Re: [Zope] Problem with adding items to ZClass instance
I don't think there's anything "special" about my ZClass. It's derived from Catalog Aware and ObjectManager. I believe I reproduced it without the Catalog Aware and got the same results. I'm using Andy Dustman's version of the MySQLDA and TinyTable v0.8.2. They both work just fine once I get the objects in the right place. Maybe the problem just happens to be with these two products, but I have no clue. You're welcome to fetch the product at ftp://ftp.logicetc.com/pub/Zope/IssueTracker.zexp if you want to give it a look. It's a one day throw-together port of the issue tracking system used by the PHP project with modifications for my own needs. OK, I downloaded it and I think I found your problem (not wure how to remediate this, though). If you look in the source of the management screen http://localhost/somefolder/IssueTrackerInstance/manage_main, the dropdown list for adding Product looks like this: FORM ACTION="http://localhost/somefolder/IssueTrackerInstance/" METHOD="GET" SELECT NAME=":method" ONCHANGE="location.href='http://localhost/testhier/blup/'+this.options[this.selectedIndex].value" OPTION value="manage_workspace" DISABLEDAvailable Objects OPTION value="manage_addProduct/OFSP/documentAdd"DTML Document OPTION value="manage_addProduct/OFSP/methodAdd"DTML Method OPTION value="manage_addProduct/MailHost/addMailHost_form"Mail Host OPTION value="manage_addTinyTableForm"TinyTable OPTION value="manage_addProduct/OFSP/manage_addUserFolder"User Folder OPTION value="manage_addZMySQLConnectionForm"Z MySQL Database Connection /SELECT INPUT TYPE="SUBMIT" VALUE=" Add " /FORM As you see, most of the items have a manage_addProducts/ as a start. Not so with TinyTables and MySQLConnection. They call the add_TinyTableForm and manage_addZMySQLConnection form. They do not switch the namespace to manage_addProduct (not in the form). Why this is a problem, I can't tell, but this _is_ the problem. I'm not quite sure about the solution. Probably it's best to make a custom manage_main form that does the right incantations for adding products and then map this to your Contents View in the ZCLass definition. As a side I'd like to remark that all products should comply with the same manage_addProduct interface, because the current situation leads to nasty problems.

To be sure I added a tiny table plus to an instance not a straight tiny table and a ZODBC adapter, but I doubt whether this would make a difference. Anyway, they both work straight away. This is getting very strange indeed. It seems strange things are happening to your namespace. I can think of some things that may cause problems, but this is all speculation. This may be a bug, but then it's a special one. Anything special about your ZClass - what does it derive from (just objectmanager? anything else that might cause strange behaviour?). Is there a subobjects tab in it's definition? Are the products in there?

Re: [Zope] Problem with adding items to ZClass instance
I discovered something bizarre that happens in my 2.1.4 and 2.2b1 installations. Bizarre, yes, unusual, no. I have a ZClass based on ObjectManager. In an instance of the ZClass, I can "Add" most of the available objects (DTML Documents, DTML Methods, User Folder, MailHost to name a few). However, for at least two items (TinyTable and ZMySQL DB Connection), when I add them, they show up in the container folder, not in the ZClass instance. Then, if I check it to delete it, it gives a "does not exist" error. Upon refreshing the container folder, the item still shows, but then I *can* delete it. Equally interesting is that I can Copy the item from the container folder and successfully Paste it into the ZClass instance. However, since ZMySQL DB Connections don't support Copy/Paste, that won't work. What's going on? Is it a problem with my ZClass, the Product manage_add, or Zope? Or me? This is not so easy to answer. ZClasses do strange things to adding items. If your ZCLass definition (in the Product) is nested in another ZClass, then it is your ZClass.
