Prevent img to increase the page width.

Most listbox functionnalities are not supported by web_js_style for now, as no form is used by default

Their contents is already provided by the HTML page template.

Generate a hfeed in the HTML rendering.

we have such error:
....
if context.getValidationState() in ["draft", "deleted", "cancelled", "archived"]:
  Module Products.ERP5Type.Accessor.WorkflowState, line 60, in __call__
    return wf._getWorkflowStateOf(instance, id_only=1)
  Module Products.ERP5Type.Core.Workflow, line 609, in _getWorkflowStateOf
    state_id = 'state_' + status.get(self.getStateVariable(), None)
TypeError: cannot concatenate 'str' and 'NoneType' objects

This stopped working long time ago, probably with slapos commit aa102f28f
(erp5testnode: use newer shellinabox, with a caddy frontend, 2018-09-21)

Web Site/Section were still indexable when rendering in xhtml style.

using parallel list fields cause HTML to be very big and is not good
for usability, because we typically select a lot of values in these fields.

This can sometimes be useful during development

See merge request !1502

ERP5ReportTestCase also import ERP5TypeTestCase, so if we reload it it
patches again getRequest to a function calling itself and causing
RecursionError.

If ignore_layout=1 is present in url query, static web section show the default view so user can modify properties

But for url like
https://erp5/web_site_module/static_web_site/web_page_module/111?ignore_layout:int=1&portal_skin=Slide...
static web section should do redirection instead of showing the default view

It's difficult to distinguish if it should do redirection or show the
default view for all kinds of url

To make it simple, if portal_skin is present in url query, static web
section will do redirection event if ignore_layout is present

Double translation happened when:

- For sql_catalog.isValidColumn(name)
- When search_columns is empty
- When selection_sort_order and sort_columns are empty

So delaying translation on column titles until *_column_list are finalised.

Before this fix, double translation on Sale Order title was happened every time
displaying a Sale Order Line, for example.

Category spreadsheet import did not delete categories if some documents
where related to these categories. While this may make sense when using
this import in site with already some data, in many cases, we want to
be able to delete the categories, so that the result is that the category
tree match the imported spreadsheet.

This extend the dialog to support a new "force delete" mode that delete
categories even if they are use, leaving the documents using categories
with broken relations.

Spotted when comparing this code with ZPublisher.Publish.

Once a response has been written to, the status and headers are supposed
to have been sent over the network. So any future change to them is moot.
Likewise, setBody does nothing: only write can continue appending to the
existing body.
As in the case of WSGI the response does not actually get sent just yet:
- lock the body
- store finalize() result
Also, make the order in which body and stdout are returned consistent with
HTTPResponse: body is returned first (as part of HTTPResponse.write's call
to self.outputBody, which calls self.__str__, which emits body), and then
stdout content.
Also, add support for cases whre the existing body is a file or an
IUnboundStreamIterator.
