WebUI throws error for editing custom resources

Answered WebUI throws error for editing custom resources

    Hi everybody,

    I have added a custom model to Zentity, and I would like to be able to add my custom entities through WebUI. However, once I try to do this, I get an error. Here are the repro steps:

    1. Import your own model (i.e. I did this via XML file from RDF)
    2. Click on the custom entity (in order to add it)

    3. Error appears after click

    How can I fix this? Does anyone know? I'm going to check the docs again, maybe I missed something.

    Cheers,

    WizMan

    Hey Wiz,

    I have reproduced this bug at my end. I am currently investigating it and will get back to you with the updates.

    -Regards

    This is the stack trace: I would recommend to "Off" the custom error in WebUI web.config file

    <customErrors defaultRedirect="Error.htm" mode="Off">
     <error statusCode="404" redirect="Error.aspx?Error=PageNotFound"/>
     <error statusCode="408" redirect="Error.aspx?Error=Timeout"/>
    </customErrors>

    Wiz,

    I needed to copy the TestScholarlyWorks.dll fom the location C:\Program Files\Zentity\ZentityWebSite\DataService\bin to the bin folder of WebUI ( C:\Program Files\Zentity\ZentityWebSite\WebUI\bin ).

    Sorry for the delay Wiz.

    Thanks

    Hmm, after copying the .dll the WebUI worked, even the Metadata entry form for the entity appeared. However, once I clicked 'Save' the following error appeared:

    You might have got this point, the culprit here is the casting of the newly created resource as "Resource". No idea why this is happening. Need to do some investigation. Will update you once find any clue.

    Hi Wiz,

    The issue is due to no base type for the newly created entities. The database entry for the basetypeId is showing Resource type as the base type  but it fails in code. I have not tested the latest issue but it is due to the same reason. In the screen shot pasted in my last reply, the _resource variable will set to null when the highlighted line will execute. Below, two screen shots are compared, one for the newly created Scholar sample and one  for the lecture resource that comes with the Scholarly work. It just clarifies what I said above.

    In the above screen shots the hierarchies of both of the resources are shown. The lecture resourcew is well and shows the hierarchy as given in the Zentity database but the TestResearchDocument shows no Resource as its base type. I am not sure where the code breaks. I will start researching again and will update you in next 12 hours. Also, by the time, if you find some trick to overcome this issue please share with us on the forum.

    Hope we resolve this today!

    -Regards

    No luck Wiz. Need some more time. I will keep you posted on the updates.

    Ok, I understand the problem as you've described it and thanks for the update! I am also working in parallel to attempt to solve this. I've tried creating a custom entity via code which definitely inherits from the type Resource (explicit base type), but I receive the same error still. Maybe you have more luck than I do tomorrow :(

    Cheers

    I need to confirm with the Zentity product team before responding to your this query and overall guidelines on your observation "why Zentity generally dislikes models other than ScholarlyWorks", posted in the other thread. Will keep you posted on the updates.

    -Regards

    Hi Wiz,

    The above issue cannot be solved under "Zentity Design". The Zentity.Platform project is tightly associated with the Zentity.ScholarlyWorks and so is webUI. Zentity Resource Manager is a way of overcoming this limit for custom resources and data models.

    Please let me know, by accepting it as answer, if I can close this issue now.

    -Regards
