Hi Jesse,
I guess the far most easiest way to achieve this, is to change your
local gridtext-component (in "lps/components/lz/gridtext.lzx").
You only need to override the "updateData()"-method in the gridtext's
editbox and handle in that place your node-creation code.
For instance like that:
@@ -106,6 +106,15 @@
this.globalMouseDel = new LzDelegate( this,
"checkMouse" );
super.init();
+ </method>
+ <method name="updateData" >
+ var ret = super.updateData();
+
+ if (this.datapath.p == null) {
+
this.datapath.context.addNode("description", ret);//for a
"description/text()" datapath
+ }
+
+ return ret;
</method>
<method name="applyData" args="d">
//because of the monkeying with init that this
Hello,
In a databound grid, I want to use a <gridtext> for an "optional" node
in the dataset; ie. the gridtext datapath ("Description/text()") may not
match anything, and that's ok. It works fine if there is a match, but
if there isn't for that row, I'd like to be able to create a node (the
Description) when text is entered. Any clues how that can be done?
Further info: in that case, when there's no matching node, trying to
enter text prints the error "setNodeText: p is null in Datapath ...".
I've tried doEnterDown() and various events to try to catch that and
create a node, but they don't "fire," I think due to that error. I'm
using 4.0.11.
