Hi Benjamin,
we are using a graphical js-editor based on mxGraph
(http://www.jgraph.com/mxgraph.html) which currently uses a webservice
to perform CRUD operations and runs in an org.eclipse.swt.browser.Browser.
Because a) we experience massive XSS-related issue in our development
environment and b) need to connect to the RAP-Lifecycle chain to receive
events generated by a PhaseListener, we decided to wrap it into a custom
widget.
Since we also want to remove the direct access to the webservice, we
want to proxy all CRUD operations through the RAP application. To
simplify these proxy operations, it would be great to reuse the
BrowserFunction-Infrastructure.
For now, I came up with a Copy&Paste-Solution, which seems to work ok
(widget is a Browser-subclass, the LCA is mainly
org.eclipse.swt.internal.browser.browserkit.BrowserLCA but with some
altered static Strings, the JS-resource is a copied Browser.js with some
modifications.)
Since I don not like such hacks, maybe in the future an infrastructure
may be provided, to simplify use-cases like this. Maybe by Mixins and a
non-final BrowserLCA.
I hope you got my use-case and my approach. Hope there was no one-liner
solution which I didn't see to solve my task ;)
Regards,
Philipp

Hi Philipp,
I think I understood your usecase. But what strikes me: Why do you need
to modify the BrowserWidget? Is it not possible to use the browser
widget as is? I don't really get why you need to touch the BrowserLCA in
this case.
Regards,
Ben

Hi Ben,
since I needed to do some custom stuff on the JS-side, I decided to use
a Copy&Past version of Browser.js, but I changed the class-name.
This change clashed with the QX_TYPE, EXECUTED_FUNCTION_NAME,
EXECUTED_FUNCTION_RESULT and EXECUTED_FUNCTION_ERROR static strings in
the BrowserLCA, so I also needed a copy of it.
I hope, it's clear now. Maybe this is a not so uncommon use-case, so
propably there should be a way to simplify things like this.
Regards,
Philipp
