Re: render nested component

[Qbyte Consulting]

ok ignore that, bumped into some tapestry4 source

would this be the approach?

  JSONObject

spec = new JSONObject
("clientId",
clientId);

171 




172 




e.attribute
("id",
clientId);

173 




174 




spec.put
("leaf",
node.isLeaf 
());

175 




176 




if (hasChildren)

177 




{

178 




Link

expandChildren = resources
.createEventLink
("expandChildren",
node.getId 
());

179 




Link

markExpanded = resources
.createEventLink

Tree uses BaseComponent that doesn't seem to be in tapestry5?

Re: tapestry jquery PageScroll

Thank you for reply.

I was not aware of tests for tapestry5-jquery

I manage to get it working, but now it's trying to fetch data for every
scroll.
Is there a way how to pass restrictions to the jquery script? For example
at the bottom of the page and only for scrolling down.

Re: tapestry jquery PageScroll

[françois facon]

There is some documentation from the author of this component available at
https://tawus.wordpress.com/2012/11/25/scrolling-pages-tapestry5-onscrollbeyond/

if you have a look at the source doc,
https://github.com/got5/tapestry5-jquery/blob/master/src/main/java/org/got5/tapestry5/jquery/components/PageScroll.java
you will find the following code

@Parameter(value = "literal:[]")
private Object[] context;

I guess that you get your code form the sample at
https://github.com/got5/tapestry5-jquery/blob/master/src/test/resources/org/got5/tapestry5/jquery/pages/PageScroll.tml

Your error message

java.lang.RuntimeExceptionCoercion of [] to type java.lang.Integer
(via String --> Long, Long --> Integer) failed: For input string: "[]"
java.lang.NumberFormatExceptionFor input string: "[]"

come from the default value of the parameter context you have removed from
the template.

see also https://tapestry.apache.org/component-parameters.html for more
details about parameter binding.

for questions related to tapestry5 jquery component, I suggest you to open
an issue at https://github.com/got5/tapestry5-jquery/issues.

Re: exception during bind

[Kalle Korhonen]

You have the wrong version of plastic and/or JRE. (And for the love of god,
please learn to post a proper question and include at least some context,
like versions of libraries you are using.)
