Fix block cache

[Pierre Buyle]

By default, block content is cached per role (see http://api.drupal.org/hook_block).

When the UD Header block is retrieved from cache, the udheader_build_block function is not invokated and the udheader-style.css file is not added to the CSS. See http://drupal.org/node/214856

Also, when using t() to translate header text (as suggested in bug #443439), the translated content is cached for all languages.

Adding $block[0]['cache']=BLOCK_NO_CACHE in udheader_block() should disable cache for the UD Header and solve these issues.

This is fixed in r21.

Instead of disabling the cache function, I added hook_init so the css will always be rendered with the block instead of after. This will ensure the cached version has the CSS as well.

Blocks are not cached per page. If the UD Header block is cached for a node page with a type-specific header, next pages will use that specific header and not the default one.

Thanks for letting me know. I used the exact line you gave me and tossed it out as r23.
