Hello Everyone, My first post.
I have been studying ofbiz for a month now but I am stuck badly. I
am trying
to calculate the totals of every result returned by find payments
search.
What I am trying to do is somewhat similar to the way that the
Trialbalance
form of the ReportFinancialSummaryForms.xml (the debitTotal and the
creditTotal fields). In the ListPayments form in the
PaymentForms.xml.
I started by placing the following line under the <actions> element
of the
FindPayments screen of the PaymentScreen.xml file.
<set field="parameters.total" value="0" type="BigDecimal"/>
also under the <row-actions> of the ListPayments form in
PaymentForms.xml I
placed the following two lines.
<set field="total" from-field="parameters.total" type="BigDecimal"/>
<set field="total" value="${bsh:total.add(amountToApply)}"
type="BigDecimal"/>
This could be a problem: you are resetting the "total" variable each
time back to the value of "parameters.total".

And Finally because I want to display the result temporarily on a
field, I
placed the following line someone in this ListPayments Form.
<field name="total"><display also-hidden="false"
description="${total}"/></field>
First of all It does not work so I have few question for generous
bros out
there.
Is what I am trying acheivable?
If yes, I know the search result is placed in a list Iterator object
('listIt') returned by the performFind service, is there a way of
iterating
through this list and and get the amount from each record?
and lastly, I have tried few times but never succeeded, is it
possible to
make a form display a field that has not been defined in the entity
that
populates it? sorry if I confuse you with my poor discription of the
last
question.
Thanks alot your help is appreciated.
