The SEARCH dies when handling TWiki:Plugins/OoProjectPlannerPlugin, which has this meta data:


It dies on a field named title="*Deprecated*". The TWiki:Plugins.PackageForm had this field for a short time, such as version 40, TWiki:Plugins/PackageForm?rev=40

It looks like there is an issue with missing escape of meta characters.

-- PTh

And no, please do not discard this because of "missing test case"

-- PTh

FYI, Cairo has the same bug.

-- PTh

Even from looking at the code I cannot see what the title attribute vs name attribute in the META for forms is used for. How do you get the different value there in the first place. title is always same as name no matter what I have tried

KJL

Ken, the title attribute gives the literal spelling of the title. The name attribute is the title reduced to alphanumerics. In addition, when the [[][]] format for fields is used, then the name has the real name there, while the title has the display name. It is easy to get them to be different.... -- TW

Yes. I see now. And I have seen how the two can be made different in practical. Still need to look further at the bug.

KJL


Please look at the attached FormProblem3.txt. I do not get the problem you describe on this variation. Note though that the "*" do not render the title bold faced. -- TW

Marking this as "Confirmed" as it's definitely a bug.

CC

It was actually the rendering of the formfield that gave the problem. Fixed by quoting mata in the search.
