Is there a stack trace? It would be useful to know which object it was looking up “value” on.

It is on the component that holds the commented WOString. So, in the case of ERQMAjaxUpdateContainer:

<com.webobjects.foundation.NSKeyValueCoding$UnknownKeyException message '[<er.jqm.components.core.ERQMAjaxUpdateContainer name: er.jqm.components.core.ERQMAjaxUpdateContainer subcomponents: null > valueForKey()]: lookup of unknown key: 'value'. The WOComponent er.jqm.components.core.ERQMAjaxUpdateContainer does not have an instance variable of the name value or _value, nor a method of the name value, _value, getValue, or _getValue' object '<er.jqm.components.core.ERQMAjaxUpdateContainer name: er.jqm.components.core.ERQMAjaxUpdateContainer subcomponents: null >' key 'value’>

When I put this into Main.html

<!-- <wo:WOString value="$now" /> —>

Is says:

<com.webobjects.foundation.NSKeyValueCoding$UnknownKeyException message '[<com.msp.components.Main name: com.msp.components.Main subcomponents: {0 = <com.msp.components.WrapperA name: com.msp.components.WrapperA subcomponents: null >; } > valueForKey()]: lookup of unknown key: 'value'. The WOComponent com.msp.components.Main does not have an instance variable of the name value or _value, nor a method of the name value, _value, getValue, or _getValue' object '<com.msp.components.Main name: com.msp.components.Main subcomponents: {0 = <com.msp.components.WrapperA name: com.msp.components.WrapperA subcomponents: null >; } >' key 'value'>

Also worth mentioning, that I tweaked ERQMAjaxUpdateContainer.html to use the WOD type binding instead, and that works fine.

<wo:genericContainerelementName="$elementName"otherTagString="$otherTagString">

  <!-- _ju:<webobject name = "elementID"/> -->

  <wo:content/>

  <!-- _ju:<webobject name = "elementID"/> -->

</wo:genericContainer>

——

elementID :
WOString {
 
value =
_javascript_ElementID;
}

Very odd indeed.

Subject: ERQMAjaxUpdateContainer : lookup of unknown key: 'value'

Hi,

Short Story:

The problem (in my app) appears to be that put a WOstring in an html comment (with an WOGNL $ binding), it throws [ lookup of unknown key: ‘value’. ] e.g.



<wo:content/>



</wo:genericContainer>

-------

In the example (jQueryMobileExample), it works great and

<wo:ERQMAjaxUpdateContainerid="AUCShowValues">

renders as:
<div id="AUCShowValues">
<!-- _ju:AUCShowValues —>

..

.. etc

In my app it throw [ lookup of unknown key: ‘value’ ]

The problem (in my app) appears to be that put a WOstring in a comment (with an WOGNL $ binding), it fails to work.

I demonstrated this by trying:

<!-- <wo:WOString value="$now" /> —>

and the same issue occurs (lookup of unknown key: ‘value')

Notes that the following do work as expected:

<wo:WOString value="$now" />

<!-- <wo:WOString value="hello" /> —>

There must be some setting I have missed, but I cannot see any obvious differences between the ‘example’ and my code.

I have tried changing -WOIncludeCommentsInResponse, but that didn’t make any difference.

Any ideas?

Thanks,

Mark Gowdy
