Hi,all:
in 2.1.6,Forms add widget state.I have test it yesterday and found some
problems and questions.
Questions:
In V2 flowscript,I can set widget state:
var name=form.lookupWidget("name");
name.state="disabled";
but in V1,I can get but set will produce an error:
var name=form.lookupWidget("name");
print(name.state); //works here
name.state="disabled"; //error here.
The error is like can't convert disabled to Widgetstate ....
How can I change a widget's state in V1?
Suggestions:
I use forms block to develop a real application,some application's
requirements here:
i) Widgets can't be displayed under some conditions
ii) Widgets should be read-only under some conditions
In 2.1.5.1,My solutions are:
To i),Use jxtemplates with <jx:if> to control display the widget or not
To ii),a)Use jxtemplates with <jx:if> to add <fi:styling> disabled to the
widget
b)Use two widget,one is <fd:field> another is <fd:output>,using
<jx:if> to control display one of them.If need to edit ,display the field
widget,if need to display only ,make the field widget hidden and display the
output widget(set its value using flowscript).I can't using <fi:styling
type="output"/> because this will make the field widget's value empty after
save.
I don't like these solutions because they all need coding in jxtemplate,mix
UI and logic.
2.1.6 add widget state,now has 3 state:active,disabled,invisible.It seems
disabled and invisible state can help me to make a better solutions,but here's
the problem:
1.State disabled render a widget with disabled attribute,just like my
solution ii) a),but can't do the same effaces like ii).b).I try to modify
forms-field-styling.xsl,found if only display value,the field widget's value
will be empty after save.
2.State invisible just make a widget can't be used,and I can't use it for
i) because if my style page using the invisible widget will produce exception
like don't have this element ...
My suggestions are:
A)If a widget's state is invisible,let render knows it is invisible,don't
delete the widget.We can make the widget invisible by modify
forms-field-styling.xsl.
B)To state disabled,we can keep current display method using input disabled
attributed,but the widget's value shouldn't get from the request.This allow
user adjust forms-field-styling.xsl to just display text in final page.
C)If B) is not a good suggestion,then make <fi:styling="output"/> just like
<fd:output> to keep it's original value or make it possible to change one
widget's type form field to output.
WDYT?
