Understanding LCA readData method [message #76527]

I have a question regarding readData method in the LCA class.

My widget extends "qx.ui.basic.Label" so I belive it should inherit all
properties from Label. Thing is that when I do:

String text = WidgetLCAUtil.readPropertyValue(widget, "text");

The text variable is always null. Am I doing something wrong here? How can I
get in Java the JS text property on-demand (like when doing a getText())?

Thanks

Tiago

Hi Tiago,

readPropertyValue reads the value of an given attribute from the request
sent by the client. If there is no value for the given attribute it
returns null. As the label is from the perspective of the client is a
read-only widget, it doesn't sent any values back to the server - this
explains why you always get null.

Ciao
Frank
