Hello,
I need to insert a new sub-component into a page during the request-
response cycle (probably within appendToResponse() )
I thought I had achieved this, but all the links on the page are now
broken (and other general weirdness unfolds)
This is the essence what I need to achieve (I removed all the
specific crud that you don't need)
This breaks:
public void appendToResponse(WOResponse a_rsp, WOContext a_ctx) {
super.appendToResponse(a_rsp, a_ctx);
// Prepare a sub-component (then pass it bindings, etc..)
// DisplayArticle generatedContent = ((ERXApplication)
ERXApplication.application()).pageWithName(DisplayArticle.class,
a_ctx); // the other way
DisplayArticle newComponent = (DisplayArticle)pageWithName
("DisplayArticle");
String generatedContentForCMSTag = newComponent.generateResponse
().contentString();
// Do stuff
// Update a_rsp.setContent(adjustedContent);
}
I need this to not break.
I suspect that this is messing up the object graph that it uses when
invokeAction and takeValuesFromRequest is called.
Do I need to register (or unregister) these components somehow after
they are created.
The DisplayArticle component ONLY ever use direct actions, so I will
not be using normal actions within these.
They do however need to retain their session info.

This might look a little bit mad (when out of context), so if you are
interested, this is why I want to do it:
I am parsing 'a_rsp.contentString();' using a regex so that I can
locate tags that may appear (these tags may have come from a string
(from a content managed article in the database)
These are in the form:
<cms:DisplayTitle displayTitle = "About Us" linkToArticle = "Y"
artTitle = "About Us" />
The plan is to find these, and replace them with a generated
component (into which I pass those bindings)
The cool thing is, that the inserted article can also contain one of
these tags, hence we have a simple content management structure.
If there is a better way to do this, feel free to enlighten me.
Thanks in advance,
Mark
