Force full or partial update in vpe plugin

[kukeltje]

Some of the elements I have, depend on values of other, not nested or parent elements. If I change one of these elements, I'd like to be able force an update of these dependend elements or a full update (like done bij clicking on the 'circular arrows' in the visual editor)

Are there any pointers on how to achieve this?

For now no direct mechanism force for updating elements, you can manipulate of update element for which template was created by overriding method isRecreateAtAttrChange(..) of VpeAbstractTemplate.
Also you can see VpeVisualDomBuilder class, line 967. Here exists such code
// TODO Ssergey Vasilyev make a common code for figuring out
// if it is need to update parent node or not
private Node getNodeForUpdate(Node sourceNode) {
/* Changing of or tags can affect whole the table */
Node sourceTable = getParentTable(sourceNode, 2);
if (sourceTable != null) {
return sourceTable;
}

/* Changing of an tag can affect the parent select */
Node sourceSelect = getParentSelect(sourceNode);
if (sourceSelect != null) {
return sourceSelect;
}

return sourceNode;
}
but common code, hasn't been created yet.

I akready override that method (returns always true). The getNodeForUpdate is what I was looking for (I think). Will look into that

ok, I've been looking into this... When I select the parent node that needs updating myself and pass that into updateNode like

 Node updateNode = ComponentUtil.getParentElementByName(sourceElement, XForms.TAG_REPEAT);
 pageContext.getVisualBuilder().updateNode(updateNode);

My whole page becomes empty. I do this right before I return from the create method in my template.

Any other suggestions?

uuuhhhhhhhmmmmmmmmm guys, have you seen that the in the VpeAbstractTemplate the method is called getNodeForUptate (with a t instead of a d) that is why I implemented things wrongly I think.

Refactoring would be wise ;-) Now lets check if that does work :-)

hmm - report that in jira so we won't forget - thanks

[kukeltje]

cool... overriding getNodeForUptate works... thanks.....
