ever happens. I'll refresh the page, navigate to the same link, click it again and it will work just fine. I've tried putting log messages in all the java code that I think should be getting executed and these log messages never get generated. It's almost like the portal just stops communicating with my application. Related to this, often I will click on a "Submit" button after changing a form and the portal page will refresh with my portlet completely empty. None of the submit code was ever executed. I'm running ALUI portal version 6.0. The java app is on a WebLogic 8.1 server. Does anyone have any ideas why this might be happening? - Thanks, Barry

I noticed early on that the inline refresh seemed to mess things up, so I had already turned it off. Most of the time, I am using <link> + jsf + jpt, but there are a couple screens where I am using a <button> for submitting a form. Both controls periodically fail.
I noticed in the link that other users were able to track what was happening using ptspy. I have used ptspy to send data to the support staff at BEA, but I have been unsuccessful at using it for my own debugging. It just seems to send back an overwhelming amount of data and I haven't found a good resource for knowing how to filter the results to find what I need. If someone knows of a good guide for this, especially specifically how it would relate to tracking problems with a JSF/JPT portlet, I would greatly appreciate it.

  • Text and links sometimes not working

    Ok guys, I'm fairly new at this website creation thing and it's giving me an achy skull. I'm publishing my site through godaddy, the domain is www.thegypsydave.com
    I've had to create the page 5 or 6 times now, luckily it's not very detailed. The problems i'm having are:
    When I publish it some of the links don't work
    When I publish it the text is in a different spot than it should be
    I think these are pretty basic things, but I can't figure them out and would be forever grateful for help. Though I think the website is appearing ok for now, though I tell you, it changes on its own account i swear.
    Thanks so much

    It does look ok now, but that's because I re-did it 5 or 6 times. Would it matter if i'd emptied my cache if i wasn't viewing it online but just from the folder that I published it in? Because the links and text weren't working then either. Though, like I said, I redid it a bunch of times until it worked.

  • Uploading Files Using InputFile Component -- Sometimes not working

    Hello,
    This is the 2nd time I make a post about it!
    Because I have more than 1 application using upload, and everything is correct! But it doesn't work as it should!
    You can check the original post here: Uploading Files Using InputFile Component - Sometimes not working
    I need a solution please!
    The only thing we can conclude is that it could be a bug from oracle !!! (???) But I talked with other people and they say that it works fine for them.
    There is one important thing: when we put a form to "Uses Upload = true" it seems that the page doesn't work very normal. For exemple: if you use a table in a form that uses upload the table get's "crazy".
    Thanks,
    JP

    I have now access to METALINK!
    I can find some problems and patches about inputFile but not mine! I will check better later!
    I think the problem is caused because of my framework!

  • [LAVA Cross Post] CTRL+SHIFT+ Shortcuts sometimes not working in LabVIEW

    Cross-post from LAVA: http://lavag.org/topic/15619-ctrlshift-shortcuts-sometimes-not-working-in-labview/
    See the above post for more information - here's a synopsis:
    CTRL+SHIFT modifiers are not working while running LabVIEW in a Parallels 7 virtual machine. This problem affects both LV2011 and LV2012. I'm not certain that this is a LabVIEW bug - could be an issue with my virtual machine environment or it's configuration - except that CTRL+SHIFT modifiers work in other applications on the affected VMs. It's just LabVIEW that appears to ignore shortcuts with the CTRL+SHIFT modifiers.
    Any ideas?

  • After updating to V 15.0 I have the issue that suddenly many but not all of the functions do not work anymore. Menues and download links do not work.

    I have updated my firefox to version 15.0. After this I have the effect that at some unspecified time during use many of the functions stop working. Menu's do not open, download links do not work anymore and so on. Opening new tab's or windows still works. Links on pages partly work partly not. Copy and paste does not work anymore on webpages. It takes ending the firefox process and restarting to correct the issue until it happens again. I have those effects on totally different webpages. At this time it happens every time after I start Firefox but not right away. Firefox first works for some time and then it suddenly doesn't anymore without me having done anything special

    The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
    Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
    To Reset Firefox do the following:
    #Go to Firefox > Help > Troubleshooting Information.
    #Click the "Reset Firefox" button.
    #Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
    #Firefox will open with all factory defaults applied.
    Further information can be found in the [[Reset Firefox – easily fix most problems]] article.

    Make sure that you not run Firefox in permanent [[Private Browsing]] mode.
    * You enter Private Browsing mode if you select: Tools > Options > Privacy > History: Firefox will: "Never Remember History"
    * To see all History and Cookie settings, choose: Tools > Options > Privacy, choose the setting <b>Firefox will: Use custom settings for history</b>

  • When I link to an external site, the link does not work, if I right click "Open in new tab" the link works.

