Multiple Select in Maximo

Requirement

Implementation

1. Add values in Libraries For our this custom multi select menu we need to add some code in Library and Lookup. Go to Application designer click on Select Action drop down. There select export System XML. This will open the following dialog. In the dialog click the arrow against lookups and library. This will download lookups.xml and library.xml





a. Lookup.xml You can use any lookup any lookup but it should have selectmode="multiple". I created a new lookup. For this open lookups.xml insert in the bottom of the file the following lines

<table id="multicustomlookup" inputmode="readonly" 

 
b. Library.xml Open the downloaded library.xml
In this file search for this code snippet

 <dialog beanclass="psdi.webclient.system.beans.LookupBean" icon="img_lookup.gif" id="query_lookup" label="Select Value"> 
	<lookup id="querylookupcontrol"/> 
	<buttongroup id="querylookup_3"> 
		<pushbutton default="true" id="querylookup_3_1" label="OK" mxevent="dialogok"/> 
		<pushbutton id="querylookup_3_2" label="Cancel" mxevent="dialogcancel"/> 
	</buttongroup>
</dialog>

Replace it with the following code. The only change is that change it with your custom bean class which we will write in next section beanclass="yourpackage.MLMultiSelect"

<dialog 

Save the file and import both files (lookups.xml and library.xml) back in to Maximo by using the import application definition in Maximo.

2. Application Designer In application designer open the application you need to add multi select lookup into. Select the attribute you want to edit. Right click – Properties. In the lookup field insert multicustomlookup . Save the application.

3. Java Code Create a new class file. Past the the following code in it.

        //In my requirement if the user selects "Not Applicable" then he should not select any other value with it.
        if (fieldToSet.equalsIgnoreCase("MYCUSTOMFIELD") && commaString.contains("Not Applicable")) {

        //End Custom Specific Rules
