Dynamic fields is hiding all the fields in the ticket summary

[matthewf@…]

Our trac project has been upgraded to trac and the dynamic fields plugin is now hiding all the fields in the summary (the part when the fields are edited is correctly showing the subset of fields). If any field has the x.show_when_type=y or x.hide_when_type=y specified in the trac.ini file then the field is hidden.

Installation info is listed below. Any help in resolving would be greatly appreciated.

Please provide a minimal sample [ticket-custom] section that reproduces the issue.

Thanks for looking. This is a snippet from the ticket-custom section. If the show_when/hide_when lines are commented out then the field is shown, otherwise it is hidden, even if it should be shown (at least when I think it should be shown). If necessary I could probably get you access to the system, which is running Ubuntu 16.04.

[ticket-custom]
cc.show_when_type = test|pr|documentation|devel|project

doc_type = select
doc_type.label = Document type
doc_type.options = |app_note|brochure|integration_db|manual_update|price_list|release_notes
doc_type.order = 90
doc_type.show_when_type = documentation

duration = text
duration.label = Hours spent
duration.order = 70
duration.hide_when_type = eco

[Ryan J Ollos]

The configuration works fine for me with Trac 1.0.9. Most likely you have a plugin conflict ​TracTroubleshooting#ChecktheBrowserConsole). You can try disabling all of your plugins, and if it works enable them one-by-one until you find the plugin that breaks the configuration.

Make sure you are running the latest DynamicFieldsPlugin. I bumped the version just now (2.1.0dev -> 2.1.0) and published to ​pypi:TracDynamicFields.

You are running some very old versions of plugins. I suggest going through all your plugins and upgrading, particularly for MasterTicketsPlugin and SpamFilterPlugin.

Thanks again for investigating.

Using the Ubuntu 16.04 package system to install Trac gave Trac version 1.0.9, with all the plugins previously listed. I have had another attempt at this, but using Trac 1.2.1 and only the dynamic fields plugins and, surprisingly, I am getting the same behaviour: the description is only showing the reporter and owner fields and the modify ticket section is showing the correct subset of fields.

So this time the install is streamlined to a single plugin with the latest trac. This is the about info:

This is a snapshot of the browser (Chrome) with the developer tools showing the hidden fields:

As far as I can tell this is a minimal configuration, but I'm still seeing the problem. Can you see anything that is obviously wrong?

[Ryan J Ollos]

Is your [ticket-custom] section the same as in comment:2? I think it's probably the issue described in #12575.

[anonymous]

I have tested with a single custom field, eg:

[ticket-custom]
duration = text
duration.hide_when_type = eco
duration.label = Hours spent

and a single pre-defined field, eg:

[ticket-custom]
cc.show_when_type = test

In both cases it causes the field to always be hidden. #12575 doesn't have much details. Is there anything I can feed back to you to resolve this? Could you point me in the direction to look for the problem (I'm afraid I have basically no experience with Pyhton, Javascript and jQuery, but I'd be happy to have a look and help if possible).

[anonymous]

Been testing a bit. If clear_on_hide is set to true (the default) the field is always hidden. If clear_on_hide is set to false the field is always shown. This seems to tie in with rule.js:169 onwards. That's as far as I have got.

[Ryan J Ollos]

The plugin interacts poorly with preview and autopreview. I think it's going to take some work to fix this and not sure when I'll have time to work on it.

[anonymous]

Hi Ryan. It is not in the preview that the fields are being not being shown, but in the ticket ticket description block.

I'm having the same issue after a Trac upgrade to 1.0.13 from a much older version. Anything with a show_when_type is not displayed in the read/display portion of the ticket at the top (yellow). OP, if you look back here - did you find a resolution to this?

Hi. No, I never resolved this with the dynamic fields plugin. I ended up using the KeepInterfaceSimplePlugin.