    When I link to an external site, the link does not work, if I right click "Open in new tab" the link works.

    I have not changed any of my preferences and they look like they are as I would have left them.
    I tried resetting Firefox and deleting the preference file, no change.
    By the way, I hate that the tabs are on top and not where they belong above the pages they are for. There should still be a way in Firefox to put them back without having to use an add-in.

  • Links do not work RH5 to RH 8

    I upgraded a context sensitive, Oracle Help output, from RH5 to RH8.  Now several of the old topic ID links do not work. The links are not "broken" and some links within the same topic work and some do not. It gives the message that the address is invalid on the non-working links.  Also, the help system does not work when the "search" functionality is used.

    Dear jscher2000, thank you for your response! I'm running 16.01 version, so the 3.6.20 version isn't the correct one. I've updated it yesterday.
    I also have to mention that today everything seems to work just fine! :) I don't experience the problems anymore and all links work again just normally, eventhough I'm logged into Facebook account. Maybe it was just a temporary bug.
    I couldn't say what was the reason to that solution, but I'm glad there aren't problems anymore with Mozilla.
    Thank you again and best regards,
    Nina

    Hi Vikram
    Oh gosh, me and my big mouth!
    Patch 5381032 has two references to issues with links. You might want to discuss your scenario with Oracle and ask them if this patch would resolve your issue.
    Another solution would be to upgrade to 10.1.2.2 (available as a patch on MetaLink) which has most of the fixes from all of the patches applied. Again I would advise you speak with Oracle Support as they are the only one who can actually confirm whether this particular issue was fixed in this release.
    Are you by any chance seeing zero numbers display as 00 and are you seeing any graying out of icons? If so, then patch 5345595 (sometimes referred to as 5345528) fixes this and is a good patch to apply if you haven't already done so.
    All of these patches require a password which can only be obtained from Oracle by raising a service request to Support and stating the issues that you have.
    Hope this helps
    Regards
    Michael

  • Mark debug 'sometimes' not working

    I find mark debug sometimes not working.In my new project ,I add mark debug = true, then set up the debug nets.I can't find them in the assigned nets ,but from the netlists I find some of them.The missing nets are wire type,notregister type.Does the command not work on wire type nets?
    Because my project is very large, searching for the nets requires a very long time.So I hope Xilinx can fix this bug.

    Rather than open another thread, I'll extend this one since I'm having what I think is the same problem.
    I'm using Vivado 2014.4.  "Flatten" is set to "None".  The nets are set in the elaborated design with MARK_DEBUG and DONT_TOUCH.  But when synthesis gets done with them, the names are completely different.
    I don't care if the "equivalent" nets are still there.  I need the names.  Every time synthesis runs, it's a crapshoot whether the names will change.  Particularly bad are 500+ bit buses that get exploded into individual signals.  I don't have the time to regather them into the proper buses every time.
    In general, I've been pleased with the changes in Viviado.  But I can't believe how badly a wonderful tool like ChipScope has been screwed up.
     

  • ADF Tabe's Pagination link does not work when embedded in iframe

    Hi experts,
    When I embedded ADF table(with JSF) in iframe like below code, the pagination link does not work. Is it a known bug?
    <iframe width=100% height=500 src="http://rst-act3ct2.us.oracle.com:8888/test/faces/modify.jspx" frameborder="0" scrolling="no"></iframe>
    When I use <object> instead of <iframe>, the pagination works again. However, <object> could not be used in my project.
    Any idea on it?
    Thank you in advance.

    Hi,
    if you are on JDeveloper 10.1.3 then chances are that the problem can be pointed back to the mismatch of HTML and JavaServer Faces. At least you should make sure you work with a recent JDeveloper 10.1.3 release

  • XAV 601BT mirror link does not work at all ..app is crashing...its hopeless

    I am completely disappointed by this product of Sony. I had big regards for a brand like Sony and always believed that Sony delivers what they commit. But my heart broke when I installed this ****** stereo in my Honda car. The mirror link does not work on any compatible phone as they have shown in the box or website.<br>The App crashes system shows Device not detected. Tried many times.<br>So folks Dont buy this Mirrorlink ******....copy of this review is going to all major review sites..so people dont fall into this ditch.<br><br><br>

    I'm sorry to read about your disappointment with Sony Mikasony.
    I would just like to inform you that the available operations of  the MirrorLink function vary depending on the smartphone or the application being used. Therefore, some of the applications installed in the smartphone may not work when using the MirrorLink function. You can close the application and remove the USB connection between the smartphone and the car stereo then, reconnect again to resolve the issue. Here's the list of compatible devices.
    NOTE: For inquires about the application that is not working, contact the application vendor or the smartphone's manufacturer.
    Should you need further assistance, please reach out to Sony India Support here. Thank you!
