Adding Filter Operator

Hello, 
 
I have a filter with "IN" operation. During the execution of report, based on the criteria I want to add dynamically 1 more operator "LIKE". Is it possible to do ? I am using BIRT 2.3.1 
 
When I add the following code in "Before Factory" 
 
if( params["ChoosePrimaryClient"].value[0] == '0') 
{ 
importPackage(Packages.org.eclipse.birt.report.model.api); 
importPackage(Packages.org.eclipse.birt.report.model.api.elements); 
dshandle = reportContext.getReportRunnable().designHandle.getDesignHandle().findDataSet("AchievementTrackingDataSet"); 
filters = dshandle.filtersIterator(); 
while( filters.hasNext() ) 
{ 
filterHandle = filters.next(); 
if( filterHandle.getExpr().indexOf("AGENCY_CLIENT_ID") >= 0 ) 
{ 
dshandle.removeFilter( filterHandle.getStructure() ); 
} 
} 
} 
else if(params["ChooseHouseholdMember"].value[0] == '0') 
{ 
importPackage(Packages.org.eclipse.birt.report.model.api); 
importPackage(Packages.org.eclipse.birt.report.model.api.elements); 
dshandle = reportContext.getReportRunnable().designHandle.getDesignHandle().findDataSet("AchievementTrackingDataSet"); 
filters = dshandle.filtersIterator(); 
while( filters.hasNext() ) 
{ 
filterHandle = filters.next(); 
if( filterHandle.getExpr().indexOf("AGENCY_CLIENT_ID") >= 0 ) 
{ 
origOperator = filterHandle.getOperator(); 
origValue1 = filterHandle.getValue1(); 
fc = StructureFactory.createFilterCond(); 
fc.setExpr("dataSetRow["AGENCY_CLIENT_ID"]"); 
fc.setOperator(origOperator); 
fc.setValue1(origValue1); 
fc.setOperator(DesignChoiceConstants.FILTER_OPERATOR_LIKE); 
value2 = '%'; 
fc.setValue2(value2.toString()); 
dshandle.removeFilter( filterHandle.getStructure() ); 
dshandle.addFilter(fc); 
} 
} 
}
