Plugin is not working for trac 1.0.4

[torsten.piotraschke@…]

I built the egg on the machine that is running trac and rebooted the machine. But using hide_always still shows my custom field in the new/edit ticket form and in the ticket view. I can see the plugin activated in the Admin-Web-UI.

Since I've nowhere read of such trouble, I guess I've simply installed it wrongly. However, I have no clue what installation part is missing.

Tested with

• Chrome 41.0.2272.76
• Firefox 36.0
• Opera 12.16

Could you try disabling your plugins one by one, restarting the server each time and testing?

[torsten.piotraschke@…]

I'm not able to restart the server at the moment.

However, also by not restarting I could narrow the error down to the following module: DynamicFieldsModule — A module that dynamically alters ticket fields based an extensible set of rules. Uses jQuery for full implementation.

Since it also states that it uses jQuery and the error above points to a jquery error, I guess this is the cause.

If I deactivate that module, there's no error in the console. If I activate it, there is.

With the mentioned setting I just restarted the server and still the plugin doesn't work.

I used the hide_always = true feature, but the text-field is still visible. There's no error in the browser console and the log says the plugin gets loaded.

[Ryan J Ollos]

You need to try disabling the other plugins though. We are looking for a conflict and want to see if DynamicFieldsPlugin works on your Trac instance with the other plugins disabled. Conflicts occur regularly with these JavaScript-based plugins.

[torsten.piotraschke@…]

Oh, I'm sorry. I'll give you infos about that tonight (UTC).

[torsten.piotraschke@…]

Alright, I just disabled every plugin, left all modules of the DynamicFieldsPlugin enabled and rebooted. But I still get the spec.rule error. I didn't disable any plugin listed in the "Trac 1.0.4" plugin (i. e. trac.about.*, trac.admin.api.* etc.).

[torsten <torsten.piotraschke@…>]

Forget what I just said. I noticed some inconsistencies in my activations in the components section of my trac.ini. There's no jscript error anymore, but the hide function is still not working.

I'll stay with what I said in comment:7 and will be back tonight.

[Ryan J Ollos]

Replying to torsten <torsten.piotraschke@…>:

There's no jscript error anymore, but the hide function is still not working.

I've noticed that a field is always hidden when hide_always is specified, whether it is true or false. Is that the most recent behavior you were seeing? I'll fix that issue in this ticket.

[torsten.piotraschke@…]

No, unfortunately not. The behaviour I was witnessing was that no command ever worked. When I was specifiying hide_always true, the field was still visible.

[Ryan J Ollos]

Could you try installing again with r14719 of the plugin (dynamicfieldsplugin/trunk​)? It would also be good to confirm that dynfields.js, layout.js and rules.js are added to the page.

[torsten.piotraschke@…]

I installed the current trunk from here. I unzipped it on our trac server, built it by executing python setup.py bdist_egg and copied the egg to the plugin folder.

Using Firefox' inspector, I could see that the files in question spawn [HTTP/1.1 404 Not Found 2ms] errors.

[Ryan J Ollos]

Are you running a web server? You may need to deploy your static assets: ​trac:TracInstall#MappingStaticResources.

[torsten.piotraschke@…]

Yes, I'm running Apache. I'll have a look at the link.

[Ryan J Ollos]

Closing as worksforme, but feel free to reopen if you make more progress on installing the latest version of the plugin and redeploying the static files.
