I have deployed an ASP.NET 2.0 application that is using neadvantage 7.1 for ASP.NET. Sometimes randomly, when a page that contains webdatechooser control is loaded, the following error occurs:
Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:Arial; mso-bidi-theme-font:minor-bidi;}
Object reference not set to an instance of an object. Stack Trace: at Infragistics.WebUI.Shared.WebAgent.GetPageControl(Control control) at Infragistics.WebUI.Shared.WebAgent.get_EnableAppStylingResolved() at Infragistics.WebUI.WebSchedule.WebDateChooser.get_IsAppStyling() at Infragistics.WebUI.WebSchedule.WebDateChooser.OnPreRender(EventArgs e) at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
The user can go further unless the IIS server is restarted. As you can see, all the method call that are involved in the error are from Infragistics and .net framework. Any clue on how to solve the problem?
Note: Sometimes the error appears for other infragistics control such as ultrawebgrid etc.
Vincent,
As you suggested, I submitted a support request on October 19 (CAS-33676-ZVN3T1).
It is going on 4 days, and the status of the support request is still "Awaiting Assignment".
How long does it take for a Infragistics to reply to a support request? This issue is still taking down the website without notice at random times, and I have to remain on call 24 hours to reset the server each time it goes down due to this bug.
If there is an interim build that corrects the issue, I would really like to obtain it before we go into the weekend.
robhudson2,
If you haven't already done so, I recommend that you submit a support request, as I mentioned earlier in the thread. I suggest this for two reasons.
First, if the cause of your issue is the same as what's already been reported, we can link your case to an existing development issue (21987) that was raised based on cases logged by others earlier in this thread. We've applied a fix for this issue internally, which we expect to be included in the next service release we publish, assuming that it passes our testing process.
Second, we can investigate to determine whether your issue is the same as what has already been reported. If it's a different issue, then this upcoming service release may not help you, and we'll need to research your issue in more detail to bring it to a resolution.
I am having the exact same issue... would love to hear if Infragistics has produced a fix or workaround.
Part of my message got clipped. Trying again...
* html img,
* html .png {
position:relative;
behavior: BLOCKED EXPRESSION;
}
Not sure if this is a coquincedence or not, but we had added an IE 6 fix for png files when the problem started showing up (see below). Once I removed that the problem went away and we've been error free for at least one day now.
