I had a Zope product that was working OK about a year ago. Now it's not. It seems the form action is not having any effect when I click on the button in the interface. As far as I can tell, the action is never called. I have tried this with Zope 2.4.3, which I think is the same version I ran before, and a fresh install of 2.6.1. One reason for the install was that I moved the entire application directory to a new drive in between, and I thought this might have caused some problems (I manually edited the paths I found). I also extended the app, but not in a way having any connection with the display of the form or action on it that I can see. I'm under MS Win 2k. When I type method calls directly into the browser (Mozilla) I call into the method or get a traceback if the name isn't recognized. But when I hit the action button on the form, I get no change at all except sometimes the URL gets the function arguments, e.g., http://localhost:8080/DSA/DSASync/DSASync/index_html?ignoreBlanks=ignore+bla... where the part from the ? on is new. (Not all tests have the DSASync/DSASync stutter). The dtml form is, in the relevant part: <form action="doddddCompare" method="POST"> <label>Ignore Empty Fields? <input type="checkbox" name="ignoreBlanks" value="ignore blanks" checked> </label><BR> <label>Keys <input type="text" name="key1" value="DSAID"> <input type="text" name="key2"> </label><BR> <input type="SUBMIT" value="compute differences"> </form> When I hit the form's button, I get no traceback that dodddCompare isn't found, and when I enter the real name (doCompare) I do not end up in the relevant method. I have verified that altering other text effects the form, so I am editing the right file and it is being picked up. The other odd thing is that I'm doing this as the root user created at Zope system creation. I thought such users could only create other users, but I'm able to create my object too. I've tried creating another user, but haven't been able to get past permission problems with it. The object statements that gets the form is index_html in the excerpt from the class def below: security = ClassSecurityInfo() security.declareObjectPublic() # added this to try to make things work # never was sure if this needed security # but I can see the form, so I'm OK, right? index_html = HTMLFile("diff", globals()) # here's the method that I'm trying to invoke security.declareProtected('View', 'doCompare') def doCompare(self, ignoreBlanks = None, key1="DSAID", key2=None, RESPONSE = None): # print statements in here never produce output # debug statements never induce a halt I would really appreciate any help, even advice on how to debug this.
