Re: comparing two dates using use-when

Hi All
Please all I need help on using the use-when attribute
I've made a product status field in the form and I want to check for that
field this field s string and I can't use use- when with strings
what I have done is this:
        <actions>
        <set field="productStatus" value="product.ProductStatusId"/>
        </actions>
This was to store the status of the product

this is to change target when the status equals "Periodic Mass Load"
        <alt-target use-when="${productStatus.equals('Periodic Mass Load')}"
target="updateProductChangeStatusPeriodicMassReady"/>

this is a submit button I want to use also if the status matches this value
"Periodic Mass Load"

	    <field name="submitButton" title="Periodic Mass Ready"
use-when="${productStatus.equals('Periodic Mass Load')}"
widget-style="smallSubmit"><submit button-type="button"/></field>

anyone can help or give me a link to read?
I duno how to check strings. I tried to remove spaces but the problem
remains te same.
Instead of single quotes I put double quote and the same problem remains

here's the exception

Re: comparing two dates using use-when

Posted by Jacques Le Roux <ja...@les7arts.com>.
You must put actions before al-target (if you use an XML content aware editor you should see that). You can use use-when in an 
alt-target.

Unfortunatley due to some inconsistence still in OFBiz, when you use use-when you actually use underneath a BSH syntax and not a 
Groovy syntax. So inside the use-when expression you need to use &amp; &apos; &gt; &lt; &quot; instead of & " > < '.
You should find enough examples OOTB. 

Adrian suggested to use an UEL functions, I never tried that

Re: comparing two dates using use-when

It seem I don't have enough infoirmation about use-when attribute. does
anyone have?
everything goes right when I use it to check if something is null or not but
when I do further checking it deosn't go right
the use-when is widely used in ofbiz to check if something is null or not or
the map in the conext is null or not
but what I want to do now is to check if the productStatus equals certain
value or not and the checking always gives me negative answer
something strange happens as well
<form name="EditProduct" type="single" target="updateProduct" title=""
default-map-name="product"
        header-row-style="header-row" default-table-style="basic-table">
        <actions>
       <set field="productStatus"
from-field="product.productStatusId"></set>
        </actions>
when I go to print the productStatus it doesn't print the status it's not
null but prints nothing on the screen I put the actions before alt-target
because I'll need it to decide which target shall i go to.
Am I putting the actions in a wrong place?
does anyone have any suggestion to use different submit buttons and
different targets based on product status?

you may also try following if your problem did solved.

&quot;Periodic Mass Load&quot;.equals(productStatus)
